The Elinchrom PC to 3.5 mm Sync Cord (16'/5.0 m) works with their Universal Remote Control. It is compatible with Style, Style S, Style RX, FX, BX, BXRi and D-Lite flash heads. It's also compatible with Chic 1 and 2, Digital 1 and 2, and Digital RX 1200 and 2400 power packs as well as the Ranger Quadra battery pack.
I bought it for my Elinchrom two-light kit. One of the sync cords died on me a few months ago, and I really needed to have an additional one, just to be on the safe side. It's always good to have an extra one, and to be prepared. And it's pretty long, too. That's nice!
It works great and is durable but it doesn't fit snug into the female sync mount. I don't know if it's the mount or the cord but we've bought two of both pieces and they fall out too easily.
