Pressure sensitive safety mat and sensing edges must be wired into a controller
to monitor for actuation and proper functioning. The controller provides
the interface with the machine, robot or door controls. When the safety
mat or sensing edge controller registers a sensor actuation or fault, a
stop or reverse signal is sent to the equipment controls.
Safety mats and sensing edges used in machinery and robot guarding applications
are considered category 3 applications, requiring an ESD3 controller. Other
controller selections should only be made based on your application risk
assessment.
Risk categories are defined in EN 954, Safety of Machinery - Safety Related
Parts of Control Systems.
