40-670A-022 198-Channel 1-Pole Multiplexer
The 40-670A module features a wide range of multiplexer
configurations based on high performance ruthenium reed
relays. Typical applications include signal routing in ATE
and data acquisition systems. User connections are via a
front panel 200-pin socket.
40-670A Very High Density Multiplexer Range:
198-Channel, 1-Pole (with isolation switching)
99-Channel, 2-Pole (with isolation switching)
99-Channel, 1-Pole (with isolation switching)
49-Channel, 4-Pole (with isolation switching)
49-Channel, 2-Pole (with isolation switching)
24-Channel, 8-Pole (with isolation switching)
24-Channel, 4-Pole (with isolation switching)
10-Channel, 16-Pole (no isolation switching)
10-Channel, 8-Pole (no isolation switching)
5-Channel, 32-Pole (no isolation switching)
5-Channel, 16-Pole (no isolation switching)
The majority of 40-670A 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 40-670A-022-198/1 multiplexer.
Versions with automatic isolation switching (see range
table above) connect only the active multiplexer bank to
the common terminal, thereby keeping capacitive loading
and leakage currents in large multiplexer systems to a
minimum. Larger multiplexers may be constructed by
daisy chaining the common signals from multiple modules.
(Multiple channel selection not available for this version)
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connector that has been superseded by a Pickering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.
