DeLOCK 66603 cable gender changer RJ45 4 pin terminal block Black Green

The DeLOCK 66603 cable gender changer provides a compact interface between an RJ45 connector and a 4‑pin terminal block. It is designed to allow bare wires to be connected to equipment with an RJ45 jack, offering a simple solution for adapting signals or power in installations where a soldered or crimped RJ45 cable is not available. The adapter is supplied in black and green and is intended for both industrial and hobby use.

Advantages

The adapter converts an RJ45 plug to a 4‑pin terminal block, enabling direct connection of bare wires without additional tools. Its compact form factor simplifies retrofit and prototyping tasks and reduces the need to modify existing cabling. The device supports quick connection changes and is compatible with standard RJ45 sockets.

Suitable for

• Connecting sensors or low‑voltage devices to systems with RJ45 ports
• Prototyping and development work in workshops or labs
• Industrial installations where field wiring must be connected to RJ45 interfaces

Key specifications

• Connector 1: RJ45
• Connector 2: 4‑pin terminal block

How to use

Insert the RJ45 end into the corresponding RJ45 jack. Strip the insulation from the wires to expose the conductor ends, then insert each bare wire into the appropriate terminal on the 4‑pin block and secure it according to the terminal block mechanism (screw or clamp). Verify connections are secure and, if required, test continuity and polarity before powering the system.

Recommendations

Use this adapter only for low‑voltage signals or power within the connector and wiring specifications. Ensure correct wire assignment to the 4 pins to prevent damage to connected equipment. For permanent installations, consider using strain relief or additional fastening to prevent mechanical stress on the connectors.
