Optical sensors are sophisticated devices that detect the presence of light or measure its intensity. Among the different types of optical sensors, photointerrupters or slot-type photointerrupters are used to detect the presence or absence of objects passing through the measuring slot. The WF30-95B416 is a widely used photointerrupter that can be used for a variety of applications and is particularly suitable for use in high-speed detection, such as the detection of a minute gap or the passage of a moving part. This article will discuss the applications and working principles of the WF30-95B416.

Applications of WF30-95B416

The WF30-95B416 is a 3-pin, slot-type photointerrupter with a transistor output. Its features make it ideal for fast-moving objects and miniaturized systems. It is used in applications requiring detection in tight areas, high-speed signal detection, and optical rotation detection. This photointerrupter can also be used for inspecting the width of moving objects, detection of label, detection of transmittance, and for presence and absence recognition.

The WF30-95B416 is widely used for automation equipment and factory automation systems. It can be used for machine vision systems, industrial robotics, intelligent vending machines, programmable logic controllers (PLCs), medical equipment, pacemakers, injection molding machines, and various other factory automation applications. It is also used in applications which require high accuracy when detecting objects.

Working Principle

The WF30-95B416 consists of an infrared LED and a phototransistor. When no object is passing through the measuring slot, the light emitted from the LED is detected by the phototransistor, and the transistor remains in the off-state. When an object passes through the slot, the LED emits light which is blocked by the object, and the phototransistor will turn on. This change in state triggers the output signal to go low, alerting the system of the object\'s presence.

The response speed of this photointerrupter is typically measured as the ON-time delay, indicating the time taken from the moment the object enters the measuring slot to the time the output signal is triggered. It is generally fast, with an ON-time delay of 4.5 ms or less during normal operation, and can detect even fast-moving objects with speeds up to 10 m/s. The WF30-95B416 also features a high insulation voltage of up to 300 V DC.

The WF30-95B416 is a reliable and efficient photointerrupter which makes it ideal for a variety of applications. With its high-speed response and high-voltage insulation, it is a popular choice for applications where detection accuracy and speed are paramount. Additionally, its compact size and 3-pin design make it suitable for applications where space is limited.
