HARTING says it has extended the Han® Ex intrinsically safe connector family with a number of new standard inserts and housings that offer users greater flexibility by providing additional contact numbers. The Han Ex range, which is deployed chiefly in the mining, chemistry and process automation industries, is designed to conform with the preconditions for the ignition protection intrinsic safety category, and can also be applied in the explosion endangered zones 1 and 2.

In intrinsically safe electrical circuits the power is limited so that, even if a spark occurs, it cannot ignite potentially explosive surroundings. The product portfolio offers new standard inserts and housings in the well-established HARTING sizes of 6 to 24B, and includes contact inserts offering a large number of contacts in a compact space. Up to 64 connections are possible in combination with a 24B housing. Crimp, screw and cage clamp connection technologies are all available. The housings offer cable outlets of M20 to M40, while a robust and reliable metal bracket serves as a locking system.

The housing alloy has been selected to enable applications in methane/coal-dust atmospheres. In addition, the connectors comply with the IP protection class 65 in the plugged state. The blue colouring of the housing is the standard indication for intrinsically safe electrical circuits.
