Optical Sensors, specifically Photointerrupters, use a light sensitive device to detect the presence or absence of light. Photointerrupters can be divided into two categories: Slot Type and Transistor Output. Within the Slot Type category is the RPI-0125. The RPI-0125 has a variety of application fields and its working principle is quite simple.

Application Field

The RPI-0125 is a Slot Type Photointerrupter and is ideal for use in motor speed control, object detection, gap measurement, linear scale readout, angular displacement detection and paper feeder applications.

The RPI-0125 can be used in motor speed control to measure the rotation of a motor\'s shaft. Object detection can be used to detect the presence objects in an application whether they are solid, liquid or gas. Gap measurement can be used to measure the gap between two objects in an application without physical contact. Linear scale readout is used to measure linear distances in an application. Angular displacement detection is used to detect the angular displacement of an object in an application. The RPI-0125 can also be used for paper feeder applications and is suitable for feed pin connected paper feeders.

Working Principle

The working principle of the RPI-0125 is quite simple. It contains a light source and a photosensitive detector, which are both enclosed in a cylinder. When an object is placed in front of the cylinder, it blocks the light from the light source and the photosensitive detector does not detect the light. When the object is removed, the light is no longer blocked and the photosensitive detector detects the light. This allows the RPI-0125 to detect the presence or absence of the object.

The RPI-0125 also has an integrated amplifier, which allows it to detect the presence or absence of the object from a greater distance than other Photointerrupters. The RPI-0125 also has LED indicators on the side of the cylinder, which make it easy to detect the presence or absence of light from greater distances.

Conclusion

The RPI-0125 is a valuable Slot Type Photointerrupter for a variety of applications. Its simplicity is one of its strengths, as its working principle is quite straightforward. In addition, its LED indicators make it easy to detect the presence or absence of objects from great distances. With its numerous applications, the RPI-0125 is a powerful and versatile optical sensor.
