Miller Edge ME120 5 foot with aluminum mounting channel.
When touched, these pressure sensitive edges immediately send an electrical signal to your controls to stop, and/or reverse operations. Designed for use in a wide variety of applications, these Sensing Edges are extremely durable and can be used indoor or out. They are resistant to water, flame, and common greases and oils.
Edge sensors work good when used properly. Old one's failed because they were mounted vertical with the cord entrance up. Ran entered and soaked the internal parts that were supposed to be sealed. Make sure you seal the cord entrance or mount them cord entrance side down. New parts work great.
