A79644-001

Headers, Receptacles, Female Sockets Overview

The Omnetics A79644-001 is a Polarized Nano Series connector header featuring 20 positions in a single row. It utilizes a 0.025 inch (0.64 mm) mating pitch with a 0.030 inch (0.76 mm) row spacing. Designed for through-hole vertical termination, this component employs male pin contacts with gold plating and a natural thermoplastic insulator. The assembly includes guide pins for precise alignment and supports a rated current of 1A per contact within an operating temperature range of -55°C to 125°C.
