PM-L25-C3 is an optical sensor that is a part of the photointerrupters category and the slot type logic output. This type of optical sensor is designed to provide two-way signals between an emitter and receiver in a variety of applications. Its purpose is to sense a specific gap within a specific area and to identify the presence of something within the gap.

The PM-L25-C3 consists of a pair of infrared emitting and receiving elements and an integrated circuit within a single package. This optical sensor is made with an optical transmission groove that can accurately detect presence, position, or size of objects within the gap. Additionally, the emitter is equipped with a function that enables the receiver to maintain stability against ambient light. The optical sensor is designed with a wide range of operating-voltage and intrinsic safety capability.

Applications of the PM-L25-C3 occupy level control switches, paper thickness gauging, proximity switches, height-measuring gauging, speed measuring, revolving-piece detection, presence/absence detection, and presence/absence sensing. These applications are not limited to the aforementioned and many other functions can be accommodated. The PM-L25-C3is synchronized with a minimum operation frequency of 4 KHz, and can be operated in temperatures ranging from -25℃ to 80℃, and it can operate from 100VDC.

PM-L25-C3’s working principle can be described as follows. The infrared emitting element produces an infrared beam, and the receiver receives the beam after it has passed through the gap gap. The received light beam is then compared to an internally stored reference model, and an output corresponding to that comparison is sent to the integrated circuit. If the object within the gap is the same object as the model, the output of the integrated circuit will be "00" or "01".

The use of the PM-L25-C3 can provide a significant degree of reliability and accuracy in relation to the perceived functionality. Its high precision response times and reliable sensing systems help reduce the possibility of incorrect output. In addition, it features a high-isolation integral-conductive dust proof construction, ensuring its use in dusty environments. Overall, the PM-L25-C3 can provide an economical and efficient solution for sensing and identifying objects in a multitude of applications.
