WebMar 8, 2024 · To test the polarity of an NPN sensor, remove the load wire from the input module. With the voltmeter measuring the open load wire observe the voltage as the sensor energizes. An NPN sensor will swing between ‘open’ and ground, which would likely show 0 volts nearly the entire time, regardless of the energization state. WebJun 13, 2010 · A photoelectric sensor is a device that detects a change in light intensity. Typically, this means either non-detection or detection of the sensor’s emitted light source. The type of light and method by which the target is detected varies depending on the sensor. Photoelectric sensors are made up of a light source (LED), a receiver ...
