Wire connector Dsub 25-pin EFB Elektronik 29012.1

The EFB Elektronik 29012.1 is a 25-pin D-sub wire connector in black, configured for female connections. With compact outer dimensions of 53.1 mm width, 12.6 mm depth and 20.6 mm height, this connector is designed for panel or cable-mounted electronic applications where space efficiency and standard D-sub interface compatibility are required. Supplied as a single piece per pack, the connector offers a straightforward interface for terminating or extending 25-conductor signal lines.

Advantages

This D-sub 25-pin female connector provides a standardized electrical interface for multi-conductor signal connections, supporting reliable mating with matching male D-sub plugs. The compact housing and black finish minimize visual impact in assemblies while helping to protect contacts. Its dimensions make it suitable for installations with limited clearance, and the single-piece packaging simplifies procurement for small projects or repairs.

Suitable for

• Connecting 25-conductor signal cables for data and control applications
• Panel or enclosure mounting where a female D-sub interface is required
• Repair and replacement of existing D-sub25 female interfaces on equipment
• Prototyping and small-scale electronic assemblies

Key specifications

• Connector type: D-sub, female, 25 contacts
• Colour: black
• External dimensions: 53.1 mm (width) × 12.6 mm (depth) × 20.6 mm (height)
• Mounting style: wire/cable termination (single-piece packaging)
• Quantity: 1 piece per pack

How to use

Prepare the cable by stripping and arranging the 25 conductors according to the required pinout. Insert conductors into the connector's female contacts following the wiring schematic for your device, ensuring secure electrical contact and correct polarity for each signal. After assembly, verify the mechanical retention and if applicable fasten the connector to the panel or cable clamp. Perform continuity checks and, if needed, insulation tests before placing the system into operation.

Recommendations

Use appropriate crimping or soldering methods as specified for the mating female contact style, and follow electrostatic discharge (ESD) precautions when handling connectors and mating devices. Ensure the mating male plug matches the 25-pin D-sub standard and that mounting clearances correspond to the connector's external dimensions.
