Hall Effect Gear Tooth Sensor

Hall Effect Gear Tooth Sensor

2-3 Days Del.

Quick Overview

1GT1 Series Tooth Sensors use a magnetically biased Hall effect integrated circuit to accurately sense movement of ferrous metal targets. This specially designed I.C., with discrete capacitor and bias magnet, is sealed in a probe type package for physical protection and cost effective installation. Output is digital, current sinking (open Collector). Reverse polarity protection is standard. If power is inadvertently wired backwards, the sensor will not be damaged.

Features

  • Senses ferrous metal targets
  • Digital current sinking output (open collector)
  • Better signal-to-noise ratio than variable reluctance sensors, excellent low speed performance, output amplitude not dependent on RPM
  • Sensor electronically self-adjusts to slight variations in runout and variations in temperature, simplifying installation and maintenance
  • Fast operating speed - over 100 kHz
  • EMI resistant
  • Reverse polarity protection and transient protection (integrated into Hall I.C.)
  • Wide continuous operating temperature range
