The Omron CS1W-CN133 is a 32.81-foot (10-meter) I/O cable assembly for the CS1 Series PLCs. Both ends use rectangular connectors (control side and process side) so the cable swaps in and out of the PLC rack and remote I/O block without terminal-block rewiring. The bulk-packaged cable carries CE, Lloyd, and NK approvals.
The CS1W-CN133-B2 is the same cable with a 12-meter length (39.37 ft); all other specs—rectangular connectors, approvals, CS1W series—match. If your BOM calls for a 10-meter I/O cable, the -CN133 fits; if the panel layout needs a longer run, the -B2 variant drops in without any wiring change. The shortest sibling, CS1W-CN521 (5 m), occupies the same connector footprint for tight cabinets.
The CS1W-CN133 is listed as active on Omron's lifecycle status. For a common I/O cable used in line-down swaps and expansion, that means no near-term end-of-life notice to track.
