What are Photoelectric Sensors?
Photoelectric sensors use the light emission principle, electronic properties, and an emitter or luminous source. The light rays of the luminous source are detected by a receiver. The variation in luminous signal, obtained when interrupting this ray, is converted into an electrical signal, and is measured and used by an electrical circuit.
The light being used is either infrared or red. By making use of this light, various types of photoelectric sensors can be made.
The AECO photoelectric sensors available are the FT18 and FTQSP series with direct reflection that offer versions with reflector with polarized light or emitter-receiver. Due to their flexibility regarding the various standard and programmable versions, these products are easily interchangeable with most of the units available on the market.
