Photocells - Polifemo

Fotocellule - Polifemo - Professional Timing | Microgate

The state-of-the-art photocell:

  • possibility of setting disactivation times;
  • double outputs insulated from each other;
  • selection of impulse type (start-stop-lap);
  • normal or monostable functioning;
  • selection of reflection functioning (range of over 35 metres) with facing transmission and reception photocells (range 90 metres);
  • low battery indicator;
  • embedded ‘smart’ recharge circuit;
  • possibility of substituting the rechargeable batteries with two AA batteries (over 15 hours of battery life)

Polifemo photocells can be fitted on request with the TDMF module for remote checking of the charge level and signal level. The values taken are sent using the same connection used for the signal.
