A79639-001

Headers, Receptacles, Female Sockets Overview

The A79639-001 is a Polarized Nano (PZN) series connector header manufactured by Omnetics. It features 18 positions in a single row with a 0.025-inch (0.64mm) mating pitch and 0.040-inch (1.02mm) row spacing. Designed for through-hole straight termination, this male pin connector utilizes gold-plated contacts with a 50.0µin thickness on the mating interface. The housing is made of natural thermoplastic insulation, supporting a rated current of 1A per contact across an operating temperature range of -55°C to 125°C.
