BL LP 4 48 S

Headers, Receptacles, Female Sockets Overview

The BL LP 4 48 S is a precision-engineered male header connector manufactured by Fischer Elektronik. It features 48 positions with a 0.100 inch (2.54 mm) pitch, designed for through-hole mounting on printed circuit boards. The connector utilizes an insulating body made of PPS material, which supports a temperature range from -40°C to +200°C and meets UL 94 V-0 flammability standards. Contacts are constructed from CuSn alloy and feature selective gold plating over a nickel underlayer, ensuring reliable electrical performance in low-profile electronic assemblies.
