Selection table for GMI MI-CB-1 magnetic sensor modules, covering DH, DM, DL, DS, and DJ variants.
GMI magnetic sensor modules integrate an MI sensor element and driver circuitry on a PCB, offering high‑sensitivity magnetic measurement in a compact, easy‑to‑install form. The modules are offered in four families—DH, DM, DL, and DS—with DH and DM recommended for bulk supply.
Each family includes several models with different measurement ranges, frequency bandwidths, and noise performance. The table lists key specifications such as range (±2 µT to ±300 µT), bandwidth (0.1 Hz‑10 kHz), sensitivity, and PCB dimensions, helping users select the appropriate module for their application. This manual is written in Chinese.
| Measurement range (MI-CB-1DH) | ±2 µT |
|---|---|
| Frequency band (MI-CB-1DH) | 0.1‑1 kHz |
| Noise (MI-CB-1DH) | ±3 nT @ 0.1‑1000 Hz |
| Measurement range (MI-CB-1DM) | ±300 µT |
| Frequency response (MI-CB-1DM) | DC‑10 kHz |
| Sensitivity (MI-CB-1DM) | 4 mV/µT |
| PCB size (MI-CB-1DL) | 31.5 mm × 11 mm |
| Measurement range (MI-CB-1DS) | ±8 µT |
| Frequency bandwidth (MI-CB-1DS) | 0.3 Hz‑5 Hz |
The MI‑CB‑1DH module measures magnetic fields up to ±2 µT.
The DH and DM models are recommended for large‑volume production.
The MI‑CB‑1DL module uses a PCB that is 31.5 mm by 11 mm.
