The MatGuard safety mat is a pressure-sensitive safeguarding
product that is designed to detect the presence of people on its
sensing surface.
The MatGuard safety mat has two conductive hardened steel plates
that are held apart by non-conductive compressible separators.
Each four-wire mat, operating on only 24V DC, is pre-wired and
connected in series with other mats to form a floor level guarding
system for hazardous areas. The circuit through the mat must be
monitored by a safety-rated control unit, which may be a Minotaur
Safety Relay, MatGuard control unit, or MatGuard Mat Manager.
When the mat is clear, the control unit provides a signal to the
machine control circuit.
When a mat is stepped on, the conductive plates touch and the
resistance in the circuit falls to zero. This is monitored by the control
unit, which sends a shutdown signal to the machine.
Since the MatGuard safety mat is completely sealed (IP67), water,
liquids and coolants present no problem. In addition, the tough vinyl
will resist bleaches, acids, salts and many industrial chemicals.
The unique molding process allows the long life and reliability of the
mat.
