The AT04-12PB-P027 is a 12-position HYPERBUSS™ AT series bussed receptacle connector designed for high-performance power distribution and signal interconnect applications. This connector features a thermoplastic housing with copper alloy contacts (nickel or gold plated) and supports a maximum current rating of 13A per contact, with the total buss current limited to 13A across all positions. The connector is rated IP67 in mated condition, providing superior environmental sealing for industrial applications, and operates reliably across a temperature range of -55°C to +125°C. The AT04-12PB-P027 is configured with Key B keying and black color coding, and mates with AT06 series plugs. This connector is ideal for industrial power distribution systems, battery management systems, and chassis grounding applications where robust, bussed electrical pathways are required.
