RLS3C-S Triple Photocell



The RLS3C-S Three Fold Photocell are mounted on top of each other and can be used up to 15m appart.  There are two different operational modes depending on the required use

Mode 1:

The three photocells will only send an impulse when all three cells are covered at the same time. Before another impulse is received each beam must be clear again. (e.g. for athletics)

Mode 2:

The three photocells work individualy, this means if you break one photocell beam you will get an impulse (e.g. for soccer ball speed, agility, horse races, etc.).

Used for:

Switch position

  • mode 1: Athletics Switch position
  • mode 2: Soccer ball speed, Agility, horse racing, etc.
