Photoelectric barrier of 100 meters four light beams with Sniper viewfinder



The infrared transmitter and receiver must be perfectly aligned for optimal operation of the photoelectric detector. However, a lot of patience is required, time and effort to ensure that the receiver receives the maximum amount of infrared signal possible from the transmitter. Optex has the solution: the SL series is designed to lighten your workload and achieve perfect alignment.
