Safety mat relays

Safety or pressure mats operate as a lone safety device with N/O rather than positive-guided contacts. For this reason, safety mats are mainly used as a protection against circumvention. This means that the border to the safety area is monitored using an ESPE and the area beyond that via a safety mat.
