DESCRIPTION
These small and versatile digital Hall-effect devices are operated by the magnetic field from a permanent magnet or an electromagnet, and are designed to respond to alternating North and South poles. The built-in regulator provides enhanced stability of operation from 4.5 Vdc to 24 Vdc supply voltage range, and internal circuitry is designed to prevent sensor damage in case the supply voltage polarity is accidentally reversed. The open-collector sinking output voltage is easily interfaced with a wide variety of electronic circuits. 

FEATURES
• Small, leaded, flat TO-92-style package allows for a compact PCB layout
• Wide operating voltage range of 4.5 Vdc to 24 Vdc allows
   these sensors to be used in a variety of applications
• Current consumption of only 5 mA max. at 4.5 Vdc for
   energy efficiency
• Bipolar magnetics for ring magnet applications with
   alternating North and South poles
• Robust design: Will operate up to 150°C [302°F]
• RoHS-compliant materials meet Directive 2002/95/EC

POTENTIAL APPLICATIONS
• Industrial: Speed and RPM (revolutions per minute) sensing,
   tachometer, counter pickup, flow-rate sensing, brushless dc
   (direct current) motor commutation, motor and fan control,
   robotics control
• Transportation: Speed and RPM (revolutions per minute)
   sensing, tachometer, counter pickup, motor and fan control,
   electric window lift, convertible roof position
• Medical: Motor assemblies, medication dispensing control
