This is the head only — it mounts to the D4C switch body to form a sealed limit switch assembly. The stainless steel arm (2.32 in length, 1.15 in depth) resists corrosion on washdown lines or outdoor conveyor tracks, and the IP67 rating means the switch section and cable entrance stay sealed against dust and temporary water immersion — out here in the grease, that's what keeps a position sensor alive past the first hose-down. The 5.69 N operating force and 25° pretravel (with 40° overtravel and 3° differential travel) define the mechanical snap action: the roller lever needs about half a kilogram of force to trip, and the 25° of free travel before the contacts switch gives you room to adjust the cam or dog position without losing the signal. The 52.04 in-lb operating torque tells you the lever can handle a decent whack from a cam follower without bending. Fixed arm adjustability means the roller angle is set at the factory — no field bending, so order the right approach angle. ## Sealing and approvals — the real-world gate IP67 is the ingress floor, but the NEMA enclosure ratings (1, 3, 3R, 4, 5, 6, 12, 13) tell the full story: this head survives rain, sleet, hose-down, and temporary submersion (NEMA 4/6), plus the oil and dust of a typical machine-tool environment (NEMA 12/13). CCC, CSA, EN, and UL Listed approvals mean it passes inspection for export panels and safety-rated machinery. The sealed switch section and sealed cable entrance are the features that actually keep washdown water out of the contact block — not just the housing gasket.","metaTitle":"Omron D4C0020 Limit Switch Head, Roller Lever, IP67, Mature","metaDescription":"Omron D4C0020 D4C series limit switch head with roller lever plunger, IP67 sealed, NEMA 4/6 rated, stainless steel arm.
