I'm using this for a gate clearance sensor. When the oil or UPS delivery trucks leave, their rear ends of the trucks gets into the way of gate closing. I don't want to use photo beams due to snow storm interference. The sensor is two feet past the gate toward the highway. Since the gate controller is very close, I bought a steel electrical pull box at Home Depot and coiled the extra wire in it. Since the sensor is a hysteresis (magnetic) sensitivity device, I didn't want to cut the wire and affect it magnetically. Also the steel pull box will prevent the coil of wire inside from being affected by the sensor. I grounded the box and the negative side of the battery where the shield braid in the sensor cable is connected. This allows any electrical or galvanic currents to leak away. It has been working reliability. The gate closing time is held up until the truck is past the gate area. The sensor's black and blue wires are connected to, COM and SAFETY terminals on the FM500 gate controller.

Rated 1.0 out of 5.0 by Warrior55 Stopped Working for No Reason
It worked very well for the first two months or so. Then late on a Sunday afternoon it stopped working. I thought it was something with the batteries or power to the gate itself. Its not any of those things. Ran a continuity test on the line to the sensor as well. Nothing wrong with it, other than it stopped working. I am going to have to dig it out and return it. We get by with the remotes now, but its nice to get in your car and back out without fumbling for the remote . . . . . .
If you check this page, you will see a similar situation from March of this year.

Installed it. Buried it and it does not work right. Opens gate all day long. About every 10 minutes. Trying to get mighty mule fate opener to replace it

This thing has a mind of it's own! The gate will randomly open. I've tried several different things, including placing 2 ft underground...nothing works.

Love this product.. wish I had purchased it long before now! Take my advice, read the settings on the inside panel of your gate opener first about where to put it on the board. But once hooked up, it is one of my best purchases ever!

Don't strip the wire. It is very thin. It does work well. I like that you don't have to keep a remote around.
