    Linear scale for digital readout

    Linear scale for digital readout, milling machine, video measuring machine and profile projector.

    • Long-distance transmission: above 100 meters without any extra transceiver.
    • Five bearings in the sliding section ensure excellent repetitive positioning.
    • Multiple layers of insulated mesh and a soft metal protective outer shell applied to the signal cable ensure reliable waterproof properties and good anti-interference.
    • Made of special plastics, the dustproof slice is resistant to scratches, corrosion and friction.
    High quality linear scale

    Motion speed of linear scale over 60 meters per minute.

    • The anodized aluminum alloy scale body and chrome-plated scale end bring excellent anti-corrosive properties.
    • sisco linear scale has well-designed components to allow easy installation and maintenance. Good waterproof and dustproof properties contribute to a long lifespan.
    • Glass precision metrological grating is used as the measuring indicator of the sensor.


    The linear scale can be combined with the digital grating to form a grating measuring system for precise and accurate stroke measurement. It can also be used in the processing and measuring industries, such as lathes, milling machines, grinders, and EDM machines.

    Q1: What is a linear scale?
    A1: The linear scale is a measurement feedback device that works with the optical principle of the grating. The linear scale is often used in the closed-loop servo system of the CNC machine tool and can be used for the detection of linear displacement or angular displacement. The signal output by the linear scale is a digital pulse, which has the characteristics of a large detection range, high detection accuracy and fast response speed.

    A2: How does a linear scale work?
    Q2: This linear scale is a kind of transmission amplitude grating, and the principle is, when the opposite travel main grating and the subordinate grating occurs, the Moire grid/line is generated. This change will be transferred into an electric signal through the precise photo-electric exchanger, and then the digital signal at the relative travel is output after it is processed by the signal processing circuit.

    Q3: The requirements of the linear scale working conditions

    • Do not use the device in an atmosphere charged with inflammable gases. Do not use it in the condition of metal powder, oil, water or dust.
    • Do not disclose it in the bitter sunshine or high temperature. the ambient working temperature should range from 0℃~~40℃.
    • Be far away from the strong acid and alkalis as well as chemicals.
    • Keep the signal cable of the linear scale far from the power cords as possible.
    • Take the way of installation into consideration when using the device in situations of high voltage, strong current or magnetic field. do well in isolating the haphazard signals and avoid the disturbance of such.

    Tips for using a linear scale

    • Offer a proper match between the installation interface and the electric signal interface when designing and applying the device.
    • Do not lay heavy blocks on the signal cable. Please bundle and fix the excessive signal cable if it is overlong and do ensure the workers and the equipment a favorable working path.
    • Make sure that the plugs of signal cable are well and stable and plugged into the corresponding interface.
    • Design the application of the linear scale according to its effective travel range, and avoid the occurrence of surpassing the effective range and the damage of the device.
    • Do not let dust pile up on the linear scale and the read-head or the track of the moveable body of the linear scale.
    • Be sure to turn off the power before unplugging the connector of the signal cable.
