What it is
The Omron CS1W-CIF31 is a cable assembly in the CS1W series, built for use with the Omron CS1 Series of PLCs. It carries the CS1W-CIF31 order code and ships in bag packaging rather than a bulk pack. Functionally it sits in the same accessory family as the CS1W-CNxxx programming and interface cables that connect a CS1 CPU to a host port or peripheral device.
Functional second source within the CS1W family
Same-family peer on record: CS1W-CN118 — 0.328 ft (100.00 mm), CS1W series, bulk package, RJ45 control side, D-Sub process side, for the Omron CS1 Series. Connector mix and length differ from the CIF31, so treat it as a like-for-like candidate for review rather than a confirmed drop-in; verify the CS1 CPU host-port pinout before substituting.
