BL 4 38 Z

Headers, Receptacles, Female Sockets Overview

The BL 4 38 Z is a 38-position header connector manufactured by Fischer Elektronik. It features a 0.100 inch (2.54mm) pitch and utilizes through-hole mounting for secure PCB attachment. The contacts are finished with tin plating to ensure reliable conductivity. The insulating body is constructed from PPS material, providing thermal stability within a -40°C to +200°C operating range and meeting UL 94 V-0 flammability standards. This component employs a stamped contact spring design with fork contacts.

Headers, Receptacles, Female Sockets Feature Summary

• Stamped contact spring design with fork contacts for precise electrical connections
• Insulating body made of PPS material ensuring high thermal resistance
• Tin-plated contacts for reliable signal transmission
• Through-hole installation method for robust mechanical support

Headers, Receptacles, Female Sockets Applications

• General electronic assemblies requiring header connections
• Industrial control systems utilizing standard pin spacing
• Equipment needing reliable through-hole interconnects

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix matches the required contact count and termination style. Confirm that the tin plating specification aligns with your environmental requirements. Ensure the through-hole footprint on your PCB layout corresponds exactly to the 2.54mm pitch dimensions provided in the official datasheet before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 38-position male header is required with through-hole termination. The tin finish is suitable for general applications where gold plating is not strictly necessary. Consider the PPS body material if higher temperature resistance than standard materials is needed. Verify that the fork contact design meets the mating connector requirements for your specific assembly.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the BL series of connectors from Fischer Elektronik, which focuses on stamped contact spring designs. The BL 4 38 Z specifically denotes a 38-position variant within this family. It serves as a standard interconnect solution for board-to-wire or board-to-board applications where reliable, cost-effective connections are prioritized over premium surface finishes.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must maintain the 38-position count, 2.54mm pitch, and through-hole mounting type. Verify that any alternative part uses compatible tin-plated contacts and PPS insulation. Check that the fork contact geometry matches existing mating components to ensure proper engagement without modification.
