D4NA-4132 OMRON 240VAC/10A Roller Plunger Limit Switch

Description

The OMRON D4NA-4132 is a high-precision safety limit switch engineered for industrial automation and elevator safety systems. It features a 1NC/1NO snap-action contact mechanism with a direct opening mechanism to ensure circuit interruption even in the event of contact welding. This model is equipped with a 9.5mm diameter resin roller plunger actuator and a single M20 conduit entry. It operates reliably within a voltage range up to 240VAC and a rated current of 10A, maintaining an IP67 protection rating for harsh environments. The switch is designed for high durability with a mechanical life of 15,000,000 operations and an operating temperature range of -30 to 70°C.
