81036-500303-RB

Headers, Male Pins Overview

The 3M part number 81036-500303-RB is a rectangular header connector from the 810 series, designed for board-to-cable or wire applications. It features a right-angle through-hole mounting style with 36 positions arranged in two rows. The connector utilizes a 1.27mm (0.050 inch) mating pitch and a 2.54mm (0.100 inch) row spacing. Constructed with liquid crystal polymer (LCP) insulation rated UL94 V-0, it includes a four-wall shielded housing. The contacts are copper alloy pins with gold plating on the mating interface and tin plating on the tail, ensuring reliable soldering. Rated for -55°C to 105°C operation, it supports a current of 0.75A.
