What is the diameter of the sensor?

The threaded barrel you can see in the picture is 16mm in diameter. It also came with 2 screw-on collars and 2 rubber washers that fit around that threaded barrel. The washers are 22mm in diameter.

You sent me 2 sets of 2. The larger of the 2 fit but they both broke within days of use. I do not know the diameter.

The leads so not disconnect from the sensor or the alarm. You will need to drill a hole to fit the sensor through which would probably be about an inch.

Good question, they do give you a formula to figure out the rotational code to enter when installing the sensor. may need to find instructions to see size ranges.

I have several of these, but I don't have them with me, but I think the diameter is around 1".

The diameter is close to 4 inches. I think the description given is in error. This is the same size as the unit we had previously back in the '80s.

This is the size of the CCD sensor, generally the bigger the sensor the better. Do a little research as to why that is the case.

The cable that connects the sensor to the device is a standard phone cable. You just need to get a phone cable in the length you need. The maximum cable length that can be used is 100ft.

The sensor size is four thirds (4/3). This is a little smaller then the APS size and much larger the One Inch size. Techradar explains sensor sizes at this link: http://www.techradar.com/us/news/photography-video-capture/cameras/sensor-size-explained-1042035

The end of the sensor is plastic and 0.75 x 1.25 x 2.5" long if you did could not disconnect the wires you would need a one and a half inch diameter hole. If you could cut the wires and put the sensor in and then reattach it you would just need a small hole.

Sorry for the late response Sheila. It is approximately 3.75in. in diameter. Works well. I have not had any issues.

Sensor cable is about 3/16" diameter and lead to sensor cable is same as flat telephone wall cord.

Approximate overall length, width, and height of sensor and holder together, as pictured is: 1.75" L x 1.125" W x 0.5625" H

Here are the dimensions: 2 1/2" square x 1" depth. It is the smallest motion sensor I've found. It's a nice little unit if you can put up with the programming.

I don't remember the diameter but they were a good size... just never worked :)

6 inch diameter. I have had good results with this device on electric and gas burners.
