Plastic roller type (Custom made) :
50mm rubber’s roller type(Custom made): 50mm
Metal roller type( Custom made)
OVERTRAVEL TYPE :
The Overtravel Type is a limit switch which is provided with a greater OT to facilitate dog setting.
Since this type is indentical to the Basic Type in dimension, both types are interchangeable.
The Overtravel Type is classified into two versions -71 series and -72 series
The head of -71 series switch can be installed in any of the four directions : 45X operation on either side-possible
The head of -72 series switch can be installed only in two directions, forward and backward : 90X operation on either side-possible
ROTARY ACTUATION :
