Phares Sensors & Automation
A slowing or stopped machine can quickly become a costly production problem. Phares Sensors & Automation provides zero speed switches, industrial tachometers, and sensors that detect changes in equipment speed—helping you respond before a small problem becomes an unexpected shutdown.  Phares Electric is now doing business as Phares Sensors & Automation.

ZS09P Zero Speed Switch Sensor

The ZS09P is a compact, self-contained zero speed switch for applications requiring a higher-power relay output. It switches loads up to 5 amps, making it a good choice for directly controlling equipment or control circuits without a separate control module.

Why Choose Phares Electric….

Rugged Durability:  The sensors are engineered for harsh industrial environments, including those with heavy vibration, high temperatures, moisture (wash-down areas), dust, oil, and corrosive elements.

Ease of Integration: Phares offers “all-in-one” solutions (such as their ZS09P and ZS12 models) that combine the sensor and relay into a single, self-contained unit. This eliminates the need for extra control boxes or complex PLC setups for simple monitoring tasks.

Reliability and Support: Customers frequently cite high product reliability—often describing it as “unprecedented”—and praise responsive customer service and clear technical documentation.

Our years of experience enables us to apply technology in new ways.  As a result, we offer innovative, field-proven products to detect zero speed, underspeed, overspeed, and rotational speed that protect equipment and materials.
