50 Ft. Driveway Vehicle Sensor (FM138) for Mighty Mule Automatic Gate Opener , Black

I use this for my Mule gate opening system. It is of very good quality and very heavy. The cord is very long Id say 75 feet. It works well and connects directly to the system. The price is a little high nut there arent many other options so its hard to complain. It was easy to install.

This gate sensor works great, so much better than having to dig for the remote!!

Paired nicely with my mighty mule gate opener. First one was only 50 ft and after so many years outdoors the squirrels finally killed it.

North Shore Commercial Door did an excellent job in shipping the product to me and I received it ahead of the estimated day of delivery. Unfortunately after I installed it, the product did not work. Rather than contact North Shore, I contacted the manufacturer (Gates that Open) directly for troubleshooting and customer service. After spending an hour on the phone with tech support (Mr. Andrew Zubr), we determined that the sensor was faulty and would have to be replaced. I sent Mr Zubr a copy of my invoice from North Shore and he had a replacement on the way to me the next day, he also included a prepaid return label to send the faulty sensor back to GTO. Even in light of the problems I had with the product, I give this review a 5 star rating because of the excellent customer service I received from the manufacturer. GTO does not sell direct, but distributes their products through many different vendors such as North Shore, however they back up their product 100% and have one of the best customer service and tech support divisions of any company with whom I have ever dealt.

This was a replacement for one that I had installed in 2009. It apparently went bad due to water. I noticed the old one had a small board that hooked between the yellow wire and the black. The new one did not come with one. So I hooked it up per the diagram and it worked fine except I noticed later in the day it was opening without a car there, in fact it was opening all the time. Reading the reviews, I noticed that one customer had the mule co send him a small board that went between the yellow wire and the black. I hooked my old one back up and the gate triggers fine with a car and no false openings. I measured the variable resistor and it is a 500Kohm pot. Mine was adjusted halfway at 250K ohms. So anyone with the falsing problem could get a 500K pot and set it for their own needs, about halfway. The other thing is that these units do not appear to be 100%waterproof. For $120, I want the thing to last a long long time. So I suggest that people use some silicone RTV caulking to seal the little hole that the wire goes into. Even better is to seal the whole unit into a piece of PVC pipe. Check the photos.

Simple instructions to follow and once installation was completed the gate worked on our first try

This seemed a bit pricey to me, but it is very well built and works perfectly, so you get what you pay for. I connected it to a Gatexpert AT1350 sliding gate opener and it works perfectly. The cable is heavy duty and suitable for direct burial, but I put it in PVC conduit anyway to ensure no issues. The hook up is straight forward, just 4 wires. Trenching 12" deep is the hardest part, but that would be necessary for any quality vehicle sensor.

Heed the warning of others, this product has a tendency to fail. To install correctly this takes a good amount of work and cost, conduit. It worked great for a few months and then started to fail, and in no time it completely failed. Installed as per instructions with no alterations. I've not contacted Mighty Mule about this issue yet. I will, and will report back their response.
