It carries a 10 A AC contact rating at 250 V and a multi-voltage DC rating that spans 0.4 A at 250 V up to 10 A at 14 V or 8 V, with 6 A available at 30 V DC — so the DC curve matters for your actual load voltage, not just the highest number. The IP67 rating means the switch body and the boot-sealed actuator withstand washdown and temporary immersion — suitable for food processing lines, outdoor conveyor transfer points, or any area where a hose-down is part of the sanitation cycle. The NEMA enclosure rating covers 1, 2, 3, 4X, 5, 6P, 12, and 13, which aligns with indoor and outdoor industrial locations where corrosion resistance and dust-tight sealing are specified. ## Mechanical precision and mounting Pretravel is 12°, overtravel 70°, and total travel 85° with a differential travel of 4° — these numbers define the switch's repeatability in cam-actuated or position-sensing applications. The 1.77 in-lb maximum operating torque tells you the force needed to trip it; a lighter cam profile may not reliably actuate it. Mounting is surface-style with two 0.2 in holes spaced 59 mm vertically and 29 mm horizontally center-to-center. The aluminum body measures 2.97 in high, 1.65 in wide, and 1.73 in deep. Screw terminals accept field wiring directly — no pigtail or connector to source separately. The D4A1103N carries a mature lifecycle status — it is not in active new-product introduction but remains in the Omron catalog as an established, field-proven design. Approvals include UL Listed, CSA, and CCC certification, covering North American and Chinese regulatory requirements. Compliance documentation for RoHS and REACH is standard for Omron industrial switches of this era; the UL and CSA marks are the primary authority signals for panel builders and site electrical engineers.","metaTitle":"Omron D4A1103N Limit Switch, SPDT, 10A @ 250V, IP67","metaDescription":"Omron D4A1103N plug-in limit switch.

A direct sibling would share the same body style, mounting footprint, and electrical ratings but differ in actuator type or included accessories. For a pin-compatible drop-in, verify the actuator form factor and pretravel/overtravel angles match your cam profile."},{"question":"What action does the D4A1103N use?","answer":"Momentary action — the switch returns to its normal state as soon as the actuator force is removed. This is the standard for position-sensing and interlock circuits where the switch must not latch."},{"question":"What compliance documentation is available for the D4A1103N?","answer":"The D4A1103N carries UL Listed, CSA, and CCC approvals.
