AT04-4P-RD01 is a 4-position AT Series™ heavy-duty multi-pin thermoplastic connector designed for industrial applications requiring robust environmental sealing. The connector features an IP68 and IP69K rating in mated condition, an integrated latching system for definitive electrical and mechanical connection, and a thermoplastic UL94-VO housing with superior environmental seal retention. It operates across a temperature range of -55°C to +125°C with a maximum voltage rating of 250V and supports 13A current capacity with Size 16 contacts. The connector incorporates stamped and formed copper alloy contacts with nickel plating, silicone rubber sealing material, and demonstrates excellent fluid resistance to gas, oil, mineral oil, acid bath, and basic bath environments. These connectors are ideal for heavy-duty industrial interconnect applications where environmental protection, reliability, and mechanical durability are critical requirements.
