Overview
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.
Features
- Small footprint 30 × 25 × 8.5 mm
- Resolutions up to 0.5 μm
- Measuring lengths up to 300 mm
- Absolute position at power-up
Benefits
- Built-in self-monitoring
- Excellent resistance to stray magnetic fields
- Stable over whole temperature range
- Suitable for highly dynamic control loops
- Non-contact technology for high reliability
