Subminiature IP 67-rated Series W 2 uses metal-reinforced mounting holes and optical ASICs. Pinpoint LED''s laser-like light spot detects very small parts. Background suppression (0.6 and 1.2 in. range) reduces interference caused by moving or reflective objects. Features include photoelectric switch with 39.4 in. range; reflex systems for detection distance up to 31.5 in.; and energetic sensors with 2 in. range.
