Operating Principles

All our sensors have a common purpose: to protect against collision or pinch hazards arising from automatically controlled movements. They do this based on different operation principles however, depending on the context in which they are used.

Our classic Safety Mats, Safety Edges and Safety Bumpers work on the principle of pressure sensitivity, i.e. they respond to contact or loads.

Tactile sensors of the normally open type are based on two separate, conductive layers, a fixed distance apart. When the sensor is actuated - e.g. by stepping onto a Safety Mat - the contact is closed.

In the normally closed type, the tactile sensors have a chain of positive break contacts with a constant current flowing between them. In this case, the application of pressure causes the contact to be interrupted. In both cases, a signal is sent to the control system and the drive is immediately placed in a safe condition or switched off.

All Mayser tactile sensors are monitored for function based on the closed-circuit current principle. Thanks to their simple design, tactile sensors are robust, reliable and unaffected by environmental influences such as dust, light, temperature or humidity.
