Product description

The MLX90514 is a dual-input inductive encoder for absolute rotary or linear motion sensing. It is suitable for robotic & industrial applications where the simultaneous measurement of two positions is required. The position information derived from the two channels can be directly transferred to the output or used for the calculation of a 16‐bit Vernier angle.

The MLX90514 is designed to control an inductive sensor system formed by the transmitting coil, one or multiple targets and two sets of receiver coils, each composed of three receiver coils. The on‐chip LC oscillator generates an electromagnetic field together with the transmitting coil. This electromagnetic field induces, via the target(s), angle-dependent voltages in the receiving coils. These signals are captured and processed by the MLX90514 internal DSP units according to the device configuration.

The MLX90514-robotics (robotics & industrial automation) offers multiple output modes. An SPI protocol allows fast protected data transfer and device programming. The SSI enables fast data output with a 2‐wire connection.
