Is the Rockwell 1746-HSCE discontinued?
On ECS's lifecycle assessment, the 1746-HSCE has been cancelled: no longer sold as a current product, though spares may remain available for a period.
Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. 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 a high-speed counter module
High-speed counter applications are sensitive to encoder type, pulse rate, wiring mode, input voltage and the way counts are consumed by the PLC program.
A successor may offer equal or better headline performance while still requiring changes to terminals or logic. We would document the complete signal path and test the migration against the real machine speed before treating the replacement as proven.

Common questions about the 1746-HSCE
Is the Rockwell 1746-HSCE discontinued?
On ECS's lifecycle assessment, the 1746-HSCE has been cancelled: no longer sold as a current product, though spares may remain available for a period.
Can I still buy a 1746-HSCE?
Not as a normal new product. Remaining distributor stock or designated spares may still be available. Buy any you need now.
Know where every unit is before one fails.
A Capture audit finds every 1746-HSCE 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
