AT16-18PE-PM11 is an 18-position receptacle connector with pin contacts designed for heavy-duty industrial applications. It features a thermoplastic housing with an integrated latch for mating, silicone rubber sealing material, and Size 16 contacts (14-20 AWG) with copper alloy construction and nickel plating. The connector operates over a temperature range of -55°C to +125°C and achieves IP68/IP69K environmental sealing in mated condition, with a maximum current rating of 13A at 250V. It demonstrates superior durability with over 100 mating cycles, shock resistance of 50 g's in three axes, and vibration tolerance up to 20 g's at sine sweep frequencies of 10-2000 Hz. The PanelMate™ AT option provides panel-mount capability, making it ideal for transportation, marine, diagnostic, and alternative energy applications requiring reliable multi-pin interconnection.
