The Whirlwind W3RP is a 122 contact version of the virtually
indestructible whirlwind Mass Connector. This new design uses crimp
type, replaceable pins and sockets. Like all Mass connectors, the
W3RP has equal numbers of both pins and sockets within the resilient
rubber insert. This arrangement allows two identical contact inserts to
mate, requiring only a panel mount or inline housing to complete the
assembly. Housings are made from machined aluminum and the
threaded locking ring ensures positive connection even under
adverse conditions. When mating two inline connectors, one locking
ring is merely unscrewed to expose threads, which are gripped by the
other locking ring.
To properly mate Mass connectors, unscrew the locking rings to
expose the inserts, align the inserts and push together using only
hand pressure and then screw the locking ring on to secure the
connection.
Due to the unique hermaphroditic design the usual connector
designations of male and female do not apply, therefore Mass
connectors are specified as Outputs and Inputs. An Output wired
connector must mate with an Input connector configuration. The
whirlwind wiring standard is odd numbered cable pairs attached to
pins and even numbered cable pairs attached to sockets in the Output
connector. Input wiring has odd pairs attached to sockets and even
pairs attached to pins. For example, channel one is on pins in the
Output connector and mates with channel one on sockets in the Input
connector, which maintains color coding throughout the system. For
planning system layout, whirlwind standard starts at the stage box and
designates the first connector as an Output.
Cables with Mass connectors at both ends require one end to be
wired as an Output and the other wired as Input. Each wire must
connect to a pin at one end and the same numbered socket at the
other. The W3RP will accommodate up to 40 balanced, shielded
signal lines.

Check for proper wire strip length by
pushing wire into a contact and looking to
see the wire strands through the hole in
the side. Load the contact into the crimp
tool locator and push the wire into place.
Squeeze the handles while making sure
that the wire stays in the wire hole . The
crimper is a full cycle racheting type and
can only be released by completing the
cycle, at which point the crimp contact will
pull freely from the tool. Inspect the
connection and continue, following the
color code to apply pins and sockets to
the proper wire pairs.
Load the pins and sockets into the
insert housing according to the pin out
color code. Contacts are inserted into the
hard plastic wafer and pushed into place
with the red handled end of the insertion
tool or small needle nose pliers. Fully
inserted contacts are locked in place by
spring metal retention clips embedded in
the plastic wafer. In the event a contact
must be removed from the insert use the
white handled, extraction end of the
contact tool. Carefully slip the tool into the
plastic wafer until the small hole in the end
of the extractor is even with the surface of
the wafer. Do not force the tool in as it is
easily deformed. Only when the tool is
properly seated will the spring fingers
release, allowing the contact to be
removed. If the wire is still attached, gently
pull the wire to remove it. If the wire is
broken, push the contact from the rubber
face side with an opposite contact until it
is exposed in the back.

The W3RP is a rear insert, rear release crimp type connector. Contacts are
loaded into the insert body and removed from the rear (wiring side) of the
housing. To prepare the wires for use, follow the diagram for removing the
jacket and the foil shield from the cable pair. Be careful not to nick and do not
tin the ends of the wire being stripped. Insulate the drain wires with the clear
PVC tubing and use the heat shrink tubing over the foil of each pair.
The whirlwind M1R-Tool Kit contains the required tools to attach the
contacts to the wires and to load or remove them from the insert housing. The
crimp tool body is a mil spec Daniels AFM8 with a Whirlwind K13-3 contact
locator. The contact insertion/extraction tool is an AMP 91067-2.
Before attaching contacts to the wires, the selector knob on the top of the
crimp tool must be set for the proper gauge. Setting 5 is for 24 AWG such as
whirlwind multipair cable and setting 6 is for 22 AWG such as Belden 8451 and
1266A.
