Product description
HCM600B/HCM605B is a dynamic 3‑axis electronic compass integrating a 3‑axis accelerometer, 3‑axis gyroscope and 3‑axis magnetometer. Roll, pitch and heading are computed in real time by a 32‑bit high‑speed processor. Available modes: pure compass, 9‑axis fusion and 9‑axis fusion anti‑jamming. Hard‑iron and soft‑iron calibration algorithms and inertial compensation maintain accurate heading even at large tilt angles (roll ±180°, pitch ±85°). The sensor is a slim strip (L111.5 × W19.5 × H19.5 mm) with low power consumption and can be supplied as a module or as a housed unit (up to IP67). It is intended for industrial attitude and heading measurement in applications such as antenna stabilization, vehicles and unmanned platforms.

Scope of application

• Engineering and construction vehicle leveling
• High‑altitude platform safety protection
• Shield/tube jacking and tunnelling applications
• Medical device angle control
• Underground drilling rig attitude navigation
• Orientation measurement based on inclination
• Geological equipment tilt monitoring
• Mining machinery and oil drilling equipment
• Equipment level control
• Alignment control and bending control
