Hartland Controls' relays provide power system on/off switching capabilities. The primary purpose of Hartland Controls/Littelfuse's relays is to switch electrical circuits on and off in an instant. Relays are essentially electromagnetic switches activated by a low power signal or current in one circuit to open or close another circuit. They are most commonly used in power system networks and multiple automotive and industrial applications or HVAC where the system is controlled by 24 VAC, 120 VAC, or 240 VAC.

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.
