Safety contact mat
Contact mats are used on...
  • machines, plants and robotic systems where the areas of danger are unchecked accessed
  • plants where the presence of a person at a certain position is necessary
  • elevators, in order to prevent the unallowed entering of the elevator roof
  • building entrances

Safety Contact Mats are used for safeguarding areas of danger on machines and plants with the aim of preventing unchecked access. The switching mat can be individually adapted to the area which has to be secured. With the help of the closed-circuit-principle a constant monitoring of the safety contact edge is insured.
The safety contact mat correspond to the safety category prEN 1760-1

Functional description 
The STM safety contact-making mat is fitted with two two-core connecting cables and offers the possibility of connecting several mats in series up to a maximum total area of 10 m2. One end of the cable is connected to the evaluation electronics and the terminal resistance is connected to the other end (prepared accordingly at the factory). The electronics now monitor the entire conductor route, including the mats, through to the terminal resistance. The contact-making surfaces make contact in the event of external forces acting on the mat and the resistance is bridged. This immediately causes a signal within the electronics that is then given as a potential-free output for contact-making by the relay. The entire switching arrangement is monitored at the same time for cable rupture or manipulation.
simple assembly 
If the underground is to some extent flat, clean and free of from outside parts, the assembly is very simple and economical. It has to be merely made sure that the connection managements of the switching mat are transferred suitably for the mutual connection. All switching mats get connected to each other and the lines are transferred on the circulation edge of the switching mats. The circulation edge is attached around the area, it is made sure by what that all connection lines are led for certain. The underground is finally drilled and suitable fastening means to save the circulation edge are attached. The wiring of the switching mats to the end judging device is just as simple since only two connection wires are available for the complete system. Only a minimum of technical experiences is therefore required. An illustrated Operating instructins is available.
Safety Switchgear SK 41/32 
The single-channel SK 41-32 switchgear finds application in the evaluation of safety contact mats as well as in providing security of pinch and shear points caused by safety contact edges and safety bumpers. The switchgear is designed in accordance with EN 954-1 for Category 3. In order to meet Category 3 requirements, the switchgear has been
designed to be redundant, diversified, and equipped with two safety relays which query each other and are force guided. In order to permit the quiescent current of the circuit element to be monitored, a terminal resistor has been integrated in the signal transmitter. When
the desired quiescent current is flowing, the output relay is activated and the switching contact is closed. If the signal transmitter is activated or the safety circuit is interrupted, the relay switching contact opens. The switch states of the relays and the applied circuit voltage are indicated by LEDs.
