Our Bulletin 42CA 18 mm Plastic Cylindrical General Purpose Sensors are ideal for light- to medium-duty industrial applications. These sensors flash an indicator if the signal level is too close to the detection threshold. This helps you align the sensor and warns against detection of a background or degradation of the application characteristics.
