[0002] A pull-wire displacement sensor is a displacement measuring device that converts mechanical motion into electrical signals. It is commonly used in linear guide systems, hydraulic cylinder systems, telescopic systems, etc. The stroke of the hydraulic cylinder needs to be measured before use, and the pull-wire displacement sensor is used to accurately detect and control the stroke of the cylinder piston rod in the hydraulic cylinder displacement detection. The pull-wire displacement sensor is usually installed at the tail of the cylinder, and the wire rope is installed at the tail of the piston rod. When the wire rope is in a fast-rope-out condition, due to the high speed, the wire rope may break, the coil spring may deform, or even the encoder reading may fail, resulting in the wire rope breaking inside the cylinder, causing internal damage to the cylinder.

[0003] A Chinese patent application with application number CN202311413432.0 and application date October 30, 2023 discloses a self-protecting rope-drawn displacement sensor and a method of use, which effectively solves the problem that the wire is not superimposed on the winding wheel in the set manner during the wire displacement process, causing the linear proportional relationship between the wire displacement and the angle change value to change, increasing the measurement failure rate, and affecting the positioning stability. The wire rope of the rope-drawn displacement sensor has a large reeling force, causing harm to the user, and the deceleration effect decreases due to wear of the deceleration component, causing damage to the components inside the device, including an encoder, a box body is provided on one side of the encoder, a fixing plate is provided at the bottom of the box body, a shell is provided on one side of the box body, a wire take-up assembly is provided inside the box body, the wire take-up assembly includes a wire arrangement assembly, and deceleration assemblies are provided on both sides of the wire take-up assembly. A wire inlet pipe is provided on one side of the box body. This scheme makes the displacement sensor more stable and safe during use, but the above scheme does not solve the problem that the rope-drawn displacement sensor is prone to damage to the inside of the cylinder when performing stroke measurement.
