| Frequency range | 0 Hz to 10 kHz |
| Installation gap (standard) | 0.8 mm |
| Output waveform | Square wave |
| Number of output channels | 2 |
| High‑level output voltage | VH ≥ Vcc − 2.5 V |
| Pulse duty cycle | 50 % ± 20 % |
| Phase difference | 90° ± 30° |

Adjust the gap to 0.8 mm as strongly recommended.
Power the sensor and bring a ferromagnetic piece close to or away from the sensor head; the output level will toggle high/low, indicating normal operation.
The sensor is likely damaged and should be replaced.
