Frequently Asked Questions

What does "passive" mean for this sensor?

Passive operation means the sensor generates its own signal without needing external power. It produces voltage through magnetic induction when gear teeth pass the sensing face.

What is the minimum detectable signal level?

The sensor guarantees 0.3V peak-to-peak output at the specified guarantee point, ensuring reliable detection even at lower speeds.

Can this sensor operate in high-temperature environments?

Yes, the sensor withstands temperatures up to 150°C, making it suitable for demanding industrial applications near engines or hot machinery.

What is the purpose of the specified inductance value?

The 2 mH inductance affects signal characteristics and cable length compatibility, ensuring proper signal transmission to monitoring equipment.

How should I connect the sensor leads?

Connect the white lead as positive to maintain correct signal polarity for accurate speed measurement and direction detection.
