ATEX plug and socket

15A~200A YT / GZ / YZ series of non-spark electric connectors can  be applied to electrical connection for petroleum exploration, drilling  electric control and other electric apparatuses. Accord with IEC 60079-15:2005<Electrical apparatus for explosive gas atmospheres - Part 15: Construction, test and marking of type of protection "n" electrical apparatus> and Chinese standard GB3836.8-2003, And obtained the ATEX certificate in Europe, No.: CE0470 Nemko 07ATEX3202.

The electric connector consists of two parts: Plug and socket, of which the plug is mobile (YT). There are two types of socket: Panel- fixed (GZ) and panel-mobile (YZ). Coupling way of the plug and socket is spiral bayonet snap coupling. End connection form between the contacts and wires is crimping. The contacts use elastic rim to support positioning and are the structure of installing from the rear and removing from the front.

The connector case is aluminum die casting alloy. The contact is coated with silver, which is contacted reliably, connected conveniently, has better tightness and insulation, and has of water-proofing, dirt-proofing and vibration-proofing features.

The explosion-proof mark is ExnA II T4.
