4m Reflective Infrared Photocell Photo Eye Beam for Garage Sliding/Swing Gates & Door Openers

Important note: the '2M' printed on the box indicates the sensor cable length only and is not the detection range; the manual's '4m' value is outdated and incorrect. This is a retro-reflective infrared photoelectric sensor intended for gate openers, boom barriers, sliding/swing gates and door openers. Power options are offered in both 110V/220V AC and 12V/24V DC versions. Light source: Infrared LED. Built to withstand impacts and vibration with strong anti-shock and anti-vibration construction. Non-contact detection prevents the sensor from physically touching targets, protecting the sensing element and extending service life. It senses objects by measuring reflected light, so it can detect a wide variety of materials including glass, metal, plastic, wood and fluids. Fast response time — up to 3 ms. The sensor can also distinguish object color based on differences in reflectivity and absorptivity. High precision electronics ensure accurate positioning and the ability to detect very small targets.
