描述 Description

The AS33-M42M series encoder is a?42-bit?absolute magnetic encoder comprising?18-bit single-turn (ST) and 24-bit multi-turn (MT) counts?by Broadcom Inc.The design of this?encoder features state-of-the-art Energy Harvesting Multi-turn technology.?This technology converts rotating magnetic field into electrical energy, which powers the revolution tracking circuit regardless?of the encoder rotation speed and direction.?Therefore, there is no loss of revolution count even in the absence of external power supply.?Energy Harvesting Multi-Turn?does not require periodic maintenance of the battery backup components and the downtime associated with it.To improve system integrity and simplicity, a single magnetic solution is responsible for both ST and MT positions generation.The AS33-M42M series encoder has a built-in communication protocol, which is supported by a full-duplex or half-duplex line transmissions drive, offering good noise immunity for more robust transmission of data in SSI/BiSS-C/RS485 protocol up to 10Mbps in harsh industrial applications. Being a magnetic technology-based encoder, it is a robust solution against contamination such as dust and fingerprints on the sensing element. As a result, it requires less stringent controls in production handling and harsh environments.Calibration Kit & Alignment Tools Ordering InformationAccuracy calibration is required to achieve the specified accuracy performance.?1.?
