Product Overview:

The PBY series is a digital triplicate-beam photoelectric detector developed for long-range outdoor perimeter intrusion detection.

By requiring simultaneous interruption of three infrared beams, the system enhances stability and reduces false alarms caused by environmental interference. Integrated 8-channel frequency selection and LED-assisted alignment allow reliable multi-unit installation.

The series supports professional alarm system integration and is available for standard supply programs as well as volume-based OEM customization projects.
