The 40-670 series of very high density multiplexer modules
feature a wide range of switching configurations. Typical
applications include signal routing in ATE and data
acquisition systems.
The module is factory set into one of the multiplexer
configurations shown in the table below (also refer to
schematics overleaf). Connections are made via a front
panel 200-pin connector.

1 Bank, 10 Channels, 8-Pole, Screened
1 Bank, 5 Channels, 16-Pole, Screened
The majority of 40-670 models (see order codes) allow
multiple channels to be simultaneously selected.
Alternatively, product variants can be supplied that operate
as a conventional multiplexer with break-before-make
action when a new channel is selected.
Note: The multiple channel selection option is not available
for the 40-670-022-198/1 multiplexer.
Built in automatic isolation switching (available in 1, 2
and 4-pole mode, see diagrams overleaf) connects only
the currently active multiplexer bank on to the analogue
common, keeping capacitive loading and leakage current
in large multiplexer systems to a minimum. Larger
multiplexers may be constructed by daisy chaining the
common signals from multiple modules.
The screened version (40-670-021-S) is suitable for
applications where improved noise performance is
required.
Relay Type
The 40-670 is fitted with ruthenium sputtered reed relays,
these offer very long life with good low level switching
performance and excellent contact resistance stability.
Spare reed relays are built onto the circuit board to allow
easy maintenance with minimum downtime.
All reed relays are manufactured by our Relay Division:

Front Panel Connector
This product is based on the obsolete Molex LFH series
connector that has been superseded by a Pickering
commissioned form, fit, function equivalent. The new
connector series is 100% compatible with the Molex
connectors allowing either gender of Pickering connector
to mate with the corresponding Molex part without issue.
