Optical Sensors – Photointerrupters – Slot Type – Transistor Output – WF80-95B416 application field and working principle

Introduction

The WF80-95B416, a slot type, transistor output photointerrupter, is a popular optoelectronic device used for sensing in a range of applications. This article explores the application field of the device and its working principles.

WF80-95B416 Application field

The WF80-95B416 optoelectronic sensor is used mainly in commercial, industrial and automotive applications for a variety of purposes.It is used in flatbed scanner assemblies for measuring the speed of package movement. The device is also used to measure the speed of a conveyor belt. The output signal generated by the WF80-95B416 is used to detect the presence of documents on an indexing belt or to measure the motion of a rotary encoder.Moreover, it is used in automated assembly and packaging machinery. WF80-95B416 is also used as a limit switch, detecting the extreme positions of a moving part. It is commonly used in automotive applications for determining the speed of a shaft rotation or the presence of an object in a path. Additionally, it is used in robotic systems for providing feedback to the system.

Working Principles of the WF80-95B416

The WF80-95B416 is a slot type optoelectronic sensor that consists of two main components: an infrared LED and a phototransistor. It is built in a tiny, black plastic housing which ensures the construction is water and dust proof.When an object passes through the slot, the light from the infrared LED is interrupted momentarily, causing the phototransistor to emit an output current. This output current can be used as a control signal to trigger an action such as stopping a motor or turning on a light.The WF80-95B416 optoelectronic sensor has a wide range of sensing distances ranging from 0.5mm to 1.3mm. It has an adjustable sensing threshold, allowing the user to adjust the sensitivity of the sensor. Furthermore, the device has the capability to recognize the presence and absence of an object in complete darkness.

Conclusion

The WF80-95B416 slot type photointerrupter is a useful optoelectronic device that is used in a variety of applications. It is capable of sensing the presence of an object accurately and has a versatile range of sensing distances. The device is easy to use and is cost effective, making it a popular choice for many applications.
