UNIVERSAL UNCOMMITTED BACKPLANES, 96-Pin
3U Backplanes
with 4 Layer Construction
Universal (uncommitted) multilayer backplanes
are designed for unique one of a kind applica-
tions requiring custom wiring, or for custom
development work. They use 96-pin (press-fit
type) connectors and conform to DIN 41612, they
have three-level wire-wrap length pins on all con-
nector leads. None of the pin positions are com-
Model UM21A3U-20 Universal (uncommitted) 3U backplane
mitted to power, ground or signal use; your appli-
cation will dictate these pin assignments.
These backplanes are designed for maximum
utility by incorporating two parallel rows of ground
pins (32 pins per row) for each connector slot and
two segment of power pins on one row of 6 pins
each (total of 12) for +5V (or main voltage) power
pins. Two additional voltage levels may be dis-
tributed to the board (as AUX A & AUX B) with
these power pins conveniently distirbuted over
the board. Power input by means of power bugs
and/or Mate-N-Lock connectors are available.
Features Include:
Dwg. A: 3U version with .8” connector spacing.
