Overview
The Omron D4C-1620 is a compact enclosed limit switch engineered for precision control in industrial automation. Featuring a roller lever design, this switch delivers reliable electrical isolation with SPDT (Single Pole Double Throw) contact configuration rated at 5A 250VAC and 4A 30VDC. Sealing characteristics meet IEC IP67 protection with triple-sealed construction: plunger section sealed via nitrile rubber packing, switch section sealed via nitrile rubber cap, and cable entrance sealed via encapsulating material. Manufactured in Japan and shipped new in box with pre-attached 3m cable.
