What is the Through Beam Photoelectric Sensor?
The through beam photoelectric sensor have the transmitter and receiver, its working principle is: the light emitted by the transmitter directly into the receiver, when the object is detected after the transmitter and receiver blocked between the light, the photoelectric switch will produce a switch signal.
Unlike a reflective photoelectric sensor, the former is done through an electric-light-electric conversion, while the latter is done through a medium. The characteristics of the photoelectric switch are: can identify opaque reflective objects, large effective distance, not easily disturbed, high sensitivity, high resolution, high brightness, low power consumption, fast response time, long service life, lead-free, widely used in: coin-operated machines, small appliances, coin-operated machines, automatic sensors, fax machines, scanners and other equipment.
