The VariaPro line of Cable Glands is made for enduring extremes. It could be hot, cold, or acid the VariaPro line is ready. These are the cable glands for particularly extreme requirements. Each of the three varieties of the Varia Line: Varia Pro, Varia Temp, Varia Chem, has its own area of expertise. The standard VariaPro it was designed for the demanding needs of the European Rail but also can be used in most standard applications.
The PRO has very high fire protection requirements (DIN EN 45545-2 and 45545-3) and can withstand flames for 30 minutes with its EPDM Seal. All of the VariaPro’s are made out of Nickel-plated brass with protection class of IP 68 – 10 bar with Metric threading.
The VariaPro TEMP is made for applications as cold as the artic circle (-60° C or -76° F) or heat extreme (200° C or 392° F) with its VMQ (silicone) Seal. Making the VariaPro TEMP well suited for applications in refrigeration, industrial ovens or steel and metal industry.
The VariaPro CHEM is aimed at sectors of the processing industry and is particularly resistant to acids and chemicals with its FKM Seal. The CHEM is well suited for applications in the pharmaceutical, biotechnology or chemical industries.
Additional features for all the VariaPro Line include a molded seal for integrated EMC protection. The VariaPro cable glands also have an anti-twist protection, ensures that the cable and molded seal do not twist during installation, thus loose their seal. The VariaPro also has low profile, helping to save space in tight applications.

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
