Photo Gate Sensor
DT137
The Photo Gate Sensor is a general-purpose photo gate that measures the time it takes for an object to pass between its arms. The Photo Gate sensor is used for a wide variety of experiments in physics and physical science classes and is supplied with a mounting rod.
Typical Experiments
• Measuring the free fall acceleration • Studying the swing of a pendulum • Measuring the speed of a rolling object • Measuring the speed of objects undergoing collisions
How it Works
The Photo Gate sensor has a narrow, infrared beam and fast response time, which provides very accurate signals for timing.
