ACT Mountable High-Performance Adapter RJ-45 Socket to 9-Pin D-Sub Plug

The ACT TD09M8 adapter combines a 9-pin D-sub male connector with an RJ-45/RJ-12 female modular connector in a single, mountable housing. The adapter features fixed wiring on the RJ-45/RJ-12 side with crimp contacts at the cable ends that can be placed into the desired positions on the D-sub connector without tools. The housing includes locking screws to secure the D-sub end for a stable connection. The product is grey and intended for use where a reliable interface between D-sub and modular network/telephone cabling is required.

Advantages

The adapter provides a compact, heavy-duty connection solution that simplifies mating between a 9-pin D-sub interface and modular RJ-45/RJ-12 cabling. Fixed modular wiring with crimp contacts allows tool-free placement of conductors into the D-sub shell, and the housing locking screws ensure a firm mechanical attachment. Its mountable design and robust construction make it suitable for installation in rack or panel applications where space and reliability are important.

Suitable for

• Converting a 9-pin D-sub port to a modular RJ-45 or RJ-12 connection
• Industrial and commercial equipment interconnects
• Panel- or rack-mounted cabling where a secure D-sub attachment is required
• Telephone or network modules using RJ-12 or RJ-45 modular plugs

• Connector 1: 09‑pole D‑Sub (male)
• Connector 2: RJ‑45 / RJ‑12 (female, fixed wiring)
• Product colour: Grey
• Mountable housing with locking screws
• Crimp contacts at cable ends for tool-free placement into D‑sub positions

How to use

Terminate the cable to the modular RJ-45 or RJ-12 female connector using crimp contacts according to the required pinout. Insert the crimped conductors into the fixed positions of the modular side; the contacts are designed to be placed without special tools. Align the 9-pin D-sub male connector with the mating D-sub female port and secure the housing using the built-in locking screws to prevent accidental disconnection. Verify continuity and correct pin mapping before commissioning.

Recommendations

Use the adapter in environments where a mechanically secure D-sub connection is needed. Confirm the pinout mapping between the D-sub and the modular connector (RJ-45 vs RJ-12) before installation to avoid signal mismatch. Avoid exposing the adapter to prolonged moisture or corrosive conditions to maintain contact reliability.
