The AT16-18PB-PM11 is an 18-position receptacle connector with pin configuration, part of the AT Series™ heavy-duty multi-pin thermoplastic connector family designed for demanding industrial environments. It features Size 16 contacts (14-20 AWG wire range) with a maximum current rating of 13A at 250V, and is available with optional keying configurations and PanelMate™ AT mounting. The connector incorporates superior front and rear environmental seals with silicone rubber sealing material, achieving IP68/IP69K protection in mated condition, along with an integrated latch for definitive electrical and mechanical connection. Operating reliably across -55°C to +125°C with mating cycle durability exceeding 100 cycles, the connector delivers exceptional shock resistance (50 g's per axis) and vibration tolerance (20 g's maximum acceleration at 10-2000 Hz sine sweep). This connector is ideal for heavy-duty, transportation, marine, diagnostic, and alternative energy applications where robust interconnect performance and environmental protection are critical.
