The Model 452 Motion Switch allows a PLC or other circuit to do target timing analysis by
providing a signal that varies according to the monitored speed.
It uses digital signal processing to convert the sensor timing signal to a current loop signal.


Output:2-wire, 4-20mA Current Loop
Dimensions:5-1/4" (13.5 cm) Long x 1-1/4" (3.2cm) diameter
Weight:1 lb (454 grams)

Applications include monitoring of all conveyor types, rotary type devices such as fans, and any
equipment with continuous motion. Sensor detects targets per minute.

Operational benefits include cost savings and reduced downtime by preventing material spills or extensive equipment damage.
The 452 acts as a safe guard as long as the PLC/ control circuit is integrated to control other conveyors or equipment.

When two or more 452s are used then sequencing and total system automation is accomplished.
