This document describes the features and characteristics of SENSOR PRODUCTS' 1-axis and 2-axis magnetic sensors HMC1001 / 1002 and HMC1021 / 1022, as well as their applications in compassing systems, attitude reference, traffic detection, and medical devices.
This document provides technical specifications and application information for Honeywell's HMC1001, HMC1002, HMC1021, and HMC1022 linear magnetic field sensors. These magnetoresistive (MR) sensors are designed for 1-axis and 2-axis sensing applications, including compassing, navigation, and traffic detection. The sensors feature on-chip coils and patented offset straps to reduce temperature drift and hard iron distortion effects.
| Bridge Supply Voltage | 5 to 12 Volts (HMC1001/1002) |
|---|---|
| Bridge Resistance | 600 to 1200 ohm |
| Operating Temperature | -55 to 150 °C |
| Field Range | ±2 gauss (HMC1001/1002) |
| Field Range | ±6 gauss (HMC1021/1022) |
| Noise Density | 29 nV/√Hz (HMC1001/1002) |
| Noise Density | 48 nV/√Hz (HMC1021/1022) |
| Bandwidth | 5 MHz |
They are used for compassing, navigation systems, attitude reference, traffic detection, and medical devices.
The sensors can withstand a maximum exposed field of 10,000 gauss without a perming effect on the zero reading.
The patented on-chip set/reset straps reduce temperature drift and non-linearity errors, while offset straps eliminate hard iron distortion effects.
