77311-124-02LF Description

Short technical summary and product information.

The 77311-124-02LF is a 2-position unshrouded male pin header manufactured by Amphenol ICC. This connector features a single row of square pins with a 2.54mm pitch, making it suitable for board-to-board and wire-to-board applications. The header is designed for through-hole mounting with solder termination, providing a reliable mechanical and electrical connection.

 

Key specifications include a current rating of 3A per contact, an operating temperature range of -65°C to 125°C, and UL94 V-0 flammability rated thermoplastic insulation. The contacts are made of phosphor bronze with a tin finish (30µin thickness), ensuring good conductivity and corrosion resistance.

 

The unshrouded design allows for easy mating with standard female socket connectors. The black insulation body has a height of 2.54mm, and the overall contact length is 0.480 inches (12.19mm). With a push-pull fastening type, this header is ideal for applications requiring a low-profile, low-insertion-force connection.

 

This header is commonly used in various electronic devices, industrial controls, and consumer electronics where reliable connectivity is required. The part is RoHS3 compliant and REACH unaffected, meeting environmental standards for global use.
