Optical Sensors are widely used in various industries due to their high sensitivity, fast response time, and long-term reliability. Photointerrupters, which detect the passage of an object between a light source and an optical receiver such as a normal transistor or phototransistor, are a type of optical sensor. In this article, we will discuss the application field and working principle of the OPB980P51 slot type photointerrupter with logic output.

The OPB980P51 is a device designed for applications with medium- to high-speed positioning and counting requirements. It is typically used in assembly line operations, photoelectric sensing, medical device control, machine control, and laboratory industries. The OPB980P51 features an integral box construction with a preassembled optical receiver, photo light source, and a dust-proof and waterproof housing. It is also designed with a narrow slot to ensure reliable operation with small objects. The device has a response time of 0.5ms, and its compact size allows for easy installation in tight spaces.

The working principle of the OPB980P51 is based on the interrupting of the light source when an object passes through the slot. The photo interrupter contains an optical sensor and a phototransistor. When the object moves through the slit, part of the light from the light source is blocked and is detected by the photo sensor. This interrupts the current flow from the phototransistor, and the corresponding output from the device is in the form of a logical signal.

The OPB980P51 is designed to be highly reliable and provides a high degree of accuracy when used for sensing and positioning operations. It also offers a wide operating voltage range and a wide operating temperature range, making it suitable for use in extreme conditions. The device is also designed to be highly resistant to humidity, dust, and other environmental conditions, and its compact size allows for easy installation in limited spaces.

The OPB980P51 slot type photointerrupter with logic output is a versatile device that is suitable for use in a wide range of applications. Its high sensitivity and fast response time make it ideal for use in assembly line and laboratory operations, and its durable construction and wide operating temperatures mean it can also be used in extreme conditions. With its reliable performance and wide range of applications, the OPB980P51 is an ideal choice for sensing and positioning operations.
