Compatible with 3V and 5V systems Instructions: Designed for PTZ encoders and encoder motors AS5048A rotation sensor 14-bit rotary position sensor with digital angle interface and pulse width modulation output The AS5048A is a 14-bit rotary position sensor for absolute angle measurement, featuring PWM (Pulse Width Modulation) output for full 360° rotation, based on non-contact magnetic sensing technology. Suitable for shaft applications using a two-pole magnet positioned above or below the sensor IC. Zero position can be programmed via simple SPI commands. Provides 14-bit absolute angular resolution (16,384 steps per revolution) with a serial SPI interface delivering digital position data. The AS5048 offers PWM output and supports SPI or I2C communication interfaces to deliver precise absolute angle measurements to microcontrollers. Eliminates the need for precise mechanical alignment between the chip and magnet during design. Zero position can be programmed using standard SPI or I2C commands during assembly without requiring special equipment, utilizing internal memory of the AS5048. Offers excellent tolerance to mechanical misalignment, air gap variations, and operates reliably across a wide temperature range. Delivers improved measurement accuracy compared to previous magnetic rotary encoders. The 14-bit analog front end enables a resolution down to 0.0219 degrees. With microcontroller processing for linearization and averaging, angular accuracy can reach 0.05 degrees. Package Includes 1 x AS5048A Magnetic Encoder
