Han® connectors for explosive atmospheres meet US standards

Han® Ex connectors now meet the NEC 500 standard for the north American market.

From this spring, connectors will now be available in all sizes in the Han® Ex series for explosive atmospheres – meeting US standard NEC 500. These housings are permitted for use in Class I, Division II hazardous locations. This product range for the North American market includes inserts and housings from sizes 3A to 24B. Like all Han® Ex connectors, they ensure protection class IP65 when plugged in. Their blue colour is for easy identification of inherently safe circuits.

The Han® Ex series’ contact inserts provide a high number of poles in the smallest of spaces. Up to 24 contacts can be located in the size 24B housing, for example. Crimp and screw terminals as well as Han-Quick Lock® can be used for creating connections. Housings are equipped with cable outlets for thread sizes M20 to M40. Extremely robust metal locking levers are used to lock the connector and can only be released with a tool, preventing it from being opened by accident in an explosive atmosphere.

Compared to hardwiring, users of Han® Ex connectors can increase the flexibility of their application, reduce down-time to maintenance work and increase installation safety. This is particularly applicable for explosive atmospheres in the mining and chemical industries and process automation.
