PILZ Safety relay / safety relays PNOZ

The aim of Pilz relays is to keep the risk to man and machine as low as possible. To guarantee this protection, Pilz has for decades been developing innovative safety relays which have been proven on the market a million times over

The safety relays PNOZ monitor safety functions such as E-STOP, safety gates, light barriers, light grids, two-hand controls, pressure sensitive mats, speed, standstill and much more too. Every day, PNOZ safety relays prove themselves in millions of applications worldwide.
