PM-U24P

The PM-U24P photointerrupter is a slot-type optical sensor with a transistor output. It is ideal for use in linear or motor speed sensing applications where the object to be sensed passes through a slot or gap in the device housing. The PM-U24P is available in two forms, an integral mounting form and a panel-mount version. It is suitable for applications in consumer electronics, office automation, medical equipment, motor control systems, and other areas where a reliable, high-accuracy, contactless control device is required.

The PM-U24P photointerrupter is based on the optical principle of emission and reception of light pulses. When a light emitting diode (LED) within the device emits a beam of light which passes through a slot or gap in the device, a phototransistor located within the device then receives the light signal, amplifies it, and converts it into an electrical signal. The electrical signal is then used to activate a switching circuit within the device, which in turn provides an output signal that can be used to operate a variety of different devices or circuits.

The PM-U24P features a built-in feedback circuit which filters out external noise and vibration. This feedback circuit also ensures an exceptionally accurate performance with high signal-to-noise ratio and the device can withstand a wide range of operating conditions. The PM-U24P features an integrated preamplifier which provides a stable output signal even when used in environments with unstable light sources. The PM-U24P also features a temperature compensation circuit which helps maintain the accuracy of the output signal over a wide temperature range.

The PM-U24P has a wide variety of uses and applications. It can be easily integrated into systems for counting, speed sensing, length sensing, object recognition, and proximity sensing. The PM-U24P is also ideal for positioning, automation, flow control, and obstacle detection applications. Its high sensitivity and reliable accuracy make it an ideal choice for applications requiring accurate speed sensing and object detection, such as in robotic or automation systems. The PM-U24P can also be used in safety systems to detect the presence of an object within a certain range or to provide an alarm if something passes through its sensing area.

In conclusion, the PM-U24P is an ideal and reliable solution for speed sensing, object detection, and positioning applications. Its high sensitivity and accurate performance makes it highly suitable for use in systems that require reliable operation and detection accuracy. Its feedback circuit provides a stable output signal even in unstable and noisy environments while its preamplifier allows a wide variety of devices or circuits to be driven. Its temperature compensation circuit ensures accurate performance over a wide temperature range.
