A photoelectric sensor has two parts, an IR emitter and receiver(photodiode). When an object falls between the emitter and receiver, the photo diode gets triggered - normally a digital signal (5v usually). This can be connected to the digital input of a PLC.
Let me know for what application U want? I am an Application Engineer designing & Developing Instrumentation Applications using BANEER (USA) & TURK (Gernmany) Make Photoelectric sensors.
I'm working on a scorbot-er III. My project is to discard the controller unit and build it up using Hitachi PLC EH-150. I've encountered problem using the photoelectric sensor. Where can I source for the info of the photoelectric sensors for this robot with regards to its input voltage requirement and how to make these photoelectric diodes function.
