Product information "Hall Effect Gear Tooth Sensor IC CYGTS9803, Output: Dual-Channel Outputs, Power Supply: 4-30VDC"

The CYGTS9803 is a dual-channel gear tooth sensor, with two Hall sensing elements, each providing a separate digital output, for speed and direction signal processing capability. The sensor does not have a chopper delay and uses two Hall plates which are immune to rotary alignment problems. The bias magnet can be from 1000GS to 4000Gs. As the signal is sampled, the logic recognizes an increasing or decreasing flux density. The dual-channel outputs (OUTA and OUTB) are provided in the sensor. The OUTA will turn on (BOP) after the flux has reached its peak and decreased by an amount equal to the hysteresis. Similarly the OUTA will turn off (BRP) after the flux has reached its minimum value and increased by an amount equal to the hysteresis. The OUTB have the same function as OUTA. But due to the flux phase sequencing, the OUTA and OUTB have phase shift, which can be used to determine gear rotation direction.
