The Omron D4CC1032 is a metallic-body limit switch with a roller plunger actuator, SPDT contact form, and momentary action — meaning the contacts return to their resting state the instant the plunger is released. The IP67 rating means the switch body and the boot-sealed actuator withstand direct hose-down and temporary immersion, so it's suited for washdown zones in food processing or outdoor conveyor lines. The 1 A @ 125 V AC contact rating is the headline limit for resistive loads; with no DC rating listed, this switch is intended for AC control circuits only.
Mounting and Connection Reality
Surface-mount body with two 0.2 in mounting holes — standard M4 or #10 hardware. The 4-pin M12 connector (micro-change style) is the field connection; no pigtail to strip, no terminal screws to torque. That connector is the first thing to check on a line-down call: a bent pin or corroded contact in the mating cable will look like a dead switch. The aluminum body and stainless steel roller hold up in washdown and corrosive atmospheres, backed by NEMA 3, 4, and 13 ratings for indoor and outdoor enclosures.
