About This Product
The gate acts as a remote switch in a wide range of dynamics experiments. With the gate switched on, the two output sockets are short-circuited; each time an object interrupts the light beam the circuit opens, giving a connected electronic timer a clear signal.
Frequently Asked Questions
Q1. How does the light gate signal a timer?
When switched on it creates a short circuit between the two output sockets, which becomes an open circuit each time the light beam is interrupted.
Q2. How is the light source powered?
The light source housing has its own battery compartment and an on/off switch.
