WebMay 6, 2016 · Optical switches, which use transistors to detect when an obstacle ("flag") is blocking the window between the emitter and sensor Hall effect switches, which use transistors to detect when a magnetic field exceeds a particular field strength cutoff Mechanical Switches WebThe non-contact or contact-less optical tachometers usually use laser or Infrared beam to monitor the rotation of any body. This is done by calculating time taken for one rotation. FEATURES It can measure RPM over 20k Sensor range extends upto 7~8 cm Displays Maximum RPM when left Idle Automatically toggles modes from "Idle" to "reading"
