VR Sensor Conditioner (Single Channel)
Description:
Extract clean digital data from Variable Reluctance (VR) sensors with precision. This single-channel conditioner uses the MAX9924, the industry-standard IC for automotive-grade signal processing. Unlike basic detectors, the MAX9924 features an adaptive peak threshold, allowing it to reliably detect signals at low cranking speeds while remaining immune to high-frequency noise at high RPMs.
This is the definitive solution for any system using a VR/Magnetic pickup sensor that suffers from sync loss or timing drift.
-
Adaptive Performance: Automatically adjusts its internal threshold to match the sensor's voltage output.
-
High Noise Rejection: Differential input and precision zero-crossing detection eliminate false triggers from EMI.
-
Robust Connection: Uses a Molex 5557R-2*3P (Mini-Fit Jr.) connector for a secure, locking interface that stands up to vibration and harsh environments.
-
Universal Output: Delivers a clean square wave compatible with any digital input on an ECU, data logger, or microcontroller.
