Optical Sensors are a type of sensor that uses light waves to detect and measure various conditions and properties, including ambient temperature, motion, level, position and distance. Photointerrupters are an example of optical sensor, which utilize light waves to measure the presence or absence of an object. Slot Type Photointerrupters, such as the PM-U24-R, have a slot-shaped sensing area and provide a rugged, reliable detection of objects and position. A typical PM-U24-R Photointerrupter features a Transistor Output, allowing for easier circuit integration. The following sections describe the application fields and working principles of the PM-U24-R Slot Type Photointerrupter.

Application Field

The PM-U24-R Slot Type Photointerrupter is widely used in industrial and medical equipment such as industrial robots, printing machines, AGVs (automated guided vehicles), and patient monitoring systems. These applications typically require a reliable detection solution and/or physical barrier to the object being detected. The PM-U24-R features an adjustable slot width, which allows for easy integration into various sensing requirements, ranging from wide to narrow sensing areas.

The PM-U24-R features a NPN-type output, which enables easy connection with most electrical control circuits. Furthermore, the PM-U24-R is designed for high-reliability, with a detection rate of over one million cycles and an attractive slim-line figure measuring 26.5mm (L) x 20mm (W) x 12.5mm (H).

Working Principle

The PM-U24-R Slot Type Photointerrupter works by sensing the presence/absence of an object entering its sensing area. The sensing area is bounded by two light-emitting elements, an infrared LED and a detector, which are aligned directly across from one another. The PM-U24-R slot has adjustable widths, allowing for sensing of objects anywhere from 0.25 mm to 8 mm in width.

When an object is present in the sensing area, the light emitted from the LED is interrupted. This interruption will switch the output of the PM-U24-R from “Light On” to “Light Off”, allowing the object to be detected. The output state change of the PM-U24-R will trigger an electrical signal, which can be read and interpreted by a variety of control systems.

The PM-U24-R is designed for a wide range of applications, including automation, safety, positioning, and detection. Additionally, the PM-U24-R features a slim-line design that allows it to be easily integrated into tight spaces.

Conclusion

The PM-U24-R Slot Type Photointerrupter is designed for a variety of industrial and medical applications. Its adjustable slot width makes it easy to integrate into various sensing requirements, while its NPN-type output makes it easy to connect to almost any electrical control circuit. Furthermore, the PM-U24-R features a rugged, reliable detection with over one million cycles, as well as a slim-line design that allows for easy integration into tight spaces.
