EFB Elektronik 28661.1 D-Sub 25-pin Connector Grey Tinplate

The EFB Elektronik 28661.1 is a professional-grade 25-pin D-Sub connector engineered for stable and reliable data and signal transmission. Built with a robust tinplate housing, this connector offers excellent mechanical protection and electrical shielding, making it a dependable choice for electronics assembly, custom cable manufacturing, and industrial interface applications. Its neutral grey design ensures it integrates seamlessly into standard hardware setups while maintaining high signal integrity.

Advantages

This connector stands out due to its durable construction which provides long-term resistance to environmental stressors. The tin-plated housing not only enhances the structural integrity of the component but also contributes to better grounding and shielding properties. With a quality level supporting at least 50 mating cycles, it is designed to withstand repeated connections and disconnections, ensuring consistent performance in professional and industrial environments.

Suitable for

• Custom serial cable assembly
• Industrial automation and control interfaces
• Computing hardware and peripheral connections
• Prototyping and electronics repair

When it may not be suitable

This connector is not intended for high-vibration environments where locking hardware is strictly required, as it lacks integrated screw-locking mechanisms. It is also not suitable for applications requiring high-speed data transmission beyond the standard capabilities of D-Sub interfaces or for outdoor use without additional protective housing.

Key specifications

• Connector type: D-Sub 25-pin
• Housing material: Tin-plated steel
• Durability: Minimum 50 mating cycles
• Color: Grey

How to use

To use the EFB Elektronik 28661.1, prepare your multi-core cable by stripping the outer jacket and individual wire insulation. Solder the wires to the corresponding pins on the connector, ensuring that each connection is secure and properly insulated to prevent short circuits. Once the wiring is complete, the connector can be housed in a compatible D-Sub backshell to provide strain relief and additional protection before being plugged into the target device port.

What to consider before purchase

• Verify the pin count matches your specific interface requirements
• Ensure you have the appropriate soldering equipment for D-Sub termination
• Check if a backshell or hood is needed for your specific cable assembly

Usage recommendations

For optimal signal quality and longevity, ensure that all solder joints are clean and free of cold solder defects. Always use a compatible backshell to protect the termination points from mechanical strain and external interference.
