Control unit, Sensor mats – Rockwell Automation 440F MatGuard, 440F-C4000 Mat Controllers User Manual

The vinyl outer surface of the mat is completely sealed to resist the ingress of liquids. It will resist
bleaches, acids, salts and most industrial chemicals. Refer to section 5.3.1 for detailed guidance on
chemical resistance.
The system operates at 24V DC with restricted fault current. Damage to the mats or interconnecting
wiring will not therefore generate any electrical shock hazard in normal circumstances.
