NSD Safety Mat System

Breakthrough NSD (New Switching Device) technology provides digital (on/off) switching for safety mat applications.

NSD safety mats are designed to be machine interfaced with only NSD safety relay controllers for normally open SPST 4-wire safety mats. Heavy-duty electrode assembly and durable outer shell provide excellent impact resilience and the ability to withstand heavy loads.

No rigid steel electrodes used in the switching mechanism that can rust and dent.  Mat flexibility prevents short outs, especially like those that occur in the corners of steel mats.  No rusting of the mat which prevents dead zones.

The NSD Safety Mat System safety relay controllers contain two independent control circuits which allow for shut down due to any single failure in one of the control circuits. The N.O. output circuit is controlled by two captive contact relays in series which are both monitored. If the contact in one relay should stick closed (i.e., contact weld), the other relay will shut down and the LED will indicate the fault; if the contact on the bad relay opens back up, you must reset the power to clear the fault. This relay contact monitoring provides a high degree of user safety.
