KJT-SNG-SPRF-002-LY Speed Sensors

KJT's SNG-S Series Speed Sensors use a magnetically biased Hall-effect integrated circuit (IC) to accurately sense movement of ferrous metal targets. The specially designed IC and a permanent magnet are sealed in rugged, probetype packages. The IC detects the alteration of the magnet's flux density when it is approached by ferrous metal.
