DeLOCK 90655 wire connector D-Sub 9 3 pin terminal block Black Grey

The DeLOCK 90655 is a compact D-Sub 9 wire connector with a 3-pin terminal block designed to connect bare wires for serial data communication. The female connector houses the terminal block on a small PCB and is available in black and grey. It is suitable for connecting devices with compatible interfaces such as computers, microcontrollers or industrial controllers. The enclosure protects the terminal block PCB from dirt and mechanical damage while an integrated strain relief secures the cable to the housing.

Advantages

The enclosed D-Sub housing shields the terminal block PCB and exposed contacts, reducing the risk of contamination or accidental damage. The integrated strain relief holds the cable firmly in place to prevent stress on the wire connections. Its compact dimensions (20 mm width, 48 mm depth, 34 mm height) make the connector easy to integrate into tight installations. The product is a female D-Sub 9 connector and complies with CE standards.

Suitable for

• Serial data connections between computers and peripherals
• Connecting microcontrollers and development boards
• Wiring of industrial controllers and automation equipment
• Prototyping and test setups that require bare-wire terminations

How to use

Prepare the bare wires by stripping an appropriate length of insulation for the terminal block. Insert each wire into the corresponding terminal and tighten the terminal screws to secure the conductors. Mount the terminal block inside the D-Sub housing if not preassembled, then close the enclosure to protect the PCB and contacts. Route the cable through the housing and ensure the integrated strain relief is positioned to clamp the cable, preventing movement and reducing mechanical stress on the wire terminations.

Recommendations

Ensure wires are stripped to the correct length and terminal screws are tightened to the manufacturer’s recommended torque. Avoid exposing the connector to excessive moisture or corrosive environments. Use the strain relief to prevent cable pull from transmitting force to the solder joints or terminals.
