The Omron D4A-3115N is a rugged general-purpose limit switch equipped with a flexible rod actuator (cat whisker type) and a snap-action mechanism for reliable and quick switching. It features a 2-circuit SPDT double-break contact configuration, making it suitable for a wide range of industrial position-detection applications.
This model supports G1/2 conduit entry and offers high mechanical durability with a minimum of 1 million electrical operations at 10 A (125 VAC). With no built-in indicator, it is optimized for robust sensing environments where visibility is not required. The switch operates reliably from β20Β°C to 100Β°C and maintains performance in high-vibration or shock-prone areas, thanks to its strong internal construction.
Built to withstand harsh conditions, the D4A-3115N is rated IP67 and NEMA Type 1 to 13, ensuring water, oil, and dust resistance. Itβs ideal for machinery, conveyors, and automated systems requiring consistent positional feedback.
