PM-R45 slot type photocouplers are 4-pin logic output type photointerrupters. They are designed using an infrared LED and a phototransistor and are intended for the detection of black marks, holes or slots in transparent or reflective materials. The PM-R45 is designed to operate in most industrial environments with an operating temperature range of -25°C to +85°C and an isolation voltage of 2000VRMS.

The PW-R45 Logic Output slot type photointerrupter consists of an infrared emitter and a phototransistor mounted in a housing. The infrared emitter sends infrared light through the slot in the housing and the phototransistor receives it. When the slot is blocked, the reception of light is prevented, and no current can flow through the phototransistor. When the source of light is blocked, the reception of light is blocked and the phototransistor is turned off, resulting in a logic "0" output. Conversely, when the slot is clear, light enters and is received by the phototransistor, which then turns on and sends a logic "1" output.

The PM-R45’s key features include excellent optical performance, low power consumption, fast response time, low cost, and high insulation voltage. They can be used in a wide range of applications including optical pulse detection, touch switch, automatic vending, or scene surveillance applications.

The PM-R45 has a wide range of uses. It can be used in industrial controls for motor or encoding sensing, in consumer Electronics for touch controls, locking mechanisms, power switch sensors, or in medical systems for sterilization control and physiological sensing. It is also ideal for use in office automation for counting paper, ID cards, or optical disk drives.

In addition, the PM-R45 can be used in remote sensing applications such as light sensing, temperature sensing, motion sensing, or sensing of presence (a person or an animal). It is also suitable for use in robotics for edge following or object detection.

The PM-R45 uses a simple photo-interrupter architecture and is very reliable. It is low cost, easy to install and configure, and is capable of handling data transmission speeds from 100kHz to 2MHz. It has excellent optical performance and is suitable for use in a variety of applications. Its small size and low power consumption make it ideal for use in small spaces or embedded systems.
