M18 retro sensor, 2.5mtr sensing, 2mtr lead
These electronic devices, photoelectric sensors or photocells, use the light emission principle combined with the electronic and are made up of an emitter or luminous source, the light rays of which 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 used is either infrared or red. By making use of this light various type of photoelectric sensors can be made. The AECO photoelectric sensors available the FT18 and FTQSP series in direct reflection, with reflector with polarized light and emitter-receiver versions. Due to their flexibility regarding the various standard programmable versions these products offer the possibility of stocking reduction and are easily interchangeable with most of the units available on the market. They are used in the field of automation to check for the presence, counting, position control, etc..., and they are compatible with most logic programmers.
