<p>The 441 Roller Lever D Limit Switch is a robust and reliable choice for industrial and commercial applications, designed to meet demanding operational requirements. Built with an aluminium housing, this limit switch offers durability while maintaining a lightweight profile at just 55 grams, making it easy to integrate into existing systems without adding unnecessary bulk.</p><p>This limit switch boasts a substantial rated current capacity of 1000 A, ensuring it can handle significant electrical loads effectively. With its IP65 degree of protection, the device is well-suited for environments where dust tightness and water resistance are crucial factors. The adherence to standards such as BG-GS-ET-14 and ENIEC 60947-5-3 further underscores its reliability and safety in various settings.</p><p>Designed with versatility in mind, the contact configuration includes one normally open (NO) and one normally closed (NC) contact. This dual configuration provides flexibility in controlling circuits within your application. The slow action switching type with positive break NC contact ensures precise operation by mechanically forcing the contacts apart when actuated, enhancing safety by guaranteeing circuit interruption under fault conditions.</p><p>The actuator type features an R300 roller plunger that allows for smooth mechanical interfacing with moving parts in your system. With an actuating speed of 0.3 m/s, it&#39;s capable of responding promptly to changes in position or motion within your machinery.</p><p>The switch&#39;s contact material is made from silver, known for its excellent conductivity and resistance to corrosion—ensuring long-term performance even under frequent use conditions. It has a fuse rating of 6 A which helps protect against overcurrent scenarios.</p><p>Installation is straightforward thanks to the M20 x 1.5 screw terminal type which accommodates cable cross-sections up to 0.5 sq-mm—ideal for connecting wires securely without hassle.</p><p>One notable feature is its impressive mechanical life expectancy of up to one million operations; this longevity translates into reduced maintenance needs and lower replacement costs over time—a critical consideration for any business aiming at maximizing uptime and minimizing downtime.</p><p>Overall, the 441 Roller Lever D Limit Switch offers a compelling blend of durability, performance, and compliance with international standards—making it an excellent choice for professionals seeking dependable solutions tailored towards rigorous industrial applications.</p>
