UV TRON UV Photodiode Sensor R2868 R9454 Used For Flame Detectors

UV TRON R2868 R9454 Used for flame detectors


The R9454 is a side window type (UV light enters from the side of the bulb) and is similar in shape to the R2868 UVtron, with high sensitivity and a wide field of view (directivity).


Spectral Sensitivity Characteristics (Short)185 nm
Spectral Sensitivity Characteristics (Long)260 nM
Discharge Sustain Voltage (DC)300 V
Background maximum10 min-1
[Recommended Operating Parameters] minimum quenching time2 ms
[Recommended Operating Parameters] average discharge current0.3mA



The R2868 is a UVTRON UV on/off detector that utilizes the photoelectric effect of metals and the multiplication effect of gases. It has a narrow spectral sensitivity of 185 nm to 260 nm and is completely insensitive to visible light. Unlike semiconductor detectors, it does not require a visible cut-off filter, making it very convenient to use.


Spectral Sensitivity Characteristics (Short)185 nm
