Optical sensors play a key role in industrial automation, improving accuracy and productivity of production and measurement processes in most industries. Photointerrupters with Slot Type and Transistor Output are used in applications where it is desirable to detect a light beam interruption without contact or mechanical wear. The PM-R24-R Photointerrupter is an ideal solution for these kinds of applications.

The PM-R24-R Photointerrupter consists of an optical emitter and detector in the same housing. The screw terminal actuator is mounted between the emitter and detector assemblies and actuates when the light from the emitter is blocked. The PM-R24-R has a light irradiation angle of +/- 20 degrees, and a detecting distance of 5.5 mm. It has a trigger voltage of 12V and a maximum photocurrent of 10mA.

The PM-R24-R has been designed specifically for use in applications where it is desirable to detect a light beam interruption without contact or mechanical wear. Common examples of these applications include, but are not limited to, safety sensors for industrial equipment, paper guides and web guides, mark reading and position detecting systems, and verification systems.

The working principle of the PM-R24-R is based on the interruption of a light beam which is generated by the embedded emitter in the device. When the light beam is blocked, an electronic signal is produced which is detected by the embedded photodiode. This signal can be used to signal that the beam has been blocked. The PM-R24-R utilizes a transistor output for the detection of the interruption.

The transistor output serves as an interface between the PM-R24-R and the electrical output of the system. The output device provides logic compatibility with most standard control and logic systems. The output of the device can be either directly connected to external circuitry or sent through a transformer to reduce the output load and increase the operational life of the device. The output can be either of two types, either NPN or PNP, depending on the current status of the beam interruption.

The PM-R24-R is a reliable device that has been designed for many industrial application environments and for operation in ambient temperatures ranging from -20°C to +60°C. The device incorporates various electronic protection features, such as power surge protection, overcurrent protection and reverse-polarity protection, to ensure reliable operation even in harsh industrial environments.

The PM-R24-R Photointerrupter is an ideal choice for detecting a light beam interruption without contact or mechanical wear in applications such as safety sensors for industrial equipment, paper guides and web guides, mark reading and position detecting systems, and verification systems. The device’s transistor output provides logic compatibility with most standard control and logic systems, whilst the various electronic protection features ensure reliable operation even in harsh industrial environments.
