The Omron D4C0033 is a limit switch head from the D4C series, fitted with a cross roller plunger actuator on top. It's the sensing end of a modular limit switch assembly — the head mounts onto a D4C-series switch body (like the D4C1633) to form a complete sealed limit switch. The cross roller plunger actuates from linear motion in any direction across the roller, making it a good fit for cam tracks, slide gates, or any application where the actuator sees a wiping or rolling contact rather than a straight butt-on hit. Rated IP67, with sealed cable entrance, sealed plunger section, and sealed switch section, this head handles washdown environments and outdoor exposure. The NEMA enclosure rating covers types 1, 3, 3R, 4, 5, 6, 12, and 13 — so it's at home in a food processing line, a wet chemical area, or a dusty conveyor gallery. The stainless steel arm and fixed 1.26 in arm length add corrosion resistance and repeatable positioning.
Operating force is 17.65 N. Pretravel is 0.07 in, overtravel 0.12 in, and differential travel 0.01 in. The arm width is 0.17 in, and the cross roller plunger has a 52.04 in-lb operating torque rating. That torque figure tells you the roller can handle side loads from a cam follower without binding or premature wear — it's not just a light-touch sensor.
