M50-4803345

Headers, Male Pins Overview

The M50-4803345 is a 66-position right-angle pin header from the Harwin Archer M50 series. It features a 1.27mm (0.050 inch) mating pitch and utilizes a two-row configuration for board-to-board connections. The connector employs through-hole termination with solder joints and incorporates a push-pull fastening mechanism to secure mating interfaces. Contacts are constructed from copper alloy with gold plating, ensuring reliable conductivity. The housing is made of black liquid crystal polymer (LCP), providing high thermal stability and UL94 V-0 flammability rating. Rated current is 1A per contact, supporting operation within a temperature range of -40°C to 105°C.
