DELOCK D-Sub 25 pin male to RJ12 female assembly kit, blue

Assembly kit by DELOCK for creating a cable with a D-Sub 25 pin male connector on one end and an RJ12 female connector on the other. This kit enables conversion of a D-Sub 25 serial interface to an RJ12 connection, allowing extension of serial or peripheral connections over telephone/ISDN or RJ12 cable. The blue housing contains interchangeable contact positions so the D-Sub 25 wiring can be assigned individually to match the required pinout. Contacts snap into the D-Sub housing with a slight click to ensure secure and reliable contact during use.

Advantages

The DELOCK D-Sub 25 male to RJ12 female assembly kit provides flexibility for custom cabling and repair tasks. Individual assignment of D-Sub contacts lets you adapt the wiring to different serial or peripheral protocols without needing a permanently wired adapter. The snap-in contact design simplifies assembly and reduces the risk of loose connections, while the compact blue housing is suited for confined installation spaces. The kit approach allows on-site termination and fast replacement of damaged connectors.

Suitable for

• Custom serial cable assemblies where a D-Sub 25 must be converted to RJ12
• Repair and field service for equipment using D-Sub 25 to RJ12 interfaces
• Extending serial or peripheral connections over telephone/ISDN or RJ12 cabling
• Prototyping and testing different pinouts for legacy equipment

Key specifications

• Connector 1: D-Sub 25 pin, male, configurable contact positions
• Connector 2: RJ12, female
• Housing colour: blue
• Includes components for one assembled cable end
• Suitable for telephone/ISDN/RJ12 cable use and serial/peripheral signal routing

How to use

Prepare the cable by stripping and arranging the wires according to the desired pinout. Insert individual contacts into the D-Sub 25 housing at the required positions until they click into place. Terminate the other end to the RJ12 female module following the RJ12 contact order. Verify continuity and correct wiring with a multimeter or cable tester before connecting to equipment. Ensure the assembled connectors are seated and secured to avoid strain on the contacts.

Recommendations

Before final installation, confirm the target device pinout and signal assignments to prevent mismatches. Use appropriate cable types for the application and avoid excessive bending near the connector. Test the assembled connection for continuity and correct signal routing prior to live operation.
