SN04-N Inductive Proximity Sensor - 5mm

ID: 3528_0
Recommended for new designs: Phidgets Inc. is not the original manufacturer for this product, but we intend to sell it (or a similar replacement with a compatible form, fit and function) for as long as it is available from the supplier.

This inductive sensor can detect metallic objects within 5mm and behaves like a switch that connects to a digital input.

This inductive proximity sensor will detect the prescence of a metallic object within 5mm of the surface of the sensor. The detection distance may vary slightly depending on the shape, size, and type of metal the object is made of. It can detect through thin, non-metallic materials and has an LED indicator that turns on when the device is powered, and increases in brightness when an object is detected.


The 3528 comes with ferrules crimped onto the wires to ensure a good connection when used with screw terminals. You can use a 12V sensor adapter to connect this sensor to your InterfaceKit or Hub. See the Connection & Compatibility> tab for more details.

12V Sensor Adapter

This sensor requires a 12V power supply and outputs a 0-5V signal depending on wheter the sensor is triggered. 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 wires as follows:

Function 35231144
+12V Brown +12V
Ground Blue GND
Data Black ANLG
