The W5RP is a 48 contact addition to the virtually indestructible
whirlwind Mass Connector family. This new design uses crimp type,
replaceable pins and sockets. Like all Mass connectors, the W5RP
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.
