The aluminum X-style body carries a boot-sealed actuator and screw terminals, rated IP67 and NEMA 1, 2, 3, 4X, 5, 6P, 12, and 13 — meaning it handles hose-down cleaning and outdoor installation without an extra enclosure. ## Contact ratings and travel Contact form is DPDT sequential operation — the normally-open and normally-closed poles do not break-make simultaneously, which matters for safety interlocks where a make-before-break or break-before-make sequence is required. AC rating is 3 A at 250 V; DC rating depends on voltage and load type: 5 A at 14 V resistive, 3 A at 30 V resistive, 0.4 A at 125 V inductive or resistive. Pretravel is 17°, overtravel 65°, total travel 90°, with 5° differential travel — the switch resets within a 5° release window, giving predictable repeatability on cam profiles. ## Mounting and actuation Surface-mount body with two 0.2 in mounting holes spaced 59 mm vertically and 29 mm horizontally. The switch ships without an actuator — the compatible type is roller arm plunger, and a boot is included to seal the actuator entry. Maximum operating torque is 3.54 in-lb; the switch accepts CCW/CW directional movement. Operating temperature range is -40 °F to 212 °F.","metaTitle":"Omron D4A2717N Limit Switch, DPDT, IP67, 3A@250VAC","metaDescription":"Omron D4A2717N plug-in limit switch, DPDT sequential, IP67, NEMA 4X/6P, 3A@250VAC, 5A@14VDC.
