Smith Systems, Inc. passive speed
sensors convert mechanical motion to an A/C
voltage without the need of a power supply. These self-contained magnetic
sensors produce a magnetic field which, when in the proximity of ferrous objects in motion, generate a
voltage. The frequency of this
voltage is directly proportional to the speed of the object in motion. Magna-Tran ® speed
sensors are available in a variety of housing configurations and terminations. Housing configurations to accommodate high...
