Renishaw’s new AM4096 On-Axis™ magnetic encoder provides 4,096-counts/rev of absolute position feedback for high-speed digital motor and motion control applications. A non-contact 12-bit IC with no moving parts and programmable zero position, it delivers accuracy of 0.1°, at speeds up to 60,000 rpm – ideal for commutation, high-speed motor control, position/velocity control, and replacement of potentiometers and optical encoders.
The AM4096 is a low-power 3.3 V (or 5 V) device, and has a sleep mode for battery operation. It provides UVW outputs with 16 poles (eight pole pairs), and incremental, absolute, linear (potentiometer), Tacho generator and sinusoidal outputs. It can be supplied pre-programmed or can be customer programmed with settings stored in its on-chip EEPROM.
Designed and manufactured by Renishaw associate company RLS, the AM4096 consists of a simple magnet and IC, providing an ultra-compact, wear-free design, capable of withstanding temperatures from −40°C to 125°C. All sensor and processing electronics are within the compact silicon design. The rotation of a north/south magnet is picked up by the AM4096’s sensor and provides absolute positional information output.
