Optical Sensor (transmissive Photoelectric switch) ?? WHAT ??? OPTICAL SENSORS Photoelectric Sensors (Photoelectric Sensor, PES), essentially because they are made up of photovoltaic components. When light shines on the appropriate surface of the optical sensor, we will change the nature. Optical signal is converted into an electrical signal by the phenomenon of electron emission from the cathode (cathode) when there is an amount of light in. The use and role of optical sensors? The use of optical sensors primarily is used to detect many different body types, from the discovery of a plastic bottle on the carousel or check robot hand was gripping automotive components to install or not.? sensor plays a very important role in the field of industrial automation. Without optical sensor makes it hard to get automated, like work, but could not see it. The glow? Today optical sensors typically use semiconductor light LED (Light Emitting Diode).? Light are emitted in pulses. Rhythmic pulse special sensors help distinguish light sensor and light from other sources. ?? Collectors morning? Usually light collector is a phototransistor (optical transistors). The department feels light and converted into an electrical signal proportional output signal circuit ??? The circuit output signal transfer rate (analogue) from optical transistor / ASIC signal On / Off is amplified. When the amount of light collected in excess of the threshold is determined, the output signal of the sensor is activated
