Proximity Detection - Sensing Applications
> Home > Applications > Proximity detection
|A very common application for a
sensor in the industrial sector, a proximity sensor simply detects when
something comes into its proximity. Such a sensor, which gives a switched
output on detecting something coming into proximity, is called a proximity
There are standard proximity switches of many types on the industrial market
today for general applications, including inductive, capacitive, optical, and
ultrasonic types. Techniques will be more or less suitable depending on the
target you want to detect and other environmental conditions of your
application. Click here to
see our comparison of sensing techniques.
Sensatech have not involved themselves in standard proximity switch
manufacture which in some cases is presently a commodity type product, rather
Sensatech concentrate on custom proximity switches where a standard switch is
not available to solve the particular application.
Normally such a device would use the capacitive or electric field sensing
technique, which is a Sensatech area of specialist expertise, but this need not
be the case. If you have an application where proximity detection is required
and cannot find a suitable standard device, please do
contact Sensatech with your enquiry.
If the volumes of your requirement are sufficient you may not end up paying
much more than would have been the case with a standard unit, even while
getting a custom sensor.
