Honeywell Sensing & Productivity is Honeywell’s industrial sensing division, offering a variety of sensors and related equipment for aiding in automation. One such sensor is their NGCMB00PX01C-L40 limit switch. We’ve had some questions recently on the meaning of the “-L40” suffix and whether this switch is comparable to NGCMB00PX01C. Does this suffix change the switch’s specifications?
In this case, the “-L40” means the product has an improved cold-weather rating, going all the way down to -40C operating temperatures. It’s considered an upgrade to NGCMB00PX01C, and can drop in for the un-suffixed part.
