Optical Sensors - Photointerrupters - Slot Type - Logic Output

The OPB912L55 is an infrared logic output slot type photointerrupter. This type of photointerrupter is used whenever a highly sensitive, narrow beam optical device is needed. Photointerrupters are typically used to detect the presence of an object or material in a given space or to measure the exact position of an object or material. These devices are characterized by their high immunity to external light, their small size, and their fast response times.

Application Field

The OPB912L55 is most commonly used in consumer electronics and industrial automation applications, due to its ability to accurately measure relative positions and detect the presence of materials or objects within a certain area. It can also be used to monitor movement and detect changes in motion. This device is highly sensitive to position, and can detect small changes in a winding or rotating shaft. Other potential uses for this device include detecting the position of shipping containers, industrial printing presses, slitter drums, conveyor belts, conveyor rollers, and even money-counting machines.

Working Principle

The OPB912L55 works by using infrared light to detect the presence of an object or material within its sensing area. It uses two emitters and a detector to generate a light beam directed towards the object or material being sensed. The light beam is then scattered against the object or material being detected and the scattered light is detected by the receiver. The two emitters and the detector are connected to an integrated circuit, which processes the light signal and converts it into an electrical signal. This electrical signal is then sent to an output circuit, where it can be used to control the operation of a machine, activate a robotic arm, or even activate an alarm.

The OPB912L55 is an excellent choice for applications that require precise positioning, due to its ability to sense small variations in the position of an object or material. This device is highly reliable and resistant to external light interference, making it suitable for a wide variety of applications.

Overall, the OPB912L55 is a reliable and versatile photointerrupter which can provide accurate measurement and detection abilities to a variety of industries and applications.
