BLM 3 SMD 4 G

Headers, Receptacles, Female Sockets Overview

The BLM 3 SMD 4 G is a surface-mount male PCB connector manufactured by Fischer Elektronik. It features four contacts with a 1.27 mm pitch, designed for board-to-board interconnections. The contacts are constructed from a CuSn-alloy and feature gold plating on the mating surface. The contact sleeves utilize a nickel layer of at least 0.2 micrometers followed by gold, while the internal spring mechanism incorporates a nickel layer of 46 micrometers combined with tin. This component supports reliable electrical connections in compact electronic assemblies.
