LinACE™ absolute linear shaft encoder

LinACE™ absolute linear shaft encoder

More Views

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.
