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.

40-670 Very High Density Multiplexer Range:

1 Bank, 198 Channels, 1-Pole

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connector that has been superseded by a Pickering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.
