Is the Omron CPM1-CIF11 discontinued?

The CPM1-CIF11 has been cancelled (since March 2015): no longer sold as a current product, though spares may remain available for a period. Its successor is the CP1W-CIF11.

Source: OMRON Corporation (Japan). Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.

What Cancellation means for you

You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run.

Before replacing it

A replacement decision starts with understanding how the existing machine uses the part, not simply finding something with a similar specification. We would document the electrical interfaces, configuration, software dependencies and surrounding components before choosing an alternative.

That establishes whether the part can genuinely be swapped or whether the change reaches into a wider section of the control system, and turns an obsolete-spare problem into a planned engineering task with a tested recovery route.

Know where every unit is before one fails.

A Capture audit finds every CPM1-CIF11 on your site, photographs it where it sits and checks it against manufacturer lifecycle status, so you know your exposure and where your spares are before a failure stops a line.

  • Every device located, photographed and lifecycle-checked
  • Findings report, plus a populated Command Centre
  • No production downtime
