The Cutler-Hammer® Premium+ Series inductive proximity sensors have improved sensing performance, product durability and selection. This improved line of sensors carries the Premium+ Series name because we have upgraded the design to a rugged stainless steel body, shock resistant front caps and impact absorbing potting compound. Also, the Premium+ Series line now includes a choice of AC/DC and DC-only, 12, 18 and 30 mm sensors with unmatched noise immunity of greater than 20V/meter.
