Zero Speed Switch Sensor Model ZS09P For Conveyors And More
The Phares Electronics ZS09P Zero Speed Switch Sensor protects your conveyor or other industrial machinery when it slows down, or stops unexpectedly. Monitor your conveyor belt for slippage. Stop conveyor “domino” effect fast before things get out of hand. Protect your equipment and minimize downtime. Keep your production lines flowing!
- Completely sealed. Suitable for outdoor use and in wash down areas
- Compact, self contained zero speed switch sensor with relay
- No additional control box needed
- Isolated relay contacts switch up to 5 amps, AC or DC, regardless of sensor input voltage
- Senses magnetic and low carbon steel targets (gear tooth, key stock, bolt head, etc.)
- 120 VAC or 6-24 VDC
- Over speed, under speed or zero speed detection
- LED indicators for instant visual confirmation (sealed)
- Precision trim pot for accurate relay set point adjustment (sealed)
- Detect speeds as slow as 0.03 RPM
- Detect speeds as high as 25,000 RPM
This little sensor is more than big enough to keep your conveyors out of trouble.

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.
