Wheel Speed Sensor
Description
The "hall effect" wheel speed sensor is highly robust and designed specifically for high reliability automotive applications. It does not require a magnet to trigger it, just a moving metal "target", for example a bolt on the back of the brake disk. For direct connection to the DL1 a "pull up resistor" is required. If the sensor is ordered with a cable, this resistor is already included and will be ready for immediate use with the DL1.
Features
- Better signal to noise ratio than variable reluctance sensors.
- Sensor electronically self adjusts to slight variations in runout and variations in temperature.
- Fast operating speed – over 100 kHz
- EMI resistant
- Wide continuous operating temperature range.
