Encoders are essential components of electrical systems. They provide angular positions, speeds, and distances measurements for motion control and automation systems. The AS5145B-HSSM is a high-performance magnetic rotary encoder that uses Hall sensors to detect the angular displacement of a shaft within its mechanical limits. It is typically used in applications such as safety, measurement, and control systems, which require a high level of precision in both the range and resolution of the motion.

The AS5145B-HSSM is a compact, low power, high accuracy encoder that provides accurate resolution and linear displacement. It utilizes Hall sensors, which are sensitive to the magnetic fields generated by a moving encoder, and sends command signals to the host CPU corresponding to changes in the field. The scale resolution is 0.292° (i.e., 12-bit resolution) and the information remains stable even while in motion. The encoder also features anti-interference and vibration resistance, which ensures reliable operation even in challenging environmental conditions. It also features a temperature range of -40°C to +105°C.

In addition to its accuracy and resolution, the AS5145B-HSSM provides the flexibility of multiple communication interfaces. It is available in both I²C and SSI versions, which support I²C write commands, and the programmable I²C I/O pin is used for further configuration. The SSI version also offers programmable reset and supply voltages, as well as a Serial Data Out pin for up to five bit selections.

Angular velocity is measured by the Hall sensors, which are monitored by the AS5145B-HSSM’s built-in algorithms. Angular velocity is calculated by counting the changes in magnetic field per unit time. The velocity is determined by the rate of change of the magnetic field’s amplitude and/or frequency. The algorithm compensates for the Doppler effect phenomena, which accounts for changes due to the relative movement of the rotating element and the encoder. The velocity is then used to calculate the angular position of the rotating element.

The AS5145B-HSSM is ideal for use in applications where precision is key, such as medical applications, automotive applications, building automation, robotics, and industrial control. Its small size, high accuracy, and wide temperature range make it an ideal choice for these applications.

As an encoder, the AS5145B-HSSM is designed to provide precise, accurate readings of angular positions of a rotating element. It works by using Hall sensors to detect the magnetic field generated by the motion of the encoder, and uses its algorithms to determine the angular velocity and calculate the angle position. It also offers the flexibility of multiple communication interfaces. Its small size, high accuracy, and wide temperature range make it well suited for use in a wide variety of applications.
