Description
This general-purpose Photo Gate Sensor is commonly used to measure the time it takes for an object to pass between its arms. It is used for a wide variety of experiments in Physics and physical science classes.
Common usage
Measuring acceleration due to gravity
Studying the swing of a pendulum
Measuring the speed of a rolling object
Measuring the speed of objects undergoing collisions
Specifications
Range: 0 to 5 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 800 nm
