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.

Product Specifications

In addition to the models specified, MSI can make Custom Hall Effect Sensors  in other lengths, diameters, configurations, mounting threads (e.g., metric) as well as with different operating specifications and options like pigtail leads, NPT threads for explosion proof applications, etc. to satisfy special requirements. In addition, for lower cost, high volume applications, MSI manufactures Hall Effect sensors that contain only the Hall Effect element, without special circuitry to guard against incorrect hook-up. These sensors are available with an open collector output and contain reverse polarity protection. If you do not see a sensor that meets your needs, please contact us and we would be happy to make a product that meets your specifications.
