The Phares Electronics Zero Speed Switch Module Model ZS10 is particularly useful in applications where environmental conditions, such as high temperature, prohibit the use of certain electronics. In these cases, the sensor is installed in the prohibitive area and wired to the Phares ZS10 Zero Speed Switch Module which is located out of the prohibitive area. Use for applications in locations classified as hazardous only when properly coupled with UL approved intrinsically safe barriers and sensors.

For high temperature sensors, see Phares Electronics Digital Output Hall Effect Sensors and Geartooth Sensors.

 

Detail

The Phares Electronics Model ZS10 Zero Speed Switch System consists of the Phares ZS10 Zero Speed Switch Module, Sensor and Sensor Target, all sold separately.

Install the Sensor Target at the point of measure. Motion is detected when the rotating Target triggers the Sensor. When motion is either detected or reaches setpoint, the relay energizes and the relay output changes state. It remains in this state until either under speed or zero speed condition occurs, depending upon the application.

The Sensor Target can be a bolt head, geartooth, key stock, magnet, reflector, or other target depending upon type of Sensor used. The Phares ZS10 Zero Speed Switch Module supplies 12 VDC to an external Sensor. The Sensor must be 3 wire, sourcing (PNP) or sinking (NPN) signal. Sensor input signal is configured via two position selector switch located at the top right of the terminal strip.
The Phares ZS10 Zero Speed Switch Module uses frequency input from various types of sensors to determine the presence of motion or the lack thereof. Use the ZS10 for over speed, under speed, and zero speed applications.

Sensors and Targets

The Phares ZS10 Zero Speed Switch System requires a sensor and sensor target suitable for measuring speed. Sensor and sensor targets are sold separately.

Suitable targets are:

  • Magnetic Disk
  • Split Coupling
  • Geartooth wheel already on machine
  • Bolt head or key stock with high ferrous (iron) content already on machine.

 

Sensors

Phares Electronics Digital Output Hall Effect Sensors and Geartooth Sensors are simple on/off non-contact switching devices. Digital output signal is clean, fast and switched without bounce. They are magnetically activated switches which detect motion of the shaft speed monitoring target.
Phares Electronics’ Hall Effect Sensors and Geartooth Sensors are produced in a variety of sizes. Contact us for technical support and assistance with choosing a sensor and sensor target for your application.
