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 maximum separation is about a foot (30 cm). If your application requires greater separations, a red laser pointer can be substituted for the infrared LED.
The kit includes 3 feet of 3-conductor cable to extend 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.
You can purchase this kit assembled.
