PRECAUTIONS FOR USING THE UV TRON
G
UV TRON light emission
When the UVtron discharges, it emits ultraviolet radiation. If a number of UVtron are used in close proximity, they must be
arranged so that they will not interfere with each other optically.
G
Humidity
Humidity around the leads for the UVtron generates leak current, dropping the anode voltage, and stopping the tube from
operating. In particular, if dirt, dust etc. get on the leads, that makes it easier for humidity to be absorbed, so keep the area
around the leads clean.
G
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
invites lowering of the ultraviolet transmissivity and sensitivity of the UVtron, so periodic maintenance, such as wiping off
with gauze dipped in alcohol, is necessary.
G
Soldering
For mounting the UVtron on a printed circuit board, solder it quickly (350
°
C for less than 5 seconds). If the leads are
heated excessively, the glass can crack or the characteristics of the UVtron deteriorate. After soldering, wipe away the
solder flux with alcohol or a similar agent. If the leads are left dirty, current leak due to humidity will lower the voltage
applied to the UVtron socket available from HAMAMATSU.
G
Vibration and shock
UVtrons have passed vibration and shock tests in compliance with JIS C 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 Hz to 500 Hz)
and JIS C 60068-2-27 (shock test - R9454, R9533: 10000 m/s
2
, 1 ms; other types: 1000 m/s
2
, 11 ms). However Cif
subjected to strong mechanical shocks such as drop impacts, the glass envelope may crack or internal electrodes may
deform resulting in poor electrical characteristics. So use extreme caution when handling the UVtron.
G
Polarity
Connect the UVtron with correct polarity. Reverse polarity connection will cause malfunction or breakdown.
I
WARRANTY
The UV TRON 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.
