The AT06-12SC is a 12-position heavy-duty thermoplastic connector from the Amphenol Sine Systems AT Series™ family, designed for industrial applications requiring robust environmental protection and reliable electrical connections. The connector features IP67, IP68, and IP69K ratings in mated condition, providing dust-tight sealing and water resistance up to 1 meter for 24 hours (IP68) or high-pressure waterproof protection at multiple angles (IP69K). It incorporates an integral latching system that ensures definitive electrical and mechanical connection, with contact retention of 25 lbs minimum pull-out force and connector retention rated at 25 lbs per contact up to a maximum of 100 lbs. The connector demonstrates excellent mechanical durability, withstanding 50 g shock loads across all three axes without latch disengagement, vibration up to 20 g's at sine sweep frequencies of 10–2000 Hz, and thermal cycling from -55°C to +125°C for 10 cycles without cracking or damage. This connector is ideal for harsh industrial environments, mobile equipment, and applications demanding superior environmental seals and long-term reliability.
