BL 4 70 Z

Headers, Receptacles, Female Sockets Overview

The BL 4 70 Z is a 70-position through-hole header connector manufactured by Fischer Elektronik. It features a 0.100 inch (2.54 mm) pitch and utilizes tin-plated contacts for reliable conductivity. The insulating body is constructed from PPS material, ensuring stability across a temperature range of -40°C to +200°C, with brief exposure up to 260°C for 10 seconds. The component meets UL 94 V-0 flammability standards and supports a test voltage of 1500 V.

Headers, Receptacles, Female Sockets Feature Summary

• Stamped contact spring design with fork contact geometry for secure mating
• PPS insulating body providing high thermal resistance and dimensional stability
• Tin surface finish on contacts to ensure consistent electrical performance

Headers, Receptacles, Female Sockets Applications

• General electronic interconnections requiring through-hole mounting
• Industrial control systems operating within specified thermal limits
• Consumer electronics assemblies utilizing standard 2.54 mm spacing

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count matches the required 70 positions before integration. Confirm that the tin plating specification aligns with corrosion resistance requirements for the target environment. Ensure the PCB footprint accommodates the 2.54 mm pitch without interference. Check that the assembly process respects the maximum peak soldering temperature of 260°C for ten seconds to prevent thermal damage to the PPS housing.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-density 70-pin connection is necessary in a through-hole application. The 2.54 mm pitch offers compatibility with standard board layouts. The PPS material choice is critical for applications involving elevated temperatures or strict flammability regulations. Consider the fork contact design for its specific mechanical engagement characteristics compared to other spring types.
