FLAME SENSOR UVTRON ®
R9454, R9533
Quick Detection of Flame from Distance,
Compact UV Sensor with High Sensitivity and Wide Directivity,
Suitable for Flame Detectors and Fire Alarms.
The UVTRON R9533 and R9454 are ultraviolet ON/OFF sensors that
utilize the photoelectric effect from metal and gas multiplication. These
devices are sensitive only to UV light in a spectral range of 185 nm to
260 nm. This makes them easy to use since they do not require optical
visible-cut filters. Their electrodes are optimized for ruggedness to resist
mechanical shocks up to 10 times (10000 m/s2) greater than the conventional UVTRONs.
The R9533 is a head-on type (UV light enters through the top of the bulb)
that easily installs into equipment. The R9454 is a side-on type (UV light
enters through the side of the bulb) whose outer appearance resembles
the conventional flame sensor R2868. Both these types utilize a plate
cathode and feature high sensitivity and a wide field of view (directivity).
APPLICATIONS
● Flame detectors for gas / oil lighters and matches
● Fire alarms
● Arson watch monitors
● Combustion monitors for burners
● Inspection of ultraviolet leakage
● Detection of discharge
● Ultraviolet switching

NOTE: 1This is the maximum momentary current that can be handled if its full width at half maximum is less than 10 µs.
2If the tube is operated near this or higher, the service life is noticeably reduced. Use the tube within the recommended current values.
3Measured under room illuminations (approximately 500 lux) and recommended operating conditions. Note that these values may increase if the
following environmental factors are present.
1. Mercury lamps, sterilization lamps, or halogen lamps are located nearby. 2. Direct or reflected sunlight is incident on the tube.
3. Electrical sparks such as welding sparks are present. 4. Radiation sources are present. 5. High electric field (including static field) generates across the tube.
4These are representative values for a wavelength of 200 nm and a light input of 10 pW/cm2. In actual use, the sensitivity will vary with the wavelength
of the ultraviolet radiation and the drive circuitry employed.

■ PRECAUTIONS FOR USE
● Ultraviolet Radiation
The UVTRON itself emits ultraviolet radiation in operation. When using two or more UVTRONs at the same time in close
position, care should be taken so that they do not optically interfere with each other.
● Vibration and Shock
These UVTRONs passed IEC 60068-2-6 (vibration test 3.0 mm peak to peak, 200 m/s2, 10 Hz to 2000 Hz) and IEC
60068-2-27 (impact test 10000 m/s2, 1 ms). However, if subjected to strong mechanical shocks such as drop impacts in
excess of the guaranteed values, the bulb may crack or internal electrodes may deform resulting in poor electrical
characteristics. So use extreme care when handling the UVTRON.
● Polarity
Connect the UVTRON at the correct polarity. Reverse polarity connection will cause malfunction or breakdown.
■ WARRANTY
The UVTRON is covered by a warranty for a period of one year after delivery. The warranty is limited to replacement of
any defective tube due to defects traceable to the manufacturer.

UVTRON® DRIVING CIRCUIT C10423, C10807 (Sold Separately)
The C10423, C10807 are compact drive circuits.
Since the high-voltage power supply and signal processing circuit are mounted on the same printed circuit board,
the C10423 operates as a flame sensor by just supplying
a DC voltage (12 V to 24 V) and connecting an UVTRON®. Please use C10423 with R9454, C10807 with
R9533. Please note that the R9533 lead pins cannot be
soldered directly to the C10807. A dedicated socket
(E678-8F) must be used to make the connection.
For more details, refer to the driving circuit catalog.
