Optical Sensors (transmissive Photoelectric switch) SENSOR is? Photoelectric sensors (Photoelectric Sensor, PES), essentially they are by the photovoltaic components form. The appropriate light shining on the surface of optical sensors, they will change the properties. The optical signals are converted into electrical signals by virtue of electronic emission phenomena in the cathode electrode (Cathode) when there's a light shining on.The function and role of the optical sensors of optical sensors are used to detect a variety of different objects, from the discovery of a plastic bottle on the conveyor or check if the robot has to remove automotive components to install or not. Optical sensors are very important role in the field of industrial automation. If no sensor is hard to get automation, like working without that.The glow is today commonly used optical sensors in semiconductor lighting LED (Light Emitting Diode). The light emitted by the pulse. Special pulse rhythm helps sensors distinguish the light sensor and light from other sources. The usual morning collector collector is a phototransistor (optical transistors). The Department felt the light and converted into electrical signal output Circuit ratio output signal transfer Circuit ratio of analogue from transistors/optical signal ASIC On/Off are amplified. When the amount of light collected exceeds the defined threshold, the output signal of the sensor is enabled
