2-wire digital current output
• Wide speed capability • One pulse per
pole pair output and differential bridge
operation • Output pattern independent
of gap between target and sensor
• Improved insensitivity to run-out, tilt
and twist • Enhanced sensitivity
• Reverse polarity protection • Miniature,
TO-92-style plastic package
High performance, digital, 2-wire, magnetoresistive sensor in a miniature, flat, TO-92-style plastic package with a current output designed for sensing fine pitch ring magnets. Wide speed capability provides application flexibility with true zero speed sensing and operation up to 3000 Hz. One pulse per pole pair output and differential bridge operation allow compatibility with differential Hall sensors, making it easier to upgrade existing applications.
Enhanced sensitivity, ±7 Gauss typical allows for larger air gaps (up to 2,5 mm [0.098 in]) and higher pole density (up to 50-pole pairs depending on ring diameter). Patented bridge array optimized to allow a greater air gap between the target and the sensor with reduced loss in sensor signal or accuracy. Potential applications include wheel speed sensing and shaft speed encoding using a multipole ring magnet in a wide variety of off road transportation, industrial and medical equipment.
