AT16-18PB-SR02 is an 18-position receptacle pin connector from the AT Series™ product line, featuring heavy-duty thermoplastic construction with integrated latch for definitive electrical and mechanical connection. The connector accommodates Size 16 contacts (14-20 AWG wire range) with copper alloy, nickel-plated contacts and optional gold plating, delivering a maximum current rating of 13A at 250V. It incorporates optional SR02 strain relief that protects each wire cavity to maximize sealing integrity, combined with superior front and rear environmental seals providing IP68/IP69K protection in mated condition. The connector operates reliably across -55°C to +125°C, withstands 50 g shock in three axes, vibration up to 20 g's at 10-2000 Hz sine sweep, and maintains over 100 mating cycles with minimum 25 lbs terminal retention force. This design is ideal for heavy-duty, transportation, marine, diagnostic, alternative energy, and agricultural applications requiring robust environmental sealing and mechanical durability.
