Amphenol Industrial AT04-12PB-P021 Automotive Connector Male, 12 Way, 78A, Crimp, Cable Mount, IP67

The Amphenol Industrial AT04-12PB-P021 is a high-performance 12-way male automotive connector engineered to withstand demanding environments in vehicle electrical systems. Featuring a secure crimp termination, this connector is ideal for providing reliable and high-current cable-to-cable connections.

Constructed from durable thermoplastic, the housing offers robust mechanical protection and long-term reliability. The design incorporates an integrated latch for positive mating and a wedgelock that verifies proper contact alignment and retention, reducing the risks of connection failure due to vibration or harsh operating conditions.

The AT04-12PB-P021 supports up to 78A of current and is equipped with nickel-plated copper alloy contacts for excellent electrical conductivity and corrosion resistance. The two-row configuration allows for compact installation, making it suitable for automotive, heavy-duty transportation, alternative energy, marine, military, diagnostic, and agricultural applications where space and reliability are critical.

Its IP67 protection rating means the connector provides a watertight seal under temporary immersion, and complete resistance to dust ingress, fulfilling harsh environmental sealing needs. The connector operates over a wide temperature range of -55°C to 125°C, making it appropriate for under-the-hood and exposed outdoor installations.

Compatible with standard AT Series plugs as well as other industry-standard interfaces, this model enables flexible system integration. The black color and rectangular profile, together with a cable mount configuration, streamline installation in automotive harnesses and control modules.

This connector is RoHS compliant, supporting green and sustainable electrical designs. With its superior mechanical and environmental sealing, the AT04-12PB-P021 is a preferred solution for high-power automotive distribution blocks, bussed feedback assemblies, splice block or tap block configurations, and other mission-critical control systems.

Applications include electrical power distribution, sensor integration, engine compartments, and field equipment wiring in sectors such as industrial vehicles, agricultural machines, alternative energy, marine platforms, and diagnostic systems. The included contacts and wedgelock simplify assembly and ensure optimal electrical performance over the long term.
