sensor PRO Emergency Stops


Emergency stop buttons of the SNH series are used on or near machines for the protection of persons. They serve the purpose of switching off / stopping machines and systems to avoid or reduce emerging or existing hazards to persons. Emergency stop buttons of the SNH series are also used to avoid damage to the machine or working material.

Wieland's SNH series of emergency stop operators include illuminated, IP69K, key lock options and many more. Their modular design permits various actuating elements to be freely combined with the chosen contact design.

Failure protection

The emergency stop buttons of the SNH series have a special failure protection mechanism that automatically detects when a contact block is removed from the respective actuating element and then switches off safely. This is a great way to reduce the frequency of e-stop function tests. It also greatly improves the reliability and safety of the e-stop button with minimal additional costs.
