OPB891P55 is an optical sensor product typically classified as Optical Sensors - Photointerrupters - Slot Type - Transistor Output. Specifically, it is a miniature, individual slot-type photointerrupter with a combination of an IR light source (an emitting diode) and an NPN-output silicon phototransistor, and a black-teeth structured for the elements. It is suitable for high-density mounting.

The basic application field of OPB891P55 is in detecting the rotation and revolution of a target. It is mainly used in motors, gear position monitoring systems, mechanical sensors, and other applications where rapid, precise positioning is required. In addition, it is used in the presence/absence detection of a small target, and simple-shaped targets can also be recognized. The OPB891P55 can also be used in camera autofocusing systems and exposure control.

The working principle of OPB891P55 is quite simple. Basically, light energy emitted from the emitting diode is used to detect the changes in an adjacent target. The light is absorbed by the target, and then a light beam is reflected back to the phototransistor while the target exists in the light\'s path. Therefore, by using this interrupter, the changes in the environment can be detected accurately and rapidly.

Furthermore, the OPB891P55 provides substantial design versatility. It has a low-profile mechanical design that is optimized for tight spaces, while also providing easy installation and a range of electrical performance parameters that can be configured for different applications. In addition, its mechanical construction is designed to ensure that when the interrupter is in use, the reflected light does not interfere with the operation of the device.

OPB891P55 is an economical and high-performing optical sensor suitable for a variety of applications. Its high-speed, accurate sensing performance, versatility, and compact size make it an attractive choice for detecting rotation, revolution, and changes in a target. With its combination of features and performance advantages, it is expected to find a wide range of practical applications.
