The Panasonic CX-411 (CX-411D+CX-411E) Beam Type Photoelectric Switch and Sensor is a compact and versatile sensor that can be used for a variety of applications. It is a thru-beam type sensor, which means it uses two separate units, the emitter, and the detector, to detect the presence or absence of an object. The emitter emits a beam of light, and the detector detects the presence or absence of this beam. If the beam is broken, the sensor outputs a signal.
