What this relay unit sits next to on the DIN rail
The Omron 61F-11NL4K is the 61F-11NL4K order code from the 61F general purpose relay family, listed as a relay unit in the bulk pack option that ships with the standard control-panel accessory kit. The 61F line is Omron's classic general-purpose relay family — used as the auxiliary switching element sitting beside timers, level controllers and interface relays in motor control and process panels. Because the part reads only an order code, a series identifier and a bulk-package flag, this is a mature catalogue entry — the kind of part a maintenance buyer pulls out of the BOM when an old machine's relay unit finally gives up, not a new-design pick. No coil voltage, contact arrangement or switching-current figure is captured on this row, so the controlling specifications (coil, contacts, terminals) must be read off the datasheet before a wiring decision is committed.
Lifecycle and the procurement reality
The lifecycle record carries an Active product-status entry, paired with a mature stage tag — a posture typical of long-running Omron 61F SKUs that are still in regular production for spare-parts and panel-builder demand but no longer sit on the front of the new-release catalogue. That posture suits both the controls integrator filling a panel build and the maintenance planner covering a line-down spare — both want genuine Omron stock with full traceability, neither needs a same-day-shipment promise.
