High Accuracy Differential Speed Sensor IC CYGTS9621 with Zero-Crossing Output Signal, Output Signal: Single NPN Voltage, Power: 3.8~24VDC

The differential Hall Effect Gear Tooth sensor CYGTS9621 provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. CYGTS9621 is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as anti-lock braking systems, transmissions, crankshafts, etc. The integrated circuit, which is based on Hall Effect principle, is response to changing differential magnetic fields created by rotating ring magnets and by ferrous targets when coupled with a magnet and provides a digital signal output with frequency proportional to the rotational speed. A differential Hall IC is not influenced by radial vibration within the effective airgap of the sensor and require no external signal processing.
