Double Photocell
HL 2-32

Double photocell for a maximum reliablility

This photocell system uses two physically separate but electronically synchronized photocell transmitters and two independent receivers that are placed on opposite sides of the timing line. 
  
If necessary, each pair (transmitter/receiver) can be used separately in different timing locations. 
  
Timing line width up to 40 meters in "LOW" power position and up to 80 meters in "HIGH" power position. 
  
The receivers feature the use of a special additional lens that helps in the precise alignment of the cells from the opposite side of the timing line.
