3527_0 - Autonics PR30-15DN Inductive Proximity Sensor - 15mm


Product Features

This inductive sensor can detect metallic objects within 15mm and behaves like a switch that connects to a digital input.

Product Description


Proximity sensors are the most common and affordable solution for no-touch object detection. The most commonly-used proximity sensor is the inductive type, which generates an electromagnetic field to sense metal objects passing close to its face. This is usually the easiest sensing technology to apply in applications where the metal object to be detected is within an inch or two of the sensor face.

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 metal being detected and will in general be between 70 to 80% of the standard distance.

  • Mounting Hardware Kit




This sensor connects to any device with a Digital Input.

This is how you connect the 3527 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 3527 Brown wire.
  • Connect the 3527 Black wire to a Digital Input on the 1018.
  • Connect the Power supply Ground Wire and the 3527 Blue wire to the Digital Input Ground connector on the 1018.

Note:When the 3527 is connected to a 1012, it will behave as a Normally Closed (NC) sensor instead of Normally Open (NO).

The 3527 can also be used with the 1144 - 12V Sensor Adapter if you want to connect to a device with an analog input without worrying about providing a 12V power supply.

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.
