These are examples of Rode's attention to detail in design. The longer pin is pin 1 and is connected to ground. It's longer on purpose so that when plugging into the cable, the ground connection is the first to contact, thus protecting the mic's internals if the cable has any voltage on it.
Also in the same area .. if you haven't read in the Rode mic manuals, make all your 48volt powered mic. connections and only then switch the 48volts ON.
