There are two ways to measure gaps and clearances: direct measurement using an optical thrubeam sensor and indirect measurement using a contact-type sensor or eddy current sensor with a dog.
The choice of the optimal model depends on the installation space and required accuracy. For more information, contact your nearest KEYENCE sales office.
