- Optical infrared technology enables precise, non-contact activation. In standby, the indicator is blue to help locate the switch position in low ambient light. When infrared sensing occurs, the backlight turns red and the door opens. - High quality stainless steel plate material provides firmness, corrosion resistance, and long-term durability. - Non-contact output makes this infrared switch suitable for a wide range of access control systems, reducing wear and improving hygiene. - Easy to install with minimal tools required; simple to wire and mount for convenient use. - Use scenarios - Office or commercial building access control: control entry to offices, labs, or restricted areas with reliable, non-contact switching. - Residential or hotel corridor entry: secure room or doorway access with durable, low-maintenance hardware. - Industrial or warehouse restricted areas: manage access to storage rooms or machinery areas where contactless operation is beneficial.
