AutomationDirect has added SSP safety enabling switches, also known as “hold-to-run” or “dead man’s” switches. When used in conjunction with a properly designed safety system, they provide the operator with a special control mode for tasks such as maintenance or debugging of hazardous equipment.
These switches consist of a spring-return three-position (N.O.-N.C.-N.O.) grip button that must be maintained by the operator in the middle position for the machinery to continue operating.
In addition to the grip button, models are available that include a built-in E-stop button, LED indicators, additional pushbuttons for auxiliary functions, or an activity sensor to detect when the switch is in its home position. All models come in a rugged IP67 enclosure and are easy to use even with gloved hands.
The new SSP safety enabling switches and accessories start at $219.00 and come with a one-year warranty.

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.
