RLS: Rotary Magnetic Ring MRA049AF025EMH00

AksIM-2™ is a non-contact high performance off-axis absolute rotary encoder designed for applications with limited installation space. The compact, low profile readhead detects and evaluates the magnetic field of a thin, axially magnetized ring.

A hollow ring, true absolute functionality and high-speed operation make this encoder suitable for many applications. The AksIM-2 encoder system consists of an axially magnetised ring and a readhead. The encoders are equipped with BiSS, Asynchronous serial (UART), SPI, PWM or SSI communication interfaces and offer a range of binary resolutions up to 20 bits per revolution.

The AksIM-2 encoder operates in a temperature range between -40 °C and +105 °C and is highly resistant to shock and vibration. It has a built-in advanced self-monitoring function that continuously checks several internal parameters. Error reports, warnings and other status signals are available on all communication interfaces and visualised with the on-board LED. The AksIM-2 encoder system is suitable for use in industrial and medical applications. A typical application is a robot arm joint with a cable feed through the ring, or a precision gearbox where the ring is mounted on the main transmission shaft. A custom design service for OEM integration is also available
