Optoelectronic sensors have the longest range of all types — from a few centimetres to tens of metres. You will find three basic designs here: a diffuse sensor needs only one side and monitors the object directly in front of its face, a retro-reflective sensor works against a reflector and covers several metres, and a through-beam barrier with separate emitter and receiver units is the most reliable and reaches furthest. The range includes cylindrical and block designs, models with background suppression for precise definition of the working zone, red and infrared LEDs and laser sensors for small objects. You can choose by PNP or NPN output, light-on or dark-on switching, degree of protection IP67 and connection by cable or M8 and M12. connector. We supply sensors from Lanbao, TECHNOLINE, SICK, Balluff, IPF, IFM and others. If needed, contact us and we will be happy to help you choose the right type for your application.

Photoelectric Sensors
Optoelectronic or optical sensors use light for non-contact detection of objects. The sensing principle is essential for selection: a diffuse sensor works with reflection from the object, a retro-reflective version with a reflector, and a through-beam barrier with a separate emitter and receiver.
How to choose an optical sensor
Compare the range, light spot size, colour and surface of the object, background suppression, response speed and the output for the control system. For transparent or shiny objects, verify the suitability of the specific model for this application. Choose optical fibres and their amplifiers as a compatible assembly.
For the connection, check the supply, PNP/NPN, switching function, number of wires and connector wiring. A standard optical sensor does not replace a safety light curtain designed for personnel protection.
