Amphenol Amphe-Coal EX Hazardous-Rated ConnectorsAmphenol Industrial Products Group now offers an explosion-proof, heavy-duty hazardous-rated connector series that provides outstanding performance in automated process control and instrumentation systems. The Amphe-Coal EX is a miniature version of Amphenol’s Amphe-Mine EX connector series.

Made up of environmentally sealed plugs and receptacles, the Amphe-Coal EX series is certified for use in IECEx Group 1 – mining in Australia, and is going through MA mining certification in China.

In the mining industry, this connector series is ideal for use in classified facilities like underground mining sites where machinery requires more power and signal in a smaller interface.

Amphenol’s Amphe-Coal EX series provides a reliable connection in power distribution, data acquisition and transmission, communication systems, and process control as well as in embedded computer and other applications where zone- or class-rated connectors are required.

These compact, environmental connectors offer exceptional mating properties and come in high-grade 316 stainless steel. The Group I shell is only offered in stainless steel, while Group II and Group III come in stainless steel, aluminum, or brass. Shell sizes include 9, 11, 13, 15, 17, and 19.

In addition to its full range of hardware styles, including the use of flameproof-rated cable glands, the Amphe-Coal EX series features high-quality copper contacts with silver plating (gold plating is also available as an option).

The Amphe-Coal EX offers high amperage up to 217A at 1,250VDC and 900VAC as well as a broad range of inserts ranging between two and 79 contacts. The unit’s plug and socket, when connected together, are mechanically interlocked by means of a threaded nut retained by a locking set screw.
