BL 2 28 G

Headers, Receptacles, Female Sockets Overview

The BL 2 28 G is a 28-position through-hole header connector manufactured by Fischer Elektronik. It features a stamped contact spring with a fork contact design and a separable pitch of 0.635 mm (0.100 inches). The contacts are gold-plated, utilizing a Ni+≥0.2µm Au surface finish over a CuSn-alloy base material. The component supports a nominal current of 1.5 A and a nominal voltage of 125 V AC, with a test voltage rating of 1500 V. It operates within a temperature range of -40°C to +200°C and withstands soldering at 260°C for 10 seconds.

Headers, Receptacles, Female Sockets Feature Summary

• Fork contact design engineered for precise 0.635 mm separable pitch alignment
• Gold-plated contact surfaces ensuring reliable electrical connectivity and corrosion resistance
• Robust stamped contact spring construction for secure mechanical retention

Headers, Receptacles, Female Sockets Applications

• Through-hole PCB interconnection systems requiring high density
• Signal routing in electronic assemblies operating up to 125 V AC
• Industrial control modules demanding stable connections under thermal stress

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix matches the required contact plating and pin count configuration. Confirm that the 0.635 mm pitch aligns with the target board layout and mating connector specifications. Ensure the through-hole footprint dimensions correspond precisely to the manufacturer's recommended land pattern to guarantee proper solder joint integrity and mechanical stability during assembly processes.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a 28-position female header with a 0.635 mm pitch is required for through-hole mounting. The gold plating option is suitable for applications prioritizing low contact resistance and long-term reliability. Consider the 1.5 A current rating and 125 V voltage limit against the system requirements. Verify compatibility with mating male pins designed for the fork contact geometry to ensure optimal engagement force and signal transmission quality.

Headers, Receptacles, Female Sockets Part Context

The BL 2 series represents Fischer Elektronik's line of stamped contact spring headers. These components are designed for high-density PCB connections, offering various pin counts and plating options. The BL 2 28 G specifically provides a 28-position configuration, fitting into the broader family of connectors used for reliable signal and power distribution in compact electronic designs.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other 28-position, 0.635 mm pitch through-hole headers with gold plating. Verify identical mechanical dimensions, current ratings, and fork contact compatibility before substitution. Alternative part numbers from the same manufacturer may offer different plating or housing materials but must match the critical interface specifications.
