TPG. Transistor Photogate Trigger Kit, Unassembled
This kit includes parts for a photogate that uses a transistor to discharge a flash unit. The circuit can trigger on rapidly-moving objects. The matched infrared emitter and detector have separate housings. This allows the two parts to be placed different distances apart, depending on the application.
The kit also includes i) 3 feet of 2-conductor cable to connect the output to a flash unit and ii) 3 feet of 3-conductor cable to move the emitter-detector pair to a location away from the breadboard. |

An electronic delay unit is commonly used with the photogate to achieve timing synchronization. You receive a $1.00 discount when purchasing a TPG trigger with a delay unit. To order this combination, go to this page.
When purchasing a TPG kit with a breadboard, there's a $1.00 savings over buying a kit and breadboard separately.
