Non-Oriented Hall Effect Sensors - HN Series
The HN series of speed sensors is based on Hall Effect sensor technology, which can sense a change in target motion from true zero to 20 KHz. These sensors incorporate a magnet within the sensor, enabling them to sense ferrous metal as well as magnetic targets. Maximum air gap sensing distances are typically 0.100".
MSI Hall Effect Sensors are optimized to provide extremely accurate tooth edge detection when used with larger pitch targets, and offer the unique advantage of not requiring orientation to the target. HN speed sensors integrate a preamplifier/signal conditioner within the sensor housing that provides excellent noise immunity and greater transmission capability.
They also have a unique circuit design that offers complete protection in the event of connection mis-wiring, not only reverse polarity. The output frequency of these sensors has a square pulse waveform (digital) that directly relates to the number of turbine blades, gear teeth, etc. that have been sensed. These pulses, in turn, can be correlated to determine flow rate, RPM, or velocity.
