Description
The metal port option for the
HFBR-0400 Series gives
designers the ability to have a
metal connector receptacle with
the familiar HFBR-0400 dual in-
line package (DIP). The metal
port option components have an
internal electrical connection
between the metal port and the
four grounding pins, as shown in
the package outline drawing.
Signal ground is separate from
the four grounding pins to give
the flexibility in connecting the
port to signal or chassis ground.

Styled Ports
This feature aids in maintaining
the integrity of the signal ground
if the chassis is exposed to elec-
trical noise. In addition, when the
metal port is in good electrical
contact with a well-grounded
chassis, the metal port provides
additional EMI shielding from
electrically noisy circuits.
Applications
HP recommends that the designer
use separate ground paths for the
signal ground and the conductive
metal port ground in order to
minimize the effects of external
coupled noise on receiver
circuitry. If noise is present on
the system chassis, care should
be taken to electrically isolate the
metal port from the chassis.
In the case of ESD, the metal port
option does not alleviate the need
for system recovery procedures.
A 15 kV ESD event entering
through the connector port will
not cause catastrophic failure,
but the metal port does not
guarantee error-free performance
during an ESD event.
Option M
The Metal Port Option is available
with SMA, ST, Threaded ST
(panel mount) and FC styled port
transmitters and receivers. The
electrical/optical specifications,
the mechanical dimensions, and
the pinouts of the components
with metal ports are identical to
the standard plastic port
products.
