Excellent Industrial Contact!
Submitted on 04/22/2020 Alarm Grid

The Honeywell MPS51C is an overhead door contact that has since been discontinued. However, if you come across a used model somewhere, don't be afraid to give it a shot. These are high-quality, long-lasting contact sensors that are specifically designed to withstand the rigors of industrial use. You can expect this sensor to withstand repeated use, even in the most demanding of settings. It is great for use on overhead doors, garage doors, and more. We really like this sensor, and we give it a perfect 5 Star rating.

Hardwired door contacts like the Honeywell MPS51C are extremely simple and effective devices. They are very easy to wire, and they can be readily used with wireless transmitters if needed. Remember, a wired contact is a purely mechanical device that does not require any electricity. This makes them very straightforward and easy to set up. For added durability, the wire leads are encased in 24" armored cable. This is a Form C contact, meaning that a NO or a NC wiring configuration can be used. We also appreciate the fact that this contact allows for a large magnet spacing gap of two (2) inches. This makes it suitable for more industrial applications, including for use on overhead doors and garage doors.

There are not many downsides to the Honeywell MPS51C. One issue is that it is discontinued, and it can no longer be purchased new. You will likely only find used models elsewhere. There are plenty of newer models available. But with this being an extremely simple device, don't expect the newer models to really offer any flashy upgrades. We must also admit that the design of the Honeywell MPS51C is somewhat dated and ugly. But for industrial use, that isn't very important. Overall, this an outstanding industrial grade contact, and you will not be disappointed with its performance. It gets 5 Stars from Alarm Grid.
