Fastening of the switch cable
The switch bodies are filled with resin for sealing purposes. To avoid stressing the cable and switch body, fasten the switch at 5 cm or farther away from the switch body, should the wire be bent, the bending radius shall be at least 45mm. |
Switch bank mounting
A maximum of six switches may be mounted together as a switch bank. During the installation,the convex part of the switch back.The mounting panel shall be 6mm or thicker. |
 |
 |
|
Installation The service life and accuracy of switches will be effected by the shape of actuator operation frequency & over travel. So the angular of the fixing level should be about 30, the surface finish of the fixing level should be over, the hardness is from HV400~500.When installing, the position of the concave part should be above the standard panel |
Installation
Recommended tightening torque according to the follwing form.
