BL 4 44 G

Headers, Receptacles, Female Sockets Overview

The BL 4 44 G is a stamped contact spring from Fischer Elektronik, engineered for precise and reliable electrical connections. It features a fork contact design suitable for specific mating requirements. The component utilizes a CuSn-alloy contact material with a gold-plated surface finish to ensure durability and conductivity. The contact surface specification includes Ni+≥0.2µm Au plating, while the contact sleeve offers Ni+46µm Sn protection. This internal spring type is designed for secure integration in electronic assemblies requiring stable signal or power transmission.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the exact physical dimensions and mating compatibility before procurement. Confirm that the gold plating thickness meets the specific application's wear resistance requirements. Ensure the CuSn-alloy composition aligns with environmental compliance standards. Cross-reference the fork contact geometry with the intended counterpart connector to guarantee mechanical fit and electrical continuity.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a stamped spring contact with a fork interface is required. Consider the gold plating for corrosion resistance in demanding environments. Evaluate the CuSn-alloy properties against mechanical stress expectations. Ensure the internal spring mechanism supports the necessary insertion and withdrawal cycles for the target application lifecycle.

Headers, Receptacles, Female Sockets Part Context

This part belongs to Fischer Elektronik's range of stamped contact springs. It is distinct from header connectors like the SL series or heat sinks like the SK series found in broader catalogs. The BL 4 designation indicates a specific spring contact family, differentiated by its fork design and alloy composition rather than pin count or board-mounting style.
