Optical Sensors are defined as a type of sensor that use a light source to measure physical metrics. This can be for a wide breadth of applications, from determining the level of liquid in a container, to measuring distances along a line. In any case, the Optical Sensor must detect some form of a change in a source of light or a beam. This change produces an electrical signal that can then be used to measure or convert to a specific metric.

Photointerrupters are a type of Optically Sensors that measure the interruption of a beam of light. The most common type of photointerrupter utilizes a slot, in which the beam of light passes through. When the object interrupts the beam of light, such as when a chapter or do is open or closed, the light intensity can be detected and used as an on/off state. Most photointerrupters are used in applications such as switches, level sensors, limit switches, counter devices, counting/timing devices and other similar kinetic applications.

The PM-R24-C3 photointerrupter is a slot type with transistor output. It is an optically coupled device that consists of an infrared emitting diode and a silicon phototransistor which is encased in a black plastic package. The package is shielded to improve the immunity to disturb generated from the external environment. The device is specially designed in such a way that the light emitted from the infrared diode is totally blocked from the phototransistor when the slot is blocked.

The working principle of the PM-R24-C3 is quite simple. A beam of infrared light is emitted from the diode and is sensed by the phototransistor. When the slot is blocked by an object, the beam of light is blocked and the phototransistor will no longer detect the infrared light. This generates the on/off-signal, which is then passed through the transistor as an output.

The PM-R24-C3 Transistor output Photointerrupter can be employed in all kinds of applications in industrial, home or office automation, consumer electronics and many other applications. It can be used as a limit switch in a variety of manufacturing equipment or as part of a fuel management system. Due to its great sensitivity and quick response time, the PM-R24-C3 can be used in motion sensing systems or as part of an automation process.

The PM-R24-C3 is also ideal for office automation applications. It can be used to detect the presence or absence of people in a specific area or to detect movement. It can also be used in conjunction with an infrared remote control to detect the presence of an IR signal and allow it to be used for controlling other devices. The PM-R24-C3 is also great for security applications, such as for detecting the opening of doors or windows, or the motion of an intruder.

In conclusion, the PM-R24-C3 Transistor output Photointerrupter is one of the most versatile optical sensors used in all sorts of applications. Its excellent sensitivity, compact size, immunity to disturb and quick response time make it a great choice for a variety of sensing tasks in a number of different environments.
