LS 43-44
Light sensors
Alternating light sensors of the LS43/44 series are used in strip guiding systems for non-contact sensing of the strip edges.The strip material must be impervious to light. Alternating light sensors are designed as photoelectric edge sensors with largedistance coverage between the light emitter and the measuring receiver. The alternating light largely eliminates the influence of d.c. light and thereby ambient light. LS43 is used as measuring receiver, LS44 as reference receiver.
