LinACE™ flat-board

InAxis Linear Absolute Magnetic Shaft Encoder

LinACE™ ﬂat-board is a board-level absolute linear magnetic encoder system designed for motion control applications as a position and velocity control loop element.

The readhead length only 30 mm and low weight of the encoder system make it suitable for applications with limited space.

LinACE™ ﬂat-board provides accurate measurements with excellent resolution and repeatability. The encoders are available in asynchronous serial over RS422, SSI and BiSS C output versions and offer a range of selectable resolutions from 10 μm to 0.5 μm with speeds up to 5 m/s. The position of the encoder is maintained even if the shaft rotates during forward and backward movement.
