Optical Sensors - Photointerrupters - Slot Type - Transistor Output

The WFM80-60N321 is a photointerrupter from the family of slot type transistor output components. It features a 4.2mm gap size, an operating wavelength of 800 to 1100 nm, and a collector current of 200mA. This photointerrupter is made up of an emitter-receiver pair, consisting of an infrared LED emitter and a photodiode receiver. The device is ideal for applications that monitor the interruption or presence of objects on a line or production conveyor.

Application Field

The WFM80-60N321 photointerrupter is highly suitable for many industrial applications such as the detection of the arrivals and departures of containers on a production line, the counting of small items on a conveyor wheel, and the detection of the passage of printed materials. It can also be used in the process control industry, where it can detect irregularities in the production process, such as an incorrect sequence of materials or objects on a conveyor belt.

Working Principle

The photointerrupter has an emitter-receiver pair at the ends of a 4.2mm gap. An infrared LED emits a continuous light beam that the photodiode receiver detects. The device works by sensing the interruption of the light beam. This interruption is caused when an object passes through the gap and blocks the light. The receiver then sends an output signal to a controller indicating the presence or absence of the object.

The WFM80-60N321 is typically equipped with an LED emitter and a Photodiode receiver. The emitter is powered by a DC voltage source and produces a continuous light beam. The Photodiode receiver is connected to the controller through a transistor switch, which toggles between the two states when the interruption occurs. The controller is then able to detect or count the number of interruptions to determine the presence or position of objects on the production or conveyor line.

The WFM80-60N321 has a switching frequency of up to 800 Hz and a collector current of up to 200mA. It has a narrow sensitivity wavelength in the infrared spectrum and is resistant to ambient light and vibration. The device is also highly reliable and robust, making it ideal for many industrial applications.

Conclusion

The WFM80-60N321 Photointerrupter is a slot type transistor output device that is suitable for many industrial applications, such as counting small items on conveyor wheels, detecting irregularities in production processes, and monitoring the arrivals and departures of objects on a production line. It has an operating wavelength of 800 to 1100 nm, a switching frequency of up to 800 Hz, an LED emitter, a collector current of up to 200mA, and a photodiode receiver. This makes the device highly reliable and robust, making it ideal for use in many industrial applications.
