RS Components has extended its range of interconnection solutions serving industries such as mining, chemicals, process automation, and oil and gas, with the addition of HARTING Han Ex connectors for use in potentially explosive environments. Han Ex connectors meet the intrinsic safety requirements of CENELEC equipment codes ia, ib and ic, allowing use in explosion zones 0, 1 and 2 , zones 1 and 2, or zone 2 respectively.

The connectors comply with DIN EN 60 079-0 and DIN EN 60 079-11 standards, and are T6 temperature classified for use where ignition hazard exists at temperatures as low as 85°C.

The Han Ex connector range comprises a set of hoods, housings and inserts designed as a system to satisfy intrinsically safe applications. HARTING’s patented vibration-proof Han-Quick Lock® termination technology allows fast and easy assembly without special tools.

Alternatively, crimp terminations are available, which can be used with wire gauges down to AWG 26. The inserts have greater than 10GΩ insulation resistance, and housings are powder coated in the standard blue colour used to indicate an intrinsically safe circuit.

All the connectors ensure IP65 ingress protection when mated, and are specified for operation in ambient temperatures from -20°C to 40°C. The full Han Ex range, comprising variants with 4, 7, 8, or 12 contacts, is available now from RS Components.
