New 18-bit absolute magnetic ring encoder

Paul Boughton

Renishaw's associate company, RLS,  has announced the availability of the new AksIM true-absolute magnetic rotary encoder for embedded OEM motion control applications.

Available through Renishaw's worldwide network, AksIM has up to 18-bit resolution and zero mechanical hysteresis in a unique through-bore configuration which sets a new standard for magnetic encoder performance and value.

AksIM comprises a low-profile encoder readhead and a separate magnetic ring with an impressive price-performance ratio. The readhead is available either in a fully sealed IP64 housing or as a board level encoder, supporting a range of data output formats including serial RS422, CAN, SSI, PWM, I2C, SPI and USB with binary resolutions to 18-bits per revolution and speeds up to 10 000 rev/min. AksIM is a true-absolute encoder (no battery backup required) meaning that position is determined immediately at power-up, thanks to a unique single track code embedded in a corrosion resistant ring/

AksIM features an integral set-up and diagnostics LED, providing intuitive indication of signal health. The readhead also includes self-monitoring functionality, with the capability to report warnings, alarms or other status signals to the drive/controller via the communications interface.

AksIM is suitable for a diverse range of motion control applications, including robotics, pan-tilt/azimuth-elevation platforms, automation systems, and medical equipment.
