Sport fotocells

Photocells (photocells) designed for time measurement systems in sports. A photocell is a sensor that sends and receives visible, infrared or laser light. It is modulated so that the receiver can precisely catch the moment when the light has been blocked.
The operating range of the photocell, i.e. the width of the track on which it is placed, is 0.5m to 7m (TS-F7 photocell) or 0.5 to 20m (TS-F20 photocell).
The standard response time is 1-2 ms, and the battery lasts a full day of measurements.
The photocell can be placed on the tripods supplied in the set, or permanently attached to the wall or post. The set also includes a charger with a charging indicator.
In some competitions, an alternative to the photocell may be starting the time measurement with a bang gun, judge's button, mushroom - they can be found in the category Starters
