AS20-M42-010

AS20-M42-010 is an AS20 series miniature encoder. It is a magnetic sensing absolute multi-turn encoder kit based on Broadcom's proprietary energy harvesting (EH) technologies. The EH multi-turn (EHMT) offers battery-less and non-gear-based solutions, eliminating the need for maintenance and contamination prevention. The beauty of the EH effect is that the same amount of energy is generated independent of the rotation speed and direction. The generated energy is sufficient to power the revolution tracking circuitry. Hence, revolution counts are ensured even in the absence of an external power supply. It offers bundles of intelligent features such as a built-in temperature sensor, user-programmable resolution, zero reset, system alarm, and more. It is used in applications such as miniature servo motors and drives, linear actuators, medical and laboratory equipment, robotics, automated guided vehicles (AGV), and factory automation.
