The HMC1501 / HMC1512 is Honeywell's high-resolution, low-power MR sensor capable of measuring the angle direction of a magnetic field from a magnet with <0.07° resolution. Advantages of measuring field direction versus field strength include: insensitivity to the tempco of the magnet, less sensitivity to shock and vibration, and the ability to withstand large variations in the gap between the sensor and magnet. These sensors may be operated on 3 volts with bandwidth response of 0-5 MHz. Output is typical Wheatstone bridge.
This document provides technical specifications and application information for the Honeywell HMC1501 and HMC1512 sensor products. These are high-resolution, low-power Magnetoresistance (MR) sensors capable of measuring the angle and direction of a magnetic field with high precision. The HMC1501 offers an angular range of +45 degrees, while the HMC1512 provides an angular range of +90 degrees.
