The Phares Model ZS12 Zero Speed Switch Sensor is a rugged, all-in-one device which includes replaceable sensor and relay, for use in over speed, under speed, or zero speed monitoring. It protects your conveyor or other industrial machinery when it slows down, or stops unexpectedly. The ZS12 Zero Speed Switch has an adjustable set point via multi-turn trim pot for precise, accurate speed measurement, and is able to react within a fraction of a second if your conveyor or machine stops abruptly.

When machine shaft speed reaches the set point, the ZS12 Zero Speed Switch relay output changes state. It remains in this state until under speed or zero speed condition occurs. The Phares ZS12 Zero Speed Switch has 3 diagnostic LED’s. These LED’s indicate Power, Pulses from Sensor input signal and Relay status. LED’s are labeled Power, Pulse, and Relay. A multi-turn trim pot is used for adjusting the set point.

The ZS12 Zero Speed Switch has isolated relay contacts making it easy to incorporate into new or existing systems, or to replace obsolete zero speed switches.

Install on augers, bucket elevators, conveyors, exhaust fans, grinders, turbines and many other applications where shaft speed monitoring is needed.
