Solid State Sensors Hall Effect Gear Tooth Sensors
FEATURES Senses ferrous metal targets Digital current sinking output (open collector) Better signal-to-noise ratio than variable reluctance sensors, excellent speed performance, output amplitude dependent Sensor electronically self-adjusts slight variations runout variations temperature, simplifying installation maintenance Fast operating speed over resistant Reverse polarity protection transient protection (integrated into Hall I.C.) Wide continuous operating temperature range 150°C), short term 160°C
Series
GENERAL INFORMATION 1GT1 Series Gear Tooth Sensors magnetically biased Hall effect integrated circuit accurately sense movement ferrous metal targets. This specially designed I.C., with discrete capacitor bias magnet, sealed probe type package physical protection cost effective installation. Units will function from power supply. Output digital, current sinking (open collector). Reverse polarity protection standard. power inadvertently wired backwards, sensor will damaged. Built-in protection against pulsed transients +60V, -40V also included. Optimum sensor performance dependent following variables which must considered combination: Target material, geometry, speed Sensor/target Ambient temperature Magnetic material close proximity
