CE-VJ03-32MS2-0.5 AC Voltage Sensor 0-250V (50Hz)

ID: 3507_0

Ideal for mains voltage, this sensor measures up to 250V AC at 50Hz. Connects to an Analog Input or VINT Hub port.


This AC Voltage sensor measures line voltage on mains up to 250 Vrms. Powered by an external 12VDC power supply, the AC Voltage Sensor provides a 0 to 5VDC analog signal that is linearly proportional to the AC voltage measured at the terminal blocks.

The AC Voltage Sensor can easily be mounted using the screw holes, or on a 35mm wide DIN rail for quick installation. The terminal blocks accommodate conductors of up to AWG #16.

The voltage sensor connects to an analog input on Phidgets I/O boards. The formula to translate the output voltage into measured voltage is:

Vrms = Vout * 50


You can use a 12V sensor adapter to connect this sensor to your InterfaceKit or Hub. See the Connection & Compatibility tab for more details.

Mounting Suggestion

Warning: The AC Voltage Sensor needs to be attached in parallel with the line voltage. This requires cutting and using loose ends of high power cables. ALWAYS be sure to turn off the power running through the cables while manipulating and before cutting the cables. When attaching the cables, be sure to follow your country’s wiring code to ensure safe installment of the sensors and to reduce the risk of injury and fire. If you are uncomfortable, consult with a certified electrician.


12V Sensor Adapter


This voltage sensor requires a 12V power supply and outputs a 0-5V signal depending on the voltage measurement. For a simple way to provide 12 volts, you can use our 12V sensor adapter. It uses the 5V supply from your InterfaceKit or Hub and steps it up to 12V while simultaneously passing the 0-5V signal from the sensor into the Phidget cable.

To connect the sensor, connect the terminals as follows:

Function 3507 - Voltage Sensor 1144 - 12V Sensor Adapter
+12V 5 +12V
Ground 6 GND
