DELOCK assembly kit: D-Sub 25 pin female to RJ12 female connector, black

Assembly kit to convert a D-Sub 25 pin female (DB-25) interface to an RJ12 female connection. The kit contains black housings and parts to build a cable or panel adapter that links a 25‑pin D‑Sub socket to a 6‑position RJ12 socket. It is intended for custom cable assemblies and telecommunication or serial/modem wiring where DB‑25 to RJ12 termination is required. Contacts can be placed individually in the D‑Sub housing to match the required pinout, and the sockets snap into place with a slight click to ensure reliable contact.

Advantages

The Delock assembly kit provides flexibility to assign and customise the D‑Sub 25 pin connections according to the specific wiring scheme. Supplied parts are finished in black for a neutral, professional appearance and allow fabrication of either cable-mounted or panel-mounted adapters. The snap-in contact design ensures simple assembly without specialised tooling and delivers stable electrical contact once installed.

Suitable for

• Creating custom DB‑25 to RJ12 cable assemblies
• Panel adapters linking serial or modem equipment to telephone/ISDN lines
• Telecommunication wiring and small-scale proms/repairs
• Prototyping and lab environments requiring configurable pinouts

Key specifications

• Connector types: D‑Sub 25 pin female to RJ12 female
• RJ12: 6 positions (6P)
• Housing colour: black
• Package contents: kit components for one adapter (housing and contact parts)
• Assembly type: user-configurable, snap-in contacts

How to use

Select the required pinout for your application and insert the individual contacts into the D‑Sub 25 housing according to that wiring scheme. Place the RJ12 female socket into its matching housing opening and secure the parts until they click into place. Verify contact seating visually and by gentle pull to confirm the snap-in retention. Terminate the cabling to the contacts following standard wiring practices for serial, modem or telephone lines and perform continuity checks before final installation.

Usage recommendations

For reliable performance, use appropriate wire gauges and insulating sleeves where required, avoid excessive bending near the termination points, and verify pin assignment against device documentation before powering connected equipment. If repeated insertions or harsh environments are expected, perform routine inspections of contact seating and retention.
