OSY5RU6EE2A is a part manufactured by Optosupply, a leading supplier of optoelectronics components and modules. It is an industrial grade, miniature single-channel, Hall-effect magnetic field sensor IC that measures and detects the vector component of an external magnetic field strength. This sensor is designed to respond to a magnetic field of 5-in-1 (X, Y, Z, H, and V) with an analog output that is either proportional to the detected field’s vector component, or reads the ambient temperature. Additionally, the sensing element is fully packaged with a castellated standoff, allowing for easy surface-mount assembly.
