It also finds applications in robotics, motion control, and other industrial applications that require precise positioning and level detection.The WFM180-120P321 can be used for edge detection of objects and for monitoring and controlling linear or rotational movement. It can be used to detect the presence of an object by interrupting the light beam between the emitter and receiver of the device.The WFM180-120P321 can also be used in safety related applications. It can detect if a machine or object is in the correct position, and can be used to shut off power to hazardous machinery or equipment if an unsafe condition is detected.

Working Principle

The WFM180-120P321 is a photointerrupter with slot type and transistor output. It is a three terminal component with an LED light emitter and a photodetector housed in a plastic package. The component produces a digital output signal when a light beam is interrupted.When an object interrupts the beam between the LED emitter and photodetector, the component emits a digital output signal. The output signal can be used to drive circuits or activate peripherals. The output signal is active low, meaning that it goes low when the beam is interrupted.The WFM180-120P321 has an operating distance of 120mm and a response time of 0.3ms. The component has a wide operating temperature range of -20 to 70°C, and can operate at a supply voltage of 5 to 24V.

Conclusion

The WFM180-120P321 is a photointerrupter with slot type and transistor output. The component is designed for precise level detection and positioning sensing applications, and is especially suitable for safety related applications. It operates by emitting a digital output signal when a light beam is interrupted between the LED emitter and photodetector. The component has an operating distance of 120mm and a response time of 0.3ms, and can operate over a wide temperature range and supply voltage.
