Reflection optics.

It is a reflective optical sensor for a model railroad. The sensors must be positioned in the track axis. When the train is going above the sensor, relay contact switches the required circuits. (Crossings, road crossings, lightsignals) It is equipped with built-in voltage regulator, polarity protection, delay function. In addition, there are additional inputs that allow multiple sensors to be connected to perform certain tasks. Perfect panels. Nice work. Special thanks to Karen Linnak. I recommend!
