The diameter of the Amazon picture is 3.5 inches.
My circuit was made up of 4 of these that are connected to a 200 feet wire and instead of using the resistor, I just eliminated the resistor to be used. In this case, you do not need a resistor because the distance of the wire is what you are using it for. It might be helpful to
My package doesn't have any ratings. I looked at the actual parts and did not see any. As it happened, previous to this I had previously purchased a generic button from the hardware store that worked well on a window whose sensor was damaged and it functioned as it should- so I really never knew that mhz matters. It works fine with the ones I purchased recently A copy of it is on my front door. Even for the first installation of a hard wired system, I believe these will work either as replacements or as an upgrade. Likewise, I took a look at my old sensor, installed by the alarm company, and it also seemed rather I am sorry to say I cannot provide an exact answer to your question. There is no way for me to test mine.

I made a video for you. The order is for two packs of 10 for a total of 20 In total, six switches have a defect. Four of the defective switches need to be touched by the magnet to function. There is no 3/4 inch distance as described in the In two of the switches (40 and 14 ohms, respectively), the resistance never changes to 0 ohms when triggered. Because of these problems, a false alarm can be triggered by any small vibration or movement. The quality control in this product is not very good. The batch of 20 that I made has only 14 useful items. I have again provided a video for your review. The following steps will help you prepare for your own quality check before installation. The batch I just put out failed 30% of the time! There are 14 designs that pass the test effectively, and the design of the first is certainly impressive. A good amount of strength is provided by potting the wires. A 3/4" range between the magnet's face and the sensor detects its presence. Hopefully the electronics will work for a very long time. I would feel a lot better if this had a mark or certification from an agency or lab like UL, CE, or TgW.
When I received the order with 10 sensors I received only 4 magnets and one magnet per sensor was needed. It works, and fortunately there were some old magnets lying around that were good for the 6 sensors that did not come with Since the items were expensive, it wouldn't have been worth my time for me to return them.
I love how well they work. While smaller sensors are easier to install in small spaces, larger sensors would be easier in areas where drilling at an angle is necessary. This is because a 3/4" sensor hole would allow you to drill a 3/8" wire chase at an angle more efficiently. While 3/8" sensors can be great, you have to be careful to drill correctly, or you will have to repair it many times over. Ensure that the holes are sized correctly and then caulk or putty them.
I have been installing wired alarm panels for rental properties. I have no problems with it. The renters are to be particularly hesitant about stuff that requires battery maintenance or is easily touched. I have "handy" tenants, but they rarely mess with these because they are somewhat out of sight.
It would have been helpful if I opened up the sensors before the return window ended. Just got around to installing them this weekend! I bought them several months ago and haven't been able to use them until now!.
My alarm sub-system was 3/4" in size A poor job was done on the installation for my client by the contractor. A piece of electrical tape was used to hold the contacts in place in the slot of the doorframe. In addition. The doors came crashing down on them and they were crushed. The smaller sized contacts are installed by retrofitting a 3/4" hole in the frame with a plug that has a 3/8" hole drilled in it to enable the smaller contacts to fit. I'm very pleased with how this turned out.
Work is all done. Magnetic devices that come with them have a great deal of power. The switch must be closed about 3/4 of an inch away from the body. Then I bent the wires several times at the base, taking one at a time. As of now, the switch is still operational. As a result, they work perfectly.
The program worked in accordance with the description. There would have been nice to be able to choose from other sizes. I had to retrofit the holes because they were predrilled.
