Optical Sensors - Photointerrupters - Slot Type - Transistor Output

Introduction

Optical sensors are devices that detect light or infrared rays. They are used in a wide range of applications, from safety systems to automated production processes. One type of optical sensor is a photointerrupter, which is designed to detect when an object interrupts a beam of light or infrared radiation. Photointerrupters come in several different types, including slot type and transistor output. The WF225-B4150 is a slot type, transistor output photointerrupter. This article explores the application field and working principle of the WF225-B4150.

Application Field

The WF225-B4150 is a slot type, transistor output photointerrupter. It is designed to detect when an object interrupts a beam of light or infrared radiation. This type of photointerrupter is commonly used for sensing the position or movement of objects, such as paper or cardboard, in a variety of industrial applications. Its small size and low cost make it particularly suited for applications where a low-cost sensing solution is needed.The WF225-B4150 has a slot type optical sensor, meaning it is made up of two parts: an emitter and detector. When an object passes between the two components, it interrupts the beam of light or infrared radiation, and the detector sends a signal to an external circuit. The detector can detect the presence or absence of an object within a few milliseconds.The WF225-B4150 is designed to be simple to install and operate, and it is compatible with most PLCs and controllers. It also offers a reliable sensing solution, with a long working life and high immunity to interference from other electrical devices.

Working Principle

The WF225-B4150 is a slot type, transistor output photointerrupter. The device works in a simple and effective way: when an object interrupts the beam of light or infrared radiation between the two parts, it sends a signal to an external circuit.The WF225-B4150 consists of two parts: an emitter and a detector. The emitter is a small LED light source, and the detector is a phototransistor. When an object passes between the two components, it interrupts the beam of light or infrared radiation, and the detector sends a signal to an external circuit.The LED light source generates an infrared beam between the two parts of the WF225-B4150, and the phototransistor is able to detect when the beam is interrupted. When the beam is interrupted, the phototransistor sends a signal to an external circuit, which can then activate a relay or other device. The external circuit can be configured to respond to different signals, depending on the application.

Conclusion

The WF225-B4150 is a slot type, transistor output photointerrupter. It is designed to detect when an object interrupts a beam of light or infrared radiation. This type of photointerrupter is commonly used for sensing the position or movement of objects, such as paper or cardboard, in a variety of industrial applications. Its small size and low cost make it particularly suited for applications where a low-cost sensing solution is needed. The device works by detecting when an object interrupts the beam of light or infrared radiation between the two parts, and sending a signal to an external circuit. This provides a reliable and low-cost sensing solution for a wide range of applications.
