The R7400U series is a subminiature photomultiplier tube with a
16 mm diameter and 12 mm seated length. A precision engi-
neered 8-stage electron multiplier (composed of metal channel
dynodes) is incorporated in the TO-8 package to produce a noise
free gain of 700,000 times (R7400U). The R7400U series also
features excellent response time with a rise time of 0.78 ns. Vari-
ous types of the R7400U series are available with different spec-
tral response and gain ranges, including those selected specifi-
cally for photon counting applications. Hamamatsu also provides
a hemispherical lens input option to the series (R7401 and
R7402), effectively doubling the active area.
FEATURES
World's smallest photomultiplier tubes assembled in a TO-8 metal package (1/7th of the Hamamatsu R647).
The necessary components are built into a TO-8 package while retaining full photomultiplier tube performance to cre-
ate a new generation of photosensors.
Photon counting type: R7400P.
The R7400P is specially selected on account of low noise and high gain for use in photon counting applications.
Hemispherical lens window types: R7401 (bialkali), R7402 (multialkali).
The hemispherical lens window doubles the effective input area to 12 mm in diameter.

The E5770 and E5780 are compact socket assemblies incorporating a voltage divider circuit comprised of resistors
and capacitors. These socket assemblies are designed to provide the output signal directly from the anode of the
metal package photomultiplier tube.
* When the E5770 is used with the anode at a positive high voltage, the negative high voltage (-HV) terminal should be grounded
and a positive high voltage applied to the ground terminal. In this arrangement, a high voltage differential is generated between the
output and an external amplifier, so use a decoupling capacitor that can withstand a high voltage.
** In the E5780, the shield of the signal output cable is connected to the grounded cable, so the E5780 can be used only for negative
high voltage operation. Consult our sales office when the E5780 is needed for positive high voltage operation.

WARNING: HIGH VOLTAGE
The H6779/H6780 series are new light sensor mod-
ules including the compact photomultiplier tube,
(METAL PACKAGE PMT) and operating power
supply. It features low voltage operation (+15 V)
and low power consumption (Approx. 450 mW for
H6779/H6780). Compared with current light sen-
sors, it has several advantages like high sensitivity,
wide dynamic range and fast time response. These
are featured by the PMT and the Cockcroft-Walton
high voltage power supply. The H5773/H6779 ser-
ies are on-board types which facilitates mounting
directly on a printed circuit board and the
H5783/H6780 series have a cable output. H5784
series are cable out type with an amplifier of DC to
20 kHz bandwidth. These versions accept direct
light input or an optical fiber with the optional fiber
connector of E5776.

The metal package photomultiplier tubes are operated by applying a high voltage. Use extreme caution
to avoid electrical shock and damage to the peripheral equipment and be sure to provide adequate safety
measures as needed. As safety measures, an insulation cover is fitted to the metal package which is
electrically connected to the photocathode. When operated with the cathode at a high voltage (anode
ground scheme), the metal package will be at this same high voltage level. Removing the insulation
cover is extremely dangerous, so never attempt to remove it from the package.
