This particular photoelectric sensor uses infrared light. When an object breaks the light beam or reflects it back, the sensor's internal circuitry triggers a change in its output, acting as a proximity switch. This allows for automated detection in various industrial and commercial settings, providing reliable object sensing over its 4m sensing distance. 3 Main Types of Photoelectric Sensors There are three primary types of photoelectric sensors, each suited for different applications. The first is through-beam, where the emitter and receiver are in separate housings. The second is diffuse-reflective, where the sensor emits light and detects reflections directly from the object. This product is an infrared mirror reflective type, which means it requires a reflector to bounce the light back to the sensor. Common Applications Photoelectric sensors like this model are widely used in industrial automation, material handling, and safety systems. Their ability to detect objects without physical contact makes them ideal for applications such as counting items on a conveyor belt, monitoring product flow, or positioning machinery. The 4m sensing distance makes it suitable for detecting objects across a moderate span, while its AC/DC 90-250V operating voltage offers flexibility for various power supplies. The Core Components A photoelectric sensor fundamentally consists of three main parts. Firstly, the emitter, which generates the light beam – in this case, infrared light. Secondly, the receiver, which detects the emitted light. Finally, the output circuit, which processes the detected light and provides a signal, acting as a proximity switch. These components work together to sense objects over the 4m sensing distance, operating reliably within the 90-250V AC/DC range. The 3 Main Operating Modes Photoelectric sensors typically operate in three main modes. The first is through-beam mode, where an object interrupting the beam is detected. The second is diffuse-reflective mode, where the sensor detects light reflected directly from the object. This specific product, the E3JK-R4M1, operates in infrared mirror reflective mode, meaning it requires a retro-reflector to bounce the infrared light beam back to the sensor. An object breaking this reflected beam triggers the proximity switch.
