Photoelectric Sensor Solutions

Photoelectric Sensors Photoelectric sensors can detect the presence or absence of objects or changes in surface conditions of a target. They emit a beam of light that is detected by a receiving element. When an object interrupts or reflects the emitted light, an output switches, sending an electronic signal. Most target materials can be detected including shiny, dark, clear, or multicolored ones. Photoelectric sensors are very common in industrial manufacturing fields such as material handling, packaging, food and beverage, medical, and many others. Photoelectric sensors can be long range,...

Excess Gain Sensing Beams Excess gain is a measurement of the amount of light energy detected by the receiver element. A sensor needs an excess gain of one to cause the sensor's output to switch "on" or "off." However, contaminants in the sensing environment such as dirt, dust, smoke, and moisture can cause signal attenuation, so more excess gain will be required receive a valid signal. Excess gain may be seen as the extra sensing energy available to overcome that attenuation. Visible LEDs An excess gain chart shows how much light energy is available at a given distance. The dirtier the...
