Say goodbye to the interruptions of accidental disconnections, knowing your equipment will receive steady power.
Multi-Use Power Solution for Professional Use
For integrators managing a wide variety of projects, versatility and reliability are large selling points in the design-build world. The Locking DC Power Cable series is designed for broad use across professional and industrial applications. Core models, such as the Locking DC Extension Power Cable and Right-Angle Locking DC Male Pigtail, are compatible with a wide range of 12V/24V devices. A single, high-reliability product line serves as an all-in-one standard for security installations, commercial displays, kiosks, broadcast equipment, and factory automation. The versatile form factor simplifies your supply chain, enabling you to quickly procure a reliable power solution for nearly any device with a 5.5mm DC jack.
Built for Reliability with Top-Grade Internal Components
Although the locking connector protects against external interference, the internal build of a cable determines its long-term performance. We use UL2464 2-core 18 AWG wire to ensure durability in the core. This standard means the cable has excellent crack and wear resistance, good flexibility, and retains its shape throughout its lifespan. The 18AWG pure copper conductors support efficient power delivery with minimal voltage drop. This dedication to high-quality materials is what makes our Locking DC Cable both a safe and reliable option, preserving your equipment investments while accomplishing the twin task of minimizing field failures and maintenance callbacks.
Create A Solid Base For Safe, Long-Lasting Installations
End-users hope the equipment will work without issues, and a poor power connection is a primary failure mode. This specific problem is what our Locking DC Power Cable is designed to tackle through a combination of features. The nut-Lock secures it mechanically, the UL2464 2-core 18AWG wire maintains electrical integrity, and the industrial build guarantees physical longevity. In combination, they create a stable and robust power connection. This factor is crucial in certain applications, such as industrial control panels, medical carts, and public information displays, where safety and uptime are not negotiable. Opting for our locking cables means you are choosing peace of mind for your projects.
The biggest advantage is security. The threaded locking mechanism is important because it keeps the connector firmly in place and doesn’t allow vibrations to loosen it or even accidentally pull out during operation, which in less secure connectors is so likely to happen with industrial equipment more exposed, on military vehicles set to harsh conditions or even public installations like digital signage and video surveillance cameras, for example, that need a permanent power supply.
The numbers are the outer barrel diameter (5.5mm) and the inner pin diameter (2.1mm or 2.5mm). They are not interchangeable. You will need to ensure the connectors on both ends are exact and match the size and shape of your device’s DC jack. If you insert the wrong size, it could damage the port or cause a poor connection.
Right-angle connectors are ideal for installation in confined spaces, where a straight plug will be too long or place excessive strain on the cable behind wall-mounted monitors, inside tight equipment cases, and on densely-packed video walls.
Have Locking DC Male Pigtail or Female Pigtail wire for permanent wiring. The pigtail end (stripped/tinned wires) is hardwired into a power source in an enclosure, but the locking connector provides a secure detachable point for the actual end device. That makes it perfect for custom panels and machine rooms with centralized power distribution.
Push-pull locking rather than a thread. All you have to do is shove the connector in to secure it, and pull it out to unlock it.
This cable provides a way to run/charge devices with a common DC jack (e.g., mini-PCs, routers, etc., monitors) from a modern USB-C Power Delivery (PD)-capable power source (like a laptop charger or PD power bank), using the new USB-C connection while still providing stability by locking securely in place.
This cable is key to the film, photography, and broadcast industries. It draws power directly from the D-Tap (also known as P-Tap, Power Tap) output port of a professional camera or light and provides it via a secure, reliable built-in DC Locking Power Cable to accessories such as monitors, recorders, or field transmitters.
All our DC cables are made with 18AWG pure copper conductors in these cables, up to a maximum of 5A current rating, together supporting most of the 12V/24V DC useful devices, including powerful LED panels and motorized security cameras.

More About Locking DC Power Cable of Bespokecable
Quality & Testing
All locking DC Power Cords are subject to strict quality protocol. As a professional manufacturer, Bespokecable follows the adage of “Failure is not an option”. Using UL 2464-compliant 18 AWG cables and precision-machined brass locking connectors as your starting point. The most important test is on the lock cylinder itself. A torque and pull-force test is performed on each connector to confirm that the threaded collar or push-pull latch holds the connection after meters of interaction and under mechanical stress. It also means the Locking DC Plug Cable provides resistance to vibration and accidental disconnection. Each cable also undergoes a rigorous electrical test to verify continuity, correct polarity, and adequate insulation resistance to prevent short circuits. With the available 2.5mm Locking DC Power Cable and the 5.5×2.1mm versions to verify proper fit & electrical contact between the inner pin. This multi-point validation ensures that every shipped Lock Type DC Power Cable meets the reliability level required for industrial, security, and commercial applications.

Using a Locking DC Plug Cable is critical for long life and reliable operation, proper installation. Refer to this step-wise guide for connecting securely:
- Preparation: Determine the correct-size connector for your device’s DC jack (5.5×2.1 mm or 5.5×2.5 mm). Consult the polarity identifications on both ends of the cable, which, in general, are (+) positive on the inner pin and (-) negative on the outer sleeve, and your gear.
- Steps to use: Making the connection – Match the plug to the DC port of your device. For a threaded-locking type, insert the plug with light pressure, then rotate the outer collar clockwise to clamp tightly. Hand tightens until firm; don’t over-torque with a socket. If it is a push-pull Lock Type DC Power Cable, we need to align it and push it down hard until you hear or feel a clicking sound.
- Routing and Strain Relief: Route the cable to prevent sharp bends, kinks, or pinch points. Use clips or ties, if appropriate, to provide strain relief adjacent to the interface and avoid direct tension on the connector.
- Test: Turn on the device to make sure it works, then seal it up. When connected well, a Locking DC Power Cord with 2.1mm or 2.5mm will deliver an unshakeable connection that keeps your equipment powered reliably.
Locking DC Power Cable is not just a wire; it is an essential part that system integrators, broadcast engineers, and industrial OEMs have relied on to keep operations up and running. A locking DC cable ensures a firm, vibration- and movement-resistant connection, unlike conventional barrel plugs. But choosing the right one is not as easy as it may seem, on connector size, locking mechanism, and, more importantly, the application environment. As a professional factory and manufacturer of power cords, we have prepared this guide to help you make an informed purchase decision.
1. Check the Connector Size – 2.1mm v/s 2.5mm
The biggest error that you make is thinking all 5.5mm outer barrel connectors are identical. The inner pin diameter is the key dimension and is 2.1mm or 25mm.
- Lock DC Power Cable 2.1mm: This is the more commonly used version. This is generally utilized in customer electronic devices, system hardware, and numerous CCTV Cameras. If you are replacing a generic power cord, it is probably 2.1mm.
- 2.5mm Locking DC Power Cable: Tends to l be used by higher-current devices, professional audio/video built-in devices, and a few medical equipment. It makes its contact surface infinite to improve current flow.
Pro Tip: A 2.5mm plug into a 2.1mm jack-sized hole will not fit. If you insert a 2.1mm plug into a 2.5mm jack, it will be loose and power on/off intermittently. Before you buy, always check your device’s spec sheet and measure the inner pin hole.
2. Use the Right Locking System
Important to note that not all locks are created equal. The option you select depends on whether a fast release or maximum security is required.
- Threaded Nut-Lock (Barrel Jack Style): The original and most secure option. The connector is inserted, and then the collar is threaded to the Device panel thread. This makes it perfect for constant installations such as digital signs, safety uses, and industrial control panels, where vibration is always a worry. It is the most common standard for all locking DC Barrel Jack cables.
- Push-Pull Lock DC Cable: A spring-loaded sleeve mechanism locks this type of cable. You insert it to lock, and pull the sleeve back to unlock. Faster clean release than a threaded nut, ideal for quicker connect/disconnect with broadcast carts, medical carts, and field equipment needing fast setup/strike. As it is reliable for sterilization, it meets the requirements for a Medical Grade Locking DC Cable in many instances.
3. Is The Cable Matched to Your Application
The cable must be appropriate for the environment it will be used in, in terms of construction and features.
- Broadcast & Photography: Locking DC Power Cable for Sony Camera or any other pro camera (D-Tap plug connected to a D-Tap adapter plugged into the monitor/transmitter/camera). In these cases, a Right-Angle Locking DC Extension Power Cable is often used to prevent cables from dangling from the sides, which can be snagged on other objects. A coiled (retractable) cable is a great help with mobile rigs and for managing your cables.
- Medical & Sensitive Environments: In hospitals or labs, equipment reliability is crucial. Check medical-grade materials (usually white PVC), flexible jackets, and a deadlock that prevents the cable from being disconnected during patient transport or procedures.
- Industrial & Outdoor applications: In extreme conditions, use a thick jacket of PVC or PUR, which offers better oil and chemical resistance and greater abrasion resistance. The Locking DC Plug Cable has a metal housing instead of plastic to withstand mechanical stress.
4. We are a direct wholesale manufacturer and recommend focusing on electrical specs and customization.
- Conductor Gauge (AWG): Prevent voltage drop for longer runs by using a thicker wire (lower AWG number). Most of our standard Locking DC Power Cords feature 18 AWG pure-copper conductors, suitable for most applications up to about 5A. If you need to power high-current devices over a long distance (as is common with an SAE Extension Cable), you may want us to build your replacement cables to 16 AWG or even 14 AWG.
- Customization (OEM/ODM): When sourcing in bulk, if it is not a good fit with an off-the-shelf solution. We encourage complete customization of our DC Power Cords, including length, connector gender (male/female), jacket color (black, white, or any custom color), and the addition of ferrite beads for EMI suppression. That’s particularly useful when cable is being worked into an OEM’s own products.
