20 Meter Infrared Beam Protection: This infrared photoelectric beam creates an invisible security barrier spanning up to 20 meters between transmitter and receiver, triggering an immediate alarm when the beam is interrupted by intruders.
Designed with 940nm wavelength technology and advanced circuitry, this photoelectric detector maintains stable operation in various conditions, though range may reduce by 30% during heavy fog, rain, or dust.
The complete photoelectric beam alarm system includes one transmitter and one receiver that install on opposite sides of doorways, window, or pathways, creating an effective security perimeter with DC 12V power requirement.
Suitable for both home security systems and commercial use, this infrared sensor detector provides reliable protection for schools, offices, parking areas, and residential properties with its 1A relay output for alarm connectivity.
Housed in hard plastic shells, these detectors operate effectively in temperatures from -10℃ to 70℃, ensuring year-round reliability for your property security needs.
