Optical Sensors - Reflective - Logic Output provide a cost-effective solution for detecting objects in industrial applications. GP2A231LRSAF is one type of this class of sensors. It combines a state-of-the-art light source and photo IC receiver with a wide choice of reflective models, making it ideal for many types of applications. This paper will discuss the application fields and working principles of GP2A231LRSAF.

Application Field

The GP2A231LRSAF is mainly used in industrial applications such as detecting the presence of objects, detect and count parts, and detect and measure distances. It can also be used for bar code reading, line following, color detection, presence detection, and automation control applications, as well as in robotics or industrial inspection systems.

The GP2A231LRSAF uses a bright LED light source transmitted to the photo-interrupter and optimized to ensure flexibility in reflective sensing. Its compact size allows it to fit into tight spaces, and the sensor can withstand harsh environments. It has high repeatability and immunity to background light interference.

The sensor has a short response time, low power consumption and low noise. The output can be adjusted with a set of potentiometers to account for changes in the ambient light. It is also very sensitive to changes in light intensity, allowing for more accuracy in detecting objects and distances.

Working Principle

GP2A231LRSAF is a logic output optical sensor. It consists of two parts: a light source and a receiver. The light source emits either an infrared or visible light beam towards a reflective surface, and the receiver receives light reflected from that surface. If an object interrupts this beam, it will fail to reach the receiver. If the received beam is strong enough, it will be detected by the receiver and the output signal will change.

When integrating the light source and the receiver on a single package, the GP2A231LRSAF is able to detect objects even in difficult environment conditions. The LED can be operated from a 4 to 24V power supply, and can select different degrees of sensitivity and response time using adjustment potentiometers.

The GP2A231LRSAF can detect a 20mm white reflector from a distance of 5 to 20mm. While the GP2A231LRSAF is designed for detecting small objects, it is sensitive enough to detect larger objects as well. By changing the LED’s output power and adjusting the potentiometers, it is possible to extend the detection range up to 30mm.

The GP2A231LRSAF is a compact optical sensor that can be used in a wide range of applications. It is easy to set up and configure, and can handle a wide range of environmental conditions. With its flexibility and reliability, it is the perfect solution for a variety of reflective sensing applications.
