Optical sensors are used in many fields and are designed to detect the presence of objects or changes in light levels. One type of optical sensor is a photointerrupter, which detects the passage of an object between a light source and a light detector, such as a slot-type transistor output (PM-K24-C3).

PM-K24-C3 photointerrupters have a slot-type structure with an LED light source, an optical transmissive arm, and a transmissive type output (collector or emitter) in the form of a PC board terminal. These devices detect the interruption of the light beam within the slot by an object placed between the light source and the light detector. When the light beams are interrupted, the transistor output turns off and the signal is output. These sensors are widely used in the manufacture of auto parts and industrial machinery.

The PM-K24-C3 photointerrupter is typically used for sensing the movement of objects, or for counting specific objects such as coins or paper currency. These devices are also used for controlling conveyors, detecting rotation speeds, and overall controlling an industrial process. They are designed to be capable of operation in a wide temperature range, and can handle high vibration levels.

The working principle of the PM-K24-C3 photointerrupter is based on the interruption of the light beam path between the LED light source and the light detector. When the light beam is interrupted, the transistor output is activated and a signal is emitted. The output state is reversed when the light beam is restored.

The light illumination and detection angles of the PM-K24-C3 photointerrupter can be adjusted depending on the application. The selection of the optimal illumination and detection angles is important for the proper operation of the device. It is possible to adjust the optical axis of the LED light source and the optical transmissive arm to match the angle of the object to be detected.

The PM-K24-C3 photointerrupter features an optically isolated design which eliminates the need for a separate isolation device, providing an advantage over other types of photointerrupters. It has a detection range of up to 7 mm, with a response time of less than 0.5 ms. It has an operating temperature range of -40 to 85°C and is IP67 waterproof. It is also RoHS compliant and UL recognized, making it suitable for a wide range of applications.

The PM-K24-C3 photointerrupter is a versatile and reliable device that can be used for detecting the movement of objects or counting specific objects. It features an optically isolated design, adjustable light illumination and detection angles, and is capable of withstanding a wide range of temperatures and vibration levels. This makes it suitable for a wide range of applications in the automotive, industrial, and other fields.
