Wire Displacement Sensor / SM40-WY Wire Displacement Sensor

Application

The wire-pull displacement sensor is composed of a photoelectric collection part and a set of mechanical shell devices. The shell is made of aluminum alloy material, and the outer surface is oxidized, which is hard and wear-resistant; it can resist pressure and shock, and adapt to various harsh use occasions such as high temperature and high pressure; the reel is an original imported stainless steel wire rope, which is coated with plastic on the outer layer, has strong corrosion resistance, high strength, and no telescoping; the winding spring mechanism is made of imported stainless steel material, which is corrosion-resistant and stable in reeling. It makes it an industrial control preferred displacement sensor with compact structure, small installation space size, long measurement stroke, convenience and flexibility, and high-precision measurement.

This is a large-scale pull-wire (rope) displacement sensor, used to measure the linear distance of 0-20000mm. The product adopts the standardized CAN bus communication interface, which is durable and especially suitable for short distance and high resolution occasions.

Features

This product is easy to install and has a spare installation reference surface with multiple options according to needs; small installation space and low installation difficulty; no guide is required, and mechanical tolerance does not affect the measurement accuracy; it is widely used in linear guide systems, hydraulic cylinder systems, telescopic systems, storage position positioning, pressure machinery, papermaking machinery, textile machinery, metal sheet machinery, packaging machinery, printing machinery, level controllers, construction machinery and other related dimensional measurement and position control; it can be connected to PLC or secondary instruments, single-chip microcomputers and other acquisition systems.
