Unsure what you mean by high density versus regular pins. Do you mean
HD
= triple row of pins like a laptop VGA connector? The Becker connector
is
a double row of 25 pins. I cannot tell if the connector linked by Ross
from Conrad.com has crimp type pins or solder type pins.

It is a bog-standard DB25 25-pin connector as used to be used for RS232 PC
connection.

The pin-out can be found in the Installation Manual

Tim,

As you said the d-sub connector (and shell) are about as common as dirt. But one way or another you need to securely attach the connector to the radio or risk things wiggling loose at an inopportune moment. Thus John Foster needing this Becker latch thingy.

The sliding latch arrangement used on Becker radios is not something I had seen prior to working with non-US avionics. FYI - Filser/Dittel radios have a yet another type of sliding latch arrangement.

What I commonly find on US equipment (and Australian Microaire radios) is that the connector shell has a captive screw which engages into the equipment's (radio's) matching threaded insert (called an "SAE 4-40 jack socket screw").

This "US" system is very (more?) secure but it is not as easy to engage in tight spaces as the simple "Euro" sliding latch. This "US" SAE 4-40 screw system will not work with Becker/Filser/Dittel radios unless their sliding latch system is replaced with a threaded insert (and the radio's hardware is metric).

Why hasn't the US gone metric? Hmmmmm.
