Metal Package PMT with Cooler
H7422 Series option
TPMOC0145EC
● Heatsink with Fan A7423
The temperature of the H7422 outer case rises due to the ther-
moelectric cooler housed in the case. The A7423 heatsink effi-
ciently radiates away this heat to prevent a temperature rise in
the H7422. The A7423 can be easily installed onto the H7422
with four M3 screws. Apply a heat conductive grease onto the
joint surface shared by the H7422 and A7423.
● Signal Cable E1168-05
This signal cable is terminated with a BNC connector for easi-
ly connecting the H7422 to external equipment.
● Optical Fiber Adapter (FC Type) A7412
The A7412 is an FC type optical fiber connector that attaches
to the light input window of the H7422. The A7412 can easily
be secured in place with four M2 screws.
● C-Mount Adapter A7413
The A7413 mount adapter is used when a C-mount lens pro-
truding 4 mm or more from the flange-back must be installed
onto the H7422.

Power Supply Unit with Temperature Control C8137-02
The C8137-02 is a power supply unit with a temperature con-
trol function. Just connecting to an AC source of 100 V to 240
V generates the output voltages for the thermoelectric cooler
and the A7423 fan, needed for operating the H7422. The pho-
tomultiplier tube temperature can be maintained to 0 °C by
monitoring the thermistor and regulating the output current for
the thermoelectric cooler. Control voltage can be varied by a
knob on the front panel.

Power Supply Unit with Temperature Control M9012
The M9012 is an on-board type power supply unit.
By just connecting to 12 V supply, the M9012 provides power
necessary to operate the H7422 series. The M9012 also
controls the thermoelectric cooler in the H7422 series so that
the output and noise can be maintained at constant levels
even when the ambient temperature changes. The
thermoelectric cooler and PMT operation can be controlled
from an external device by connecting it to the I/O connector
on the M9012.
