A79648-001

Headers, Receptacles, Female Sockets Overview

The A79648-001 is a Polarized Nano connector header manufactured by Omnetics. It features a surface mount, right-angle installation style with 22 positions arranged in two rows. The connector utilizes a 0.025-inch (0.64mm) mating pitch and a 0.040-inch (1.02mm) row spacing. Contact materials include beryllium copper and copper alloy, with gold plating on the mating surfaces. Rated current is 1A per contact, operating within a temperature range of -55°C to 125°C.
