D-Sub9 Socket to Terminal Block with Push Button DeLOCK 66557

The DeLOCK D-Sub9 female to Terminal Block with Push Button (MPN: 66557, EAN: 4043619665570) is an adapter that converts a D-Sub9 female interface to a pluggable terminal block for direct connection of bare wires. With compact dimensions (32 mm width, 30 mm depth, 20 mm height) and an operating temperature range from -10 °C to 70 °C, it is suitable for small installations where a reliable, removable wire connection is required. The unit is finished in green and includes a push-button mechanism to release the terminal block quickly.

Advantages

The adapter allows secure and tool-free removal of connected wires via its push-button release. Its compact form factor saves space in confined setups while maintaining compatibility with standard D-Sub9 female ports. The specified operating temperature range supports use in typical indoor and light-industrial environments. The terminal block design enables direct connection of bare conductors without the need for soldering or crimped connectors.

Suitable for

• Connecting bare wires to devices with a D-Sub9 female interface
• Small industrial control panels and instrumentation
• Hobby projects such as model railway wiring
• Prototyping and temporary test setups

How to use

Insert the adapter into the corresponding D-Sub9 male connector on your device. Strip the insulation from the wire ends according to wire size recommendations, insert the bare conductors into the terminal block ports, and secure them using the push-button release mechanism as described by the connector alignment. To remove wires, press the push button to release the clamping mechanism and withdraw the conductors. Ensure the device is powered off before connecting or disconnecting wires.

Recommendations

Use the adapter for low-voltage signal and control lines only; confirm conductor cross-section compatibility with the terminal block before installation and avoid exposure to conditions outside the stated temperature range.
