WebOther popular technologies for smoke detectors are ionization alarms and dual sensor smoke detectors. A dual sensor smoke alarm has both ionization and photoelectric sensors inside. Ionization smoke alarms are best for detecting rapid flame fires, while photoelectric smoke alarms are best at protecting against slower, smoldering fires. WebPhotoelectric sensors (also known as photo eyes) allow non-contact detection of objects using red or infrared guided light. IP69K sensors are rated for harsh duty (food grade/ washdown) applications. Standard, compact, and miniature rectangular models. 4mm, 5mm, 8mm, 12mm, 18mm, and 30mm round.
