The application field and working principle of the E3FR-LS86H Photoelectric Sensor refer to its ability to detect object presence, absence, and distance in an industrial setting. In a light-on type photoelectric sensor, an infrared emitter sends light to a target object. When the beam of light is blocked, the sensor’s output circuit turns off, indicating an object is present. This type of sensor is commonly used in industrial applications such as conveyor belt monitoring, presence and absence detection, and object counting.

When an item blocks the emitted light beam, a light-on type photoelectric sensor sends an output signal to a controller. This signal can be interpreted as a digital binary on/off type of signal, or as a DC voltage or current signal. The DC signals can be interpreted as being proportional to the distance of the object in relation to the sensor’s active area. This feature gives the operator a wider range of sensing applications, such as distance measurement, sensing of the presence of an object, and the amount of material present.

The E3FR-LS86H photoelectric sensor consists of an infrared emitter and an IR receiver. The emitter emits an infrared signal in a specific direction and the receiver detects that signal when it is received from a target object. The E3FR-LS86H features a long sensing distance up to 1 meter, narrow visible beam for a range of up to 7 meters and an adjustable light-off delay, which guarantees almost no false detection even in random ambient light. It also offers a high-speed switching time, a wide temperature range, and a high-resolution sensing capability all in a compact package.

In addition, the E3FR-LS86H photoelectric sensor features an innovative dual-beam system, which helps to protect the sensors against random ambient light. The dual-beam system consists of two infrared emitter receptors, which send out a narrow beam of IR light to the target object. When both beams are blocked, then the sensor output is turned off, indicating an object is present. This system ensures that ambient light will not trigger the sensor, reducing false detections.

The E3FR-LS86H photoelectric sensor is ideal for a wide range of Industrial and commercial applications such as machine vision, automated material handling, and process control. It is designed to withstand harsh industrial environments, while providing a reliable, accurate, and cost-effective solution for object detection and sensing.
