Mighty Mule ighty Mule/Linear 12-Volt Photo Eye Sensors-Pair (R4222), Black

ok

These here we could not get to work with the monitor in the house which we bought separately but these are totally different than the original ones we had purchased years ago

Not difficult to set up and still working 3 years later!

Since I first installed Mighty Mule products, it has been nothing but a constant stream of poor quality. As soon as I add a new item, the system had problems. Too many items on the system a customer service rep once said. But they were all their products. A wand to automatically open the gate on exit. Problems. The photo beam to protect the car from getting hit while the gate closes. Problems. The main board went out and I waited almost 2 years for a replacement. Now the system still doesn’t function. I want all products returned!

Exactly what I needed to go along with my gate. Good price.

Easy to install, easy to calibrate. works as described. Once calibrated and checked for proper function I used a bit of silicone to seal the upper area to further water proof this unit.

I am an electrical engineer and have been using previous versions of the product for about 13 years. In the last 2-3 years, the product quality has fallen off a clifff, to the point where the units they ship aren't even effectively quality tested when they leave the factory. This particular unit would not operate: the beam was perfectly aligned, but it would not trip the switch. I tried different time responses too. I've seen this before. This is the third unit in as many years. I will be looking for another manufacturer, because continuing with Linear is just a complete waste of my time.

I consider myself handy and do all my own tech, I installed the gate opener while back and decided to install the eyes, but after spending hours I couldn't figure out how to connect it to gate opener, and finally gave up.The instruction says about how to connect the cables to the eyes, but didn't say anything how/where to connect 6 cables to receiver.
