Installation Guide
The figure below shows where WxS8800 Ext-021CM is mounted on any flat and solid surface without a bracket. The cover contacts the surface and is fixed by four flat head screws:
Mounted on the wall Mounted on the pole
The following types and dimensions of flat head screw M4*20 are recommended for using on the rear cover of the sensor:
The figure below shows that the installation guide of WxS8800 Ext-021CM in manhole cover scenarios (need M4 flat screws, bracket, M6 expansion screws).
Bracket：
On the MC (manhole cover) application, the switch sensor needs to be fixed on the side wall of the MC, and the switch sensor fixing bracket below is needed：
The following types and dimensions of stainless steel screw M6*25 are recommended on the bracket:
The Sample Application
l Manhole
cover
The limit switch
is installed under the manhole cover, which can sense the vibration of the
surrounding environment and avoid false alarm. After the manhole cover is
removed, the normally open switch to normally closed, the power consumption
pole; When the cover is closed, it can be ensured that the cover is in good
condition.
l
l Harbour bridge crane
It is used to detect the position of the crane cab in motion and the switching state of various doors and the running state of the inner track on the crane
l numerically-controlled machine tool
Limit switch is widely used in all kinds of machine tools and lifting machinery, to control its travel, terminal limit protection, such as metal processing equipment, press, transmission machinery and special equipment.
