D-SUB Connectors for Field Bus Systems
-with Screw Terminal Connection
SUBCON-PLUS
1. Short Description
The plugs are especially suited for use in RS 485 bus
systems in which an incoming and an outgoing bus
cable must be connected in one D-SUB connector.
SUBCON-PLUS can be connected quickly and con-
veniently under field conditions without soldering or
crimping tools. The plug-in contacts are connected to
numbered screw terminal blocks and it goes without
saying that there is a separate termination block for
each of the two cable entries. This produces a
systematic overview of the wiring and simplifies
every system start-up.
The connector is available as socket and pin version
suitable for nearly all bus systems. The terminating
resistors are connected at the start and end of the bus
to the free second termination block or, in some
versions, using a slide-type switch (version for
PROFIBUS).
The connectors, designed for the smallest dimen-
sions, can be used for transmission speeds up to 12
Mbit/s. The shielded connector housing guarantees
high immunity to interference.
The direction from which the cables are introduced
can be decided on-site. The connection block can
be installed either in the upper or lower shell of the
housing. It is thus possible to introduce the cable at
an angle of 0° ... 90° from the right or the left.
