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printed on the box indicates the sensor cable length only and is not the detection range; the manual's '4m' value is outdated and incorrect.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.You may also like SL1500AC Automatic Sliding Gate Opener Motor for Max 1500kg Slide Gate — Optional Photocell, GSM Module & Keypad.
