    LA11 ABSOLUTE MAGNETIC ENCODER SYSTEM

    pdfLA11 ABSOLUTE MAGNETIC ENCODER SYSTEM.

    LA11 is an absolute magnetic linear encoder system designed for motion control applications as a position and velocity control loop feedback element. The encoder system is highly reliable due to contactless absolute measuring principle, built-in safety algorithms and high quality materials/components used.
    The measuring standard is a magnetic scale which consists of a stainless steel substrate with an elasto-ferrite layer. The elasto-ferrite layer is magnetised with two tracks. The incremental track is magnetised with 2 mm long (alternating south and north) poles and the absolute track is magnetised with a pseudo random binary sequence (PRBS) absolute code with 13 bit length. The elasto-ferrite layer is immune to chemicals commonly found in industry.
    The readhead includes Hall sensor arrays for PRBS track reading, an AMR sensor for incremental track reading, interpolation electronics and custom logic circuitry. The data from the Hall arrays and interpolator are processed in the internal MCU using special algorithms to determine the absolute position.
    The electronics design provides short response and recovery times. Diagnostic information is available through a serial communication channel and status LED.
    For applications which demand that the AS scale can be removed easily please consider TRS track system.

     
    LINACE™ ABSOLUTE LINEAR SHAFT ENCODER

    pdfLINACE™ ABSOLUTE LINEAR SHAFT ENCODER.

    LinACE™ is an extremely robust absolute linear cylindrical encoder system designed for integration into hydraulic, pneumatic and electromechanical actuators as a feedback element for position/velocity closed loop applications.
    Absolute position (no battery back-up needed) can be provided in a range of outputs (BiSS, SSI, PWM and serial RS422) at a range of selectable resolutions down to 0.5 µm with velocities up to 5 m/s. The encoder shaft is impervious to external magnetic fields and may be rotated as it moves forwards and backwards without loosing position. The encoder readhead operates from -30 °C to +85 °C.
    The encoder module is available for OEM applications. The readhead housing, shaft diameters and shaft end attachment holes are customisable.
