The Omron CJ1W-V680C11 is an ID Sensor (RFID) Module built on the CJ1W family, designed to read RFID tags into a CJ-series PLC rack over the standard CJ backplane. Field-side termination is circular, matching the antenna/read-head cabling Omron uses across the V680 RFID lineup; the rack-side connection goes through the CJ backplane like every other CJ1W module.
Spare, second-source, and BOM freeze notes
Both parts share the same product class, so a panel specified around CJ1W-V600C11 accepts CJ1W-V680C11 in the same slot. For a slot currently populated with CJ1W-V600C11, this part is a same-frame alternate; verify tag population (V680 vs V600 series tags) and ladder/IO table entries before specifying as a direct cross.
Handling and panel-side notes
Circular field connector means the antenna cable gland is the panel-side decision, not the module footprint — keep the bend radius in spec when routing the read-head lead.
