By Press release

Montreal, QC, March 2015 – HARTING has launched the Han® Ex industrial connector portfolio for explosion proof applications with a series of five size 3A sets, each comprised of a hood, housing and high pin count insert. This first Han® Ex rollout is for use exclusively 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 colour 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. Other variants are available on request.

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 waste management, thermal fuels in power generation – even biogas plants on farms.


The HARTING Technology Group, family owned and based in Germany, employs more than 4,000 people globally with subsidiaries and branch offices in 40 countries. With production facilities in Europe, Asia and the United States, the HARTING portfolio of connectivity solutions focuses on multiple levels, from the machine to the device and into the communication infrastructure. The U.S. facility in Elgin, Illinois is one of three HARTING locations that manufactures the HIS product line (HARTING Integrated Solutions – backplanes) and custom cable assemblies. The company’s core business is intelligent and high-performance connection technology. HARTING works in almost all industrial markets with a focus on requirements for robust, reliable connectivity solutions.
