Pull wire displacement sensor precautions:
1.The use of the bottom 4 fixing screw holes, according to the site and machine installation space facilities need, direct installation or additional protection or other mechanical use.
2. Stainless steel cable installation, must pay attention to the horizontal Angle, that is, as far as possible to make the cable from the outlet to the moving part of the mechanism, the horizontal slide during work.
3. Keep a small Angle (allowable deviation +/-3°) to ensure measurement accuracy and cable life.
The steel cable body is stainless steel and coated with fluorine layer, do not let it be hurt by external forces, burn, impact and other improper things: excessive dust, debris accumulation or enough to damage the steel cable stored in the internal pulley or wire outlet will cause damage to the steel cable, resulting in failure of operation.
4. Not installed in the workbench or fixed sitting, do not use hands or other products to pull out the steel cable and let it bounce back instantaneously. This will cause the cable to break and damage the body structure.
5. If used in the non-linear movement of the mechanism, please install the appropriate pulley operation.
6. If used in bad environment or special occasions, please install your own protection mechanism.
