These sensors measure rotation speed with high sensitivity
The new SS360NT/SS360ST/SS460S High Sensitivity Bipolar Latching Digital Hall-effect Sensor Integrated Circuits utilize bipolar latching magnetics which make these products perfect for accurate speed sensing and revolutions-per-minute (RPM) measurement. These new sensors offer reliable switching points with high magnetic sensitivity of 30 G typical (55 G maximum) without using chopper stabilization on the Hall element, resulting in a clean output signal and the fastest latch response time in its class, the company says. Industrial and commercial applications include brushless d.c. motor commutation, flowrate sensing for appliances, speed and RPM sensing, tachometer pickup, motor and fan control and robotics control. — Honeywell Corp., Morristown, N.J.
