Connectors for Hazardous Areas

Jan. 22, 2018
HARTING’s Han Ex connector series have been certified to the National Electric Code’s NEC 500 standard for use in Class I, Division II hazardous locations, making them available for use across North America.

An alternative to hard-wiring electrical connections, the connectors are suitable for applications in the oil and gas, mining and chemical industries and in process automation. Compared to hard-wiring electrical circuits, they increase installation speed and safety while reducing downtime for maintenance downtime and trouble-shooting. All connectors in the series offer IP65/67 protection class in the mated position. Inserts and housings are available for sizes 3A to 48B. Their contact inserts provide a high number of poles while meeting the standards of the ignition protection class even in the tightest spaces. For example, up to 24 contacts can be located in the size 24B housing. Crimp and screw terminals as well as the company’s proprietary fast connection technology, Han-Quick Lock, can be used for creating connections. Housings are equipped with cable outlets for thread sizes M20 to M40. Metal locking levers lock the connectors and can be released only with a tool, preventing opening by accident in an explosive atmosphere. Their blue color makes for easy identification of inherently safe circuits.
