WHIRLWIND W5IRP Micro MASS Connector, Input

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.

The rugged metal shell protects against moisture and physical abuse.

The hermaphroditic design eliminates stocking and logistical problems encountered with male/female connector systems by reducing the number of required parts.

All MASS connectors include a heavy-duty dust cap. Inlines also include strain relief.
