Product Code : SCL-PLE-10386
The Fork Light Barrier from Lab Glassware Manufacturer, based in Ambala, Haryana, India, is a physics laboratory optical timing sensor used to detect when an object interrupts a light beam during motion, velocity, acceleration, pendulum and trolley experiments. Lab Glassware Manufacturer has manufactured and exported physics lab equipment since 1982 to schools, colleges and training centres across countries including Serbia, North Macedonia, and Albania in the Southern Balkans region.
Quick answer: A fork light barrier is an optical timing gate that detects when a moving object (trolley, pendulum bob, falling mass) passes through its fork-shaped slot, generating precise start/stop timing signals for motion and dynamics experiments.

How Does a Fork Light Barrier Work?
An infrared or visible light beam runs across the gap of the fork. When an object such as a trolley flag, pendulum bob, or falling card breaks the beam, the sensor sends a timing signal to a connected counter/timer or data-logging interface, allowing precise measurement of velocity and acceleration in motion experiments.
Frequently Asked Questions
Q: What is a fork light barrier used for?
A: It detects the moment an object interrupts its light beam, generating precise timing signals for motion, velocity, acceleration, and pendulum experiments.
Q: What equipment does it connect to?
A: It is typically wired to a digital timer/counter or data-logging interface; confirm the connector/output type needed for your existing timer before ordering.
Q: Can it be used with a dynamics trolley?
A: Yes, it is commonly mounted along a roadway/track to time a trolley or smart cart as it passes through the beam.
Q: Does Lab Glassware Manufacturer export this internationally?
A: Yes, we manufacture and export physics lab equipment from Ambala, Haryana, India to schools, colleges and distributors worldwide.
