Use the “key in pocket” maintenance safeguarding system to protect your staff from the hazards of an unplanned restart of plant and machinery in maintenance situations. This solution guarantees that hazardous plants cannot be put back into operation while there are people in the danger zone.
This is how it works: operators authenticate themselves on the safety gate via PITreader, using a personal transponder key. A security ID is stored in a safe list in the Pilz controller (PNOZmulti 2 or PSS 4000). When the machine has stopped, it can be accessed to carry out work. The staff member retains the transponder (“Key-in-pocket”). After leaving the plant, everyone must log off via the PITreader to put the plant back into operation. As a result, the security IDs are removed from the safe list. If the list is empty, the machine is enabled and can be put back into operation.
PILZ will present this new solution in detail at SPS in Nuremberg. Do you have your ticket already?

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.
