Gender changer adapter DELOCK 67094 — D-Sub 25 (female/male) to RJ12, red

DELOCK 67094 gender changer adapter converts a 25-pin D-Sub (DB25) connector to an RJ12 interface in a compact, easy-to-identify red housing. The adapter provides a physical conversion between devices or cables that use a D-Sub 25 connection and wiring terminated in a 6-position RJ12 plug, allowing the expansion of serial or communication interfaces via telephone, ISDN or RJ12 cables. Contacts are inserted into the D-Sub 25 housing according to the required assignment and lock into place with a slight click to secure reliable contact.

Advantages

The adapter supports flexible assignment of the D-Sub 25 contacts, enabling custom pin mappings for specific equipment or cable harnesses. Its compact form factor and red colour make it convenient for installations where space is limited and visual identification is beneficial. The snap-in contact design ensures stable electrical connection without soldering or additional tools, simplifying temporary or permanent conversions between DB25 and RJ12 interfaces.

Suitable for

• Connecting serial D-Sub 25 ports to devices using RJ12 (telephone/ISDN) cabling
• Field wiring and quick interface conversions in communication racks
• Lab and test setups where custom DB25-to-RJ12 pinouts are required
• Temporary or portable equipment connections that need easy visual identification

Key specifications

• Connector A: D-Sub 25 (female/male configurable within housing)
• Connector B: RJ12 (6-position modular interface)
• Colour: Red for visual identification
• Number of pieces: 1
• Contact insertion: snap-in contacts for configurable pin assignment

How to use

Insert the RJ12 cable plug into the RJ12 socket of the adapter until it latches. Place the D-Sub 25 contacts into the adapter housing according to the required pin assignment and press until the contacts click into place. Connect the D-Sub 25 side to the corresponding DB25 port on your device or cable assembly. Verify correct pin mapping and signal continuity before applying power or using the connected equipment.

Recommendations

Ensure that the pin assignment between the D-Sub 25 side and the RJ12 wiring matches the requirements of your devices; incorrect mapping can cause communication failures. Use the adapter in dry, dust-free environments and avoid excessive mechanical stress on the connectors. For permanent installations, check contact reliability periodically and secure connected cables to prevent accidental disconnection.
