Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The H21B6 Optical Sensor is a photointerrupter with a slot type and transistor output. It is used in a variety of applications such as textile machines, printing presses, inspection machines, and automatic door openers. This type of sensor is easily integrated into existing machinery and can be used in both indoor and outdoor applications.

Working Principle

The H21B6 Optical Sensor uses photoelectric technology to detect the presence of an object or obstacle within a specific range. The sensor works by emitting a light beam from its internal LED. This beam is then reflected off the object or obstacle and onto a photo-voltaic element in the optical receiver. The receiver is then able to detect the presence of the obstacle, at which point an electrical current is sent through a DC relay to activate the required mechanical response.

When the photointerrupter is used in conjunction with an additional light-emitting diode (LED), it can be used to detect and measure the precise location of an object or obstacle. This application is useful for applications such as light curtains and motion-detection systems.
