Pilz PNOZ - The Optimum Safety Solution For
Each Requirement

The safety relays PNOZ monitor safety functions such as emergency stop, safety gates, light barriers, light curtains, two-hand controls, speed, standstill and much more besides. Everyday, PNOZ safety relays prove themselves in millions of applications worldwide.

In 1987 Pilz patented the first emergency stop relay to protect man and machine. That was a milestone in safety technology. The safety relays PNOZ quickly progressed to be the world's most commonly used safety relays. The PNOZ brand is now synonymous with safety relays. PNOZ - The original!

Continuous further development has led from simple devices to the modular safety relay myPNOZ and the configurable small controller PNOZmulti, the global safety standard for machines.

Count On The Standard In Safety Technology - Your Benefits

  • International certification
  • High plant availability and short downtimes thanks to convenient diagnostic options on the device
  • Faster commissioning and simple wiring through units with plug-in terminals
  • Complete solutions comprising evaluation devices compatible sensor technology and control and signal devices
  • Maximum safety, up to performance level "e" of EN ISO 13849-1 and SIL CL 3 of IEC 62061

Decision Making Support: How To Find The Right Safety Relay!

The modular safety relay myPNOZ is easy to operate, individually pre-assembled and therefore easy to install, so it complements our existing range of safety relays. But when do you use myPNOZ and when might PNOZsigma be the right choice?

myPNOZ is the ideal solution if you:

  • Have to monitor up to 16 safe inputs in your plant
  • Need a safety solution individually coordinated to you application
  • Want to implement both AND and OR links
  • Don't have time to learn to use a new software
  • Are looking for a space-saving solution for your control cabinet
  • Also have to flexibly exchange modules following commissioning

If you only need to monitor one individual safety function such as an emergency stop, we recommend our classic safety relays PNOZsigma or PNOZ X.

If you have to monitor more than 16 safety inputs in a more complex way and need comprehensive diagnostics, its recommended to use the configurable small controllers PNOZmulti. They can be freely configured using the configurator.

Save Costs With Push In Technology

The unit types with push-in technology offer a great advantage in terms of both economy and safety. They help you to cut costs due to short commissioning and service times.

Easy To Service Through Simple Operation

Connection of all commercially available cables with or without wire-end ferrule with quick and easy wiring. Double connection option per pole; can be opened individually or both at the same time which is beneficial when installing or changing the wiring and saves costs when replacing devices due to not requiring any rewiring so potential wiring errors during rewiring are eliminated. Coded plugs allow for easy and unmistakeable installation and increased handling safety during servicing. Maintenance-free due to defined clamping force; unlike screw terminals, no need to retighten regularly; therefore no follow-up costs due to retightening of terminals.

The Optimum Safety Relay For Every Application

In addition to the classic E-STOP function, the safety relays now monitor safety gates, light barriers, two-hand controls, pressure sensitive mats, muting, standstill and many other safety functions.
