Relialign™ Commercial Door Interlocks

Product Announcement from Honeywell Sensing and Internet of Things


Honeywell’s Relialign™ CDI Series Commercial Door Interlock Switches are designed for swing door applications that include commercial elevators, dumbwaiters, and platform lifts. The door interlock holds the door in place and prevents it from being opened when not desired (e.g. the elevator/lift car is not present at the door). A number of design features contribute to its enhanced safety, reduction of nuisance stoppages and call-backs, as well as simplified wiring and installation. The CDI Series provides an alternative to large, installation-intensive interlocks and OEM custom-made products.

The CDI Series is an extension of Honeywell’s successful swing-door interlock switches for residential applications: a metal housing version (RDI Series, released in June 2009) and a plastic-molded housing version (RDI2 Series, released in June 2010). The CDI Series leverages similar design technology of the RDI Series’ platform while adding the robustness needed for the commercial industry. The CDI Series has a greater pull force than the RDI and RDI2 Series (675 pounds vs. 150 pounds) and a longer mechanical life (one million cycles vs. 55,000 cycles) - important features for commercial applications.
