ams AS5261 双模(die)位置传感器

×

Description

The AS5261 is a redundant, contactless Hall-based magnetic position sensor for very accurate angular measurement over a full turn of 360°. It is a compact integrated solution which provides the absolute angle measurement with a resolution of 0.09° over a full revolution as PWM output signal. The internal 14-bit core of the AS5261 enables a fine programming of the start and stop positions with a resolution of 0.02° to allow the finest system mechanical adjustments.

With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.
