The momentary action means the contacts return to their normal state as soon as the plunger is released — standard for position sensing on conveyor diverters, transfer stations, and machine guards where the switch must not latch. The aluminum body and stainless steel roller handle the mechanical abuse of a material-handling line. IP67 sealing keeps washdown and dust out, and the NEMA 1, 2, 3, 4X, 5, 6P, 12, 13 ratings cover indoor and outdoor enclosures — so it drops right into the topology of a zoned conveyor system without needing a separate enclosure. AC contact rating is 3 A at 250 V, which handles pilot-duty control circuits for contactors and relays on 120 V or 240 V lines. The DC side is more nuanced: 3 A at 30 V (resistive or inductive) covers most 24 VDC sensor and PLC input loads, while 5 A at 14 V suits low-voltage automotive or battery-powered sections. The 0.4 A at 125 V DC inductive rating is the one to watch — if you're switching a DC solenoid or brake coil at that voltage, stay under 0.4 A or add a suppression diode across the load. ## Mechanical fit notes Surface-mount body with two mounting holes. Body dimensions are 2.97 in height, 1.65 in width, 1.73 in depth. The roller plunger has 0.06 in pretravel and 0.2 in overtravel, with total travel of 0.26 in — enough to absorb overrun on a conveyor divert arm without damaging the switch. Screw terminals accept standard control wiring; the boot-sealed actuator keeps contaminants out of the plunger shaft.","metaTitle":"Omron D4A2510N Limit Switch, DPDT, IP67, Roller Plunger","metaDescription":"Omron D4A2510N limit switch with momentary action, DPDT contacts, IP67, roller plunger actuator.
