A high-quality RS232 cable is essential for any reliable shop floor communications network. Our cables are modular to make connecting your machines a snap.

Each cable is terminated with RJ45’s so that you can still string this cable through conduit or tight spots on your machine. We provide you with the properly pinned out 25pin or 9pin adapter to plug right on the end of our cables.

Cables are available in lengths from 25’ to 300’. For more info on our adapters see our RS232 Adapter Page
