RLS AksIM-2 Off-Axis Rotary Absolute Magnetic Encoder
Vendor: RLS (Renishaw Group)
Product: AksIM-2™
RLS (Slovenia, part of the Renishaw group) is a specialist in rotary and linear magnetic encoders. AksIM-2 is a non-contact off-axis absolute rotary encoder module for applications with limited installation space: a compact, low-profile readhead detects the field of a thin axially magnetized ring. It uses a custom magnetic-sensor ASIC with BiSS C, SSI or asynchronous serial output, resolutions up to 20 bits, true absolute measurement with no hysteresis, built-in self-monitoring and a self-calibration option, and immunity to external magnetic fields; system accuracy after self-calibration is +/-0.004 to +/-0.020 deg (+/-14 to +/-72 arcsec), max speed 10,000 rpm, 4.5-5.5 V supply (typ. 130 mA); ring inner diameters span 8-68 mm in 11 sizes with -40 to +105 C operation. Used for position feedback in electric motors, medical devices and robot joints.
