## Summary description

It comes in black and green colors, providing a reliable solution for connecting devices with different connector types. This product is designed for easy installation and versatility in various applications.

## Long description

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

 Product colour: Green, Black
 Brand: DELOCK
 MPN: 66603
 EAN: 4043619666034
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.
Usage 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.
