The Phares Electronics ZS09P Zero Speed Switch Sensor reacts quickly if your conveyor or other industrial machinery stops abruptly. Stop conveyor “domino” effect promptly before things get out of hand. The ZS09P Zero Speed Switch Sensor detects both magnetic and high iron content targets, such as a gear tooth, bolt head, key stock, etc.
- Compact, self contained zero speed switch sensor with relay
- No additional control box needed
- Isolated relay contacts switch up to 5 amps
- 120 VAC or 6-24 VDC
- Over speed, under speed or zero speed detection
- Contact arrangements: N.O./N.C. (form ‘C’), N.O. only, or N.C. only
- LED indicators for instant visual confirmation
- Precision trim pot for accurate relay set point adjustment
- Aluminum housing – other materials available
- Made in the U.S.A.
This little sensor is big enough to help protect your expensive machinery from major malfunctions and minor mishaps.
You will not be disappointed with its performance!

The Phares Electronics Zero Speed Switch Sensor Model ZS09P is a rugged, all-in-one device that combines sensor and relay, for use in over speed, under speed, or zero speed monitoring. Install on augers, bucket elevators, conveyors, exhaust fans, grinders, turbines, windmills and many other applications where shaft speed monitoring is needed. It has an adjustable set point for precise, accurate speed measurement, and reacts quickly if your machine stops abruptly.
The ZS09P Zero Speed Switch Sensor looks like a prox switch, but incorporates intelligent speed sensing circuitry not found in simple on/off devices. When machine shaft speed reaches the set point, the ZS09P Zero Speed Switch relay output changes state. It remains in this state until under speed or zero speed condition occurs.
Phares Electronics Zero Speed Switches have isolated relay contacts making it easy to incorporate into new or existing systems, or to replace obsolete zero speed switch sensors. Get your questions answered promptly at 727-444-0406.
