This capacitive sensor can detect metals and some other materials within 8mm and behaves like a switch that connects to a digital input.
This capacitive proximity sensor is used for non-contact detection of metallic and non-metallic objects such as liquid, powder and granular materials; it can also detect materials through glass or plastic walls.
Note that the standard detecting distance is based on a standard shape approaching the sensor in a standard way. The real detecting distance will vary depending on the shape, thickness and type of material being detected.
You can adjust the operating distance by turning a screw placed on the side of the sensor.

This sensor connects to any device with a Digital Input.
This is how you connect the 3523 to a Phidget board that does not have 12V power such as the 1018, 1012, 1202, and 1203 using our 12VDC Power Supply:
- Connect the +12 wire from the Power Supply (that's the one with the white line) to the 3523 Brown wire.
- Connect the 3523 Black wire to a Digital Input on the 1018.
- Connect the Power supply Ground Wire and the 3523 Blue wire to the Digital Input Ground connector on the 1018.
Note: When the 3523 is connected to a 1012, it will behave as a Normally Close (NC) sensor instead of Normally Open (NO).
For boards that have power input, if the supplied power is within 12-24VDC, the +V line can be connected to the terminal block, powering the sensor from the Phidget. The 1019, 1073, all accept external power.
