By the use of safety mats hazardous machine areas can be protected to ensure the safety of persons. Safety mats operate according the guidelines of DIN EN 292-1. When stepped on, the safety mat will make sure that the power source will be switched off immediatley. As long as a person stays on the mat, the machine cannot be set back into operation. Safety mats have a NC (normally closed) contact, and therefore, unlike other products in the market, needs no special control unit for switching!
