4m Reflective Infrared Photocell Photo-Eye Beam for Garage Sliding & Swing Gates, Doors — Retro-Reflective Sensor with Smart WiFi Control

Retro-reflective infrared photo-eye designed for gate openers and boom barriers — suitable for garage sliding and swing gates and door openers. Available in two power variants: 110V/220V (AC) and 12V/24VDC (DC). Important packaging/manual note: the "2M" printed on the box indicates the sensor cable length, not the detection distance. The manual’s claim of "4m" detection is outdated and not correct; the documentation was not updated.
