The Omron NSH5-232UL-10M is a 10-meter communications cable assembly purpose-built for the NSH5 series of human-machine interfaces. It connects the HMI to a controller or peripheral over a serial RS-232 link, carrying both power and signal in a single shielded jacket.
What the 10-meter length means for your panel layout
10 meters (32.8 feet) is the standard reach for a cabinet-to-floor HMI or a panel-to-remote-I/O drop. It gives enough slack to route through cable trays without a junction, but it is not a long-haul run — RS-232 tops out reliably around 15 m at 9600 baud, so this cable stays within the protocol's sweet spot. For longer distances you would step to an RS-422/485 adapter or a network gateway.
