4. Installation Notes
Use the four fixing screw holes on the mounting bracket or base, and choose the correct installation direction according to the available equipment space.
During installation, keep the wire rope movement as straight as possible between the rope outlet and the moving point. The angle deviation should be minimized, with a recommended tolerance of about ±3°, to maintain measurement accuracy and rope service life.
For vertical long-stroke applications with heavier moving parts, it is recommended to place the sensor body at the lower side and pull the wire rope upward.
The wire rope is made of stainless steel. Avoid cuts, welding sparks, collisions, excessive dust buildup, debris, and corrosive environments.
Before installation is completed, do not pull out the rope by hand or with objects and allow it to retract suddenly, as this may damage the rope or sensor body.
For non-linear motion, use a suitable pulley or guide mechanism so that the moving path remains aligned with the wire rope.
Operate the sensor within the recommended motion speed and acceleration limits to ensure product reliability and longer service life.
