Industrial connectors for explosion-proof applications
Harting’s Han Ex industrial connector portfolio are designed for explosion proof applications and feature a series of five size 3A sets. Each set is comprised of a hood, housing, and high pin count insert. This Han Ex set is for exclusive use in intrinsically safe circuits of categories "ia", "ib" and "ic" of explosion protection method "Ex i," and is suitable for Zones 0, 1 and 2 for gas and Zones 20, 21 and 22 for dust. The "Ex i" protection method assures intrinsically safe electrical circuitry that is limited for maximum voltage, current, capacity and inductance. The Han Ex housing’s blue color indicates that an intrinsically safe circuit is present.
Harting’s Han Ex sets are available with 4, 7, 8, or 12 contacts. There are three variants with crimp termination and two with Harting’s proprietary Han-Quick Lock termination technology. The Han Ex portfolio is suitable for a wide range of applications where the substance being processed or transported is potentially explosive or combustible. These include gases, liquid and solids in the chemical and mining industries, grains and sugars in the food sector, alcohol and dust in pharmaceuticals, fermentation gases in wage management, thermal fuels in power generation—even biogas plants on farms.
