AT04-12PA-SR2GY is a 12-position receptacle connector from Amphenol Sine Systems' AT Series SR02 extended strain relief line, designed for high-performance industrial applications. The connector features a reduced diameter rear seal (green) with SR02 strain relief, which protects each individual wire cavity to maximize sealing integrity and maintain proper wire routing regardless of wire bundle direction or improper installation. It accepts all A Series Size 16 contacts and maintains IP68/69K rated (mated) performance. The grey body with keyed A configuration ensures proper mating alignment and prevents incorrect connections. This connector is ideal for industrial environments requiring robust, cost-effective solutions with thermoplastic construction and extended strain relief wire cavities that eliminate stress on the rear seal.
