The Whirlwind W2 is a 61 contact, quick disconnect connector 
system based on the proven MIL-26482 multipin standard. The pin 
and socket modules are shell size 24 with a standard 61 contact 
insert arrangement. The solder style contacts are permanently 
mounted in resilient rubber insulators to provide years of trouble 
free service.
Whirlwind manufactures a robust aluminum backshell to protect 
the soldered connections and provides a waterproof mesh grip for 
an absolutely reliable strain relief on the cable. The W2 system 
utilizes a 61 pin male insert in a plug shell, with a quarter-turn 
locking ring and a 61 socket female insert in a receptacle shell with 
studs, that mates with the male plug shell.
Whirlwind provides the W2 in four standard configurations, male 
and female inline and male and female chassis mount. The W2 can 
be used to interconnect up to 20 balanced, shielded signal lines.
