The Honeywell 5811 Has Been Discontinued

Honeywell has discontinued the 5811 sensor and magnet. This popular sensor is the unit that has always been sent out with our most popular kits. It has been replaced by the Honeywell 5800MINI, a smaller, slightly sleeker device with a number of added benefits and improved range.

While not as common in the field as the 5816, the 5811s have, to date, been the contact that anyone looking for a small profile unit have purchased. And while not as thin as the 5820Ls, which are perfect for applications where a window has a very small lip, the discreet 5811 sensors are a well-loved mainstay of the Honeywell line. We are sad to see them go, but are excited about the new 5800MINIs that have replaced them.

For those ordering kits, our images show the old sensor. You will, however, from now on, be receiving the 5800MINIs. We'll be replacing the product shots in short order, but for now, please be aware of the change.

Unfortunately, for those looking to replace old 5811 sensors with new 5811 sensors, we are completely out of stock as is Honeywell. The new 5800MINIs should suffice.
