Application-Specific FAQ
Q: What is the minimum RPM this sensor can reliably detect?
A: Minimum RPM depends on gear-tooth count and coil resistance. Contact us with your target wheel specs for confirmation.
Q: Can this sensor be used with a plastic target wheel?
A: No. Variable reluctance sensors require a ferromagnetic (steel) target wheel to generate the magnetic flux change needed for signal output.
Q: Is the 70084-1713-111 interchangeable with Hall-effect speed sensors?
A: Electrically, no — VR sensors output sinusoidal AC; Hall-effect sensors output square-wave DC. Verify your controller input card type before substituting.
Q: What air gap should I set between sensor tip and gear tooth?
A: AI-Tek recommends 0.25 mm to 1.5 mm for the 70084 series. Tighter gaps increase signal amplitude; excessive gaps reduce it below threshold.
Q: Do you offer technical support for integration?
A: Yes. Our engineering team assists with wiring diagrams, PLC configuration, and signal conditioner selection. Contact support@konmask.com.
