AT04-4P-SR01BLK is a 4-position receptacle connector from Amphenol Sine Systems' AT Series SR01 extended strain relief line, designed for high-performance industrial applications. The connector features a standard diameter rear seal (red) with specifically-designed extended strain relief wire cavities that protect each individual wire seal and eliminate stress on the rear seal while maintaining IP68/69K rated (mated) performance regardless of wire bundle direction or improper installation. It accepts all A Series Size 16 contacts and operates at 13A current rating, with a thermoplastic black body construction. The extended strain relief design maintains proper wire routing 100% of the time, making it ideal for demanding industrial environments where sealing integrity and wire protection are critical, such as automotive, heavy equipment, and industrial automation applications.
