Photogate Sensor

This general-purpose sensor is commonly used for a wide variety
of experiments such as studying the swing of a pendulum,
measuring the speed of a rolling object or measuring the speed of colliding objects.



Covered topics:


  • Range: 0 to 3 V
  • Detector rise time: 180 ns
  • Detector fall time: 180 ns
  • Parallax error: For an object passing within 1 cm of the detector, with a velocity less than 10 m/s, the difference between the true and effective length is less than 1 mm Infrared source: Peak at 875 nm
