Integrated A/D converter and digital signal processing with dynamically adaptive switch point improves accuracy and operation. Advanced circuitry protects the system from stray electro-magnetic fields and power spikes. Custom magnetic circuit programming calibrates the sensor during performance testing, which improves timing accuracy between target wheel and sensor output. Undergoes 100% environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude, which results in consistent product reliability. As a global manufacturer, we maintain complete quality control throughout the manufacturing process.
