MLX90394: Melexis announces the release

Meet MLX90394, Melexis‘ new position sensor suited for rotary, linear and 3D joystick control in gaming and industrial peripherals.

MLX90394: a brilliant new position sensor

It is a tiny Triaxis® micropower magnetometer, based on Hall-effect. It perfectly balances the design trade-off between low noise, current consumption and cost. With on-the-fly selectable modes and advanced configurability, it enables high reuse and fast time to market. This contactless solution is suitable for rotary, linear and 3D joystick control in gaming and industrial peripherals.
