PRECAUTIONS WHEN USING THE UVTRON
(1) Installation
When the UVTRON discharges, it emits ultraviolet radiation. If two or more UVTRONs are used in close
proximity, they must be arranged so that they will not interfere with each other optically.
(2) Humidity
Humidity around the UVTRON leads may cause leak current, dropping the anode voltage and stopping the
UVTRON from operating. In particular, if dirt or dust gets on the leads, it easily absorbs moisture, so keep the area
around the leads clean.
(3) Dirt on the window
Since the UVTRON operates at high voltage, static electricity causes dust to build up on the surface of the glass
bulb. This will lower the ultraviolet transmittance and UVTRON sensitivity, so periodic inspection and mainte-
nance is necessary, such as wiping off with gauze moistened with alcohol.
(4) Soldering
When mounting the UVTRON on a printed circuit board, solder the leads quickly (soldering iron tip temperature:
350°C for less than 5 seconds). If the leads are heated excessively, the glass may crack or the UVTRON
characteristics deteriorate. After soldering, wipe away the solder flux with alcohol, etc. The flux residue absorbs
moisture which may cause current leak, dropping the UVTRON supply voltage and stopping the operation. When
using a UVTRON with hard pins, use the mating sockets available from Hamamatsu Photonics.
(5) Vibration and shock
The UVTRON is designed to pass vibration and shock tests in compliance with IEC 60068-2-6 (sinusoidal
vibration test – R9454, R9533: 3.0 mm peak to peak, 200 m/s
2
,10 Hz to 2000 Hz; other types: 1.5 mm peak to
peak, 100 m/s
2
, 10 to 500 Hz) and IEC 60068-2-27 (shock test - R9454, R9533: 10000 m/s
2
, 1 ms; other types:
1000 m/s
2
, 11 ms). However, if the UVTRON is subjected to excessive shock such as dropping, the glass bulb may
crack or the internal electrode may be deformed, resulting in poor electrical characteristics. So use extreme caution
when handling the UVTRON.
(6) Polarity
The UVTRON has a cathode and an anode, so connect them with correct polarity. Reverse polarity connection
causes malfunction or breakdown.
