Compact Explosion-Proof Circular Connector Series from Amphenol

Amphe-Coal EX ideal for use in the mining industry

Amphenol Industrial Products Group, a global leader in interconnect systems, has introduced Amphe-Coal EX, a series of explosion-proof, heavy duty hazardous rated connector that provides outstanding performance in automated process control and instrumentation systems. The New connector is a miniature version of the company’s Amphe-Mine EX connector series.

Manufactured from environmentally sealed plugs and receptacles, Amphe-Coal EX is certified for use in IECEx Group 1 – mining in Australia, and is going through MA, mining certification in China.  When utilised in the mining industry, this connector series is ideal for classified facilities like underground mining sites where machinery requires more power and signal in a smaller interface. It provides a reliable connection in power distribution, data acquisition and transmission, communication systems, 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 1 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 flameproof rated cable glands, the Amphe-Coal EX series features high quality copper contacts with silver plating (with gold plating available as an option).

Amphe-Coal EX has a high amperage up to 217 amps at 1,250 V/DC and 900 V/AC as well as a broad range of inserts ranging between 2 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.
