Miniature Photoelectric switches applicable to hose down requirements. There is a great variety of them, they ignore the background by adjusting the detection distance and only objects are detected.
IDEC miniatute photoelectric switches SA1E-X detects transparent objects, features a long sensing range up to 2m.
The detector SA1J is as easy to use as a photoelectric switch, but in contrast to the photoelectric switch SA1J ensures sophisticated color sensing.
High power water sensors detect water in opaque containers. X-rays are no longer required for detecting soft drinks or hair care products. Laser Class 1 (safe under all conditions of normal use). Water Detector (photocell lens type).
