Product Advantages
Discreet Infrared Emission
Standard 940nm infrared wavelength with almost no visible red light when powered, ideal for security cameras and concealed sensing applications.
Flexible Long-Lead Design
Extra-long straight leads can be freely trimmed according to PCB spacing, making them suitable for double-layer boards and long-distance solder pads.
High Batch Consistency
Strict chip sorting and wavelength control ensure minimal brightness and wavelength variation, helping sensing and recognition systems operate accurately.
Durable Clear Epoxy Body
Anti-yellowing transparent epoxy maintains stable light transmission in high and low temperature environments, supporting long-term indoor and outdoor use.
Efficient Infrared Output
Imported infrared chips deliver higher radiant intensity under the same current, helping devices achieve longer sensing distance with lower power consumption.
