Overview Non-contact Magnetic Angle Sensor — 360° · 14 bit · CAN J1939
A dual-channel non-contact magnetic sensor measuring the absolute angle of a rotating shaft. Non-contact sensing means no wearing parts; the full 360° range is resolved at 14 bit (0.022°), and angle values are transmitted together with diagnostics over CAN (J1939). IP69K sealing, a −40 to +125 °C operating range and DC 5–32 V supply keep it performing where vibration, shock and moisture are constant. In series production for Volvo CE excavators — a field-proven platform.
- Dual-channel cross-check — the two channels are continuously compared to detect anomalies
- Error history storage — up to 100 error codes with accumulated operating hours stored in NVSRAM, retained through power-off and retrievable over CAN
- Double O-ring sealing — seals the air gap between sensor and magnet bolt against moisture and contaminants
- Customizable to specification — measuring range, communication and mounting adapted to your system (see customization below)
