Review: Metal sensor for attachment for Mule - 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.
