Safety sensor FSRST

The Tempatron FSRST shaft rotation sensor is designed to prevent access to a rotating machine until it has slowed to a safe speed. If the sensor does not receive a pulse within the adjustable time setting, the output relay will energise which can then disable a machine guard to enable safe access by the machine operator. The shaft rotation sensor is housed in a compact DIN48 square enclosure which can either panel mount or surface/DIN rail mount to a socket and is auxiliary powered from either 110Vac or 230Vac. The 5 Amp rated single pole changeover relay output contact is isolated from the supply voltage, and use of the normally open contacts enables failsafe operation in the event of power failure. The FSRST has two LEDs to indicate both power and relay status.
