Pressure-sensitive safety mat detects light loads
FF-SM Series safety mat is a pressure-sensitive protective device that uses an infrared modulated light source spread by a fiber optic cable and operates in a positive break light mode. The presence of a load greater than 66.1 lb on any point of the sensing surface bends the fiber optic cable. The loss in signal de-energizes positive guided output relays and initiates an emergency stop signal. Control reliability is designed in by using redundancy and cross-checking.
