The PM-L25-R is an optical sensing device of the slot type, that is, an infrared light emitting diode is placed opposite an infrared receiver. This type of device is referred to as a "photointerrupter". The PM-L25-R belongs to the category of "logic output" sensor, producing an output of either high or low, depending on whether an object is present or not.

The PM-L25-R is designed for sensing applications such as position sensing, paper density sensing, and limit switch functions. The PM-L25-R has a sensing range of 3mm and an operating temperature range of -25°C to 80°C. The device is very compact, measuring only 11.86mm x 4.19mm x 3.2mm. The package is appropriate for surface mount technology.

The working principle of the PM-L25-R is very simple. When the application calls for sensing an object, the IR LED and receiver are placed at a set distance from one another, and an opaque object is placed in between them, thus blocking the light and producing a low output at the PD pin of the device. When the sensed object is removed, the device will produce a high output at the PD pin. This can be done with either a stationary or moving object, depending on the specific application.

In addition to the ease of use and installation, the PM-L25-R has many other advantageous features. It has lower power consumption due to the use of an infrared LED, and also a high switching speed of up to 200kHz. With its small size and wide operating temperature range, the PM-L25-R is suitable for use in harsh environments.

In applications where a logic output is needed, the PM-L25-R is the perfect choice. Its compact size and wide operating temperature range make it suitable for a variety of environments and applications. It also has a sensing range of 3mm and a high switching speed of up to 200kHz. All of these features make it an ideal choice for those looking for an optical sensing device that is easy to install and use.
