Main Advantages
Easy to handle due to compact, lightweight design
Available in in-line and wall/panel mounted configurations
CSA and ATEX rated for use in Zones 1 and 2 (gas) and Zones 21 and 22 (dust)
 
DXN Series plugs and receptacles are convenient, lightweight devices that are safe for use in hazardous environments such as refineries or silos where exposure to flammable gas or dust is a concern. The DXN's compact size and durable construction makes them easy to handle and well suited for in-line connections of electrical equipment. When used to connect modular equipment, DXN's provide plug and play simplicity and help reduce costs by eliminating the need for expensive safety enclosures.
 
With DXN's installed, users can safely connect or disconnect equipment under full load in potentially explosive areas. The DXN's dead front construction assures electrical safety by preventing user access to live parts. IP66 + 67 ratings are achieved as soon as the plug and receptacle are mated, making them the perfect choice for wet or dusty environments.

DX Series plugs and receptacles are heavy duty metallic devices that are a good choice for refineries, petroleum platforms, chemical and pharmaceutical plants, grain silos and other locations where exposure to flammable gases and/or dusts is likely to occur. DX's are ATEX rated and they have also been tested and approved by ETL for operation under load in a gaseous environment (14.5% acetylene). This is one of the key performance tests required for UL Class 1, Division 1 explosion proof plugs and receptacles.
