- Interfaces: SENT, SPI, IO-Link, CANopen, CAN SAE J1939 and 5V ratiometric
- Resolution up to 16 bits per revolution
- Frontend: Enabling Security Device (ASIL-B)
Properties
| Feature | Specification |
|---|---|
| Features of the current prototype | |
| Mechanical coupling | Plug-in hollow shaft: the customer's D-shaft is inserted into the sensor actuator |
| Interface | CANopen |
| Supply voltage Ub | 8 … 32 VDC |
| Electrical connection | Molex connector with counter-connector and free wires |
| System | Open: IP protection depends on application integration |
| Magnetic shielding | To be done within the application: external magnetic fields can influence the sensor's performance |
| Measurement range and out-of-range behavior | |
| Operating range | 44 laps |
| Overrun at less than -1 lap or more than 45 laps | The sensor emits an additional error message |
| Error deleted | After returning to the measurement range, using «Position error reset» or by turning the device off and on. |
| Turn required to return to the measurement range | At least 3 turns in the opposite direction |
| Position signal after returning | It may NOT match the previous one: after an overtravel of more than 1 lap, the sensor emits a new, shifted exit curve. |
