AT16-18SC-SR02 is an 18-position heavy-duty multi-pin thermoplastic connector featuring integrated SR02 strain relief that protects each wire cavity to maximize sealing integrity. The connector is rated for 13A maximum current at 250V and accommodates Size 16 contacts (14-20 AWG wire range) with copper alloy, nickel-plated contacts and optional gold plating. It provides IP68/IP69K environmental sealing in mated condition with silicone rubber seals, thermoplastic housing with integrated latch for mating, and operates reliably across -55°C to +125°C. The connector delivers superior front and rear environmental seals with a multi-sealing perimeter against environmental ingress, achieving over 100 mating cycles with 1000 megohms minimum insulation resistance and dielectric withstanding voltage of 1500V AC. Ideal for heavy-duty, transportation, marine, diagnostic, alternative energy, and agricultural interconnect applications requiring robust environmental protection and mechanical durability.
