VCE3766 Dual-track Off-Axis Magnetic Encoder for Mechanical Joint Applications 可替代IC-mu150

VCE3766 and VCE3768 are vernier magnetic encoders
based on Anisotropic Magnetoresistance (AMR)
technology. It scans two independent magnetic tracks to
determine the absolute rotational position within a single
turn and provide corresponding outputs. The devices
delivers an angular output with up to 21-bit effective
resolution and an accuracy (INL) of 0.02°. It supports
magnetic field detection at speeds up to 32,000rpm at
pole pairs are 32, making it particularly suited for
structures requiring off-axis installation.
Based on the inherent advantage of AMR technology in
saturation mode, which renders it insensitive to
magnetic field strength variations, the VCE3766 and
VCE3768 exhibits excellent vibration resistance and low
temperature drift. This makes it adaptable to a wide
range of harsh operating environments. Additionally, the
device provides multiple output interfaces, including SPI,
SSI, ABZ, UVW, and analog outputs, to accommodate
diverse applica
