Obsolete Omron Parts

Omron has discontinued whole PLC generations — C500, C200H, CQM1, CPM1 — but the machines they control are still running, and a working machine does not owe anyone a redesign. We stock what we can and source the rest through the independent channel, with the condition of every unit stated honestly before you pay.

What "obsolete" means here. The series below are discontinued by Omron — no factory repair, no new production. Parts come from the independent distribution channel: new old stock where it exists, otherwise used units that are visually checked for condition and correct part marking before dispatch. Units are not powered up or bench-tested unless explicitly stated. Every part carries the same 12-month warranty as our current-range stock.

No dedicated page does not mean no supply. For these series — and anything else with an Omron label on it — send the exact model and suffix and we will check the channel:

Not sure whether to repair or migrate?

If the failed part has a documented successor, our Omron Replacement Guide shows the mapping and the end-of-production dates. If the whole platform is end-of-life, the honest comparison is: cost of spares to keep running versus cost of a rack, wiring and program migration. Send us the model and the machine's situation — we sell the spares, and we will tell you plainly when a migration is the better spend.
