About Photoelectric Sensors

A photoelectric sensor is an electrical device made up of an emitter and a receiver. The emitter gives off a beam of light at a specific intensity and direction, and the receiver picks up that light signal and ignores other ambient light. By giving off light at a specific frequency, the emitter can ensure that the receiver does not confuse any other light source for the emitter.When the beam of light between the emitter and receiver is broken, the sensor is alerted. Depending on the use of the sensor, there can be many different ways in which this information is used--but what's important is that the sensor knows as soon as anything passes between its two parts. There are many commercial and industrial uses for photoelectric sensors.Photoelectric sensors are frequently used as security devices, since they can be placed in front of a door, and sound an alarm when the light is broken. Photoelectric sensors are also used in grocery store conveyor belts, so that items are brought down the belt, but that they stop when they reach the cashier. There are even novel new smoke detectors that use photoelectric technology!You can use photoelectric sensors in any number of ways. They are safe, quiet, and accurate--which is why they are often part of factory machines that need to do precise work. Let your imagination run wild, and be the next to find a great new way to use this cutting-edge technology.
