<p>When it comes to selecting a reliable and robust switch for industrial and commercial applications, the focus often falls on durability, compliance with standards, and precise operation. This particular switch offers a comprehensive solution tailored for demanding environments.</p><p>Starting with its construction, this switch is encased in grey cast iron which is galvanised for enhanced resistance against environmental factors. This solid housing ensures longevity even under rigorous conditions while offering an impressive IP65 degree of protection. This means it is dust-tight and protected against water jets from any direction, making it suitable for outdoor or harsh indoor environments.</p><p>The switch complies with INMETRO and CCC standards, ensuring adherence to international safety and quality benchmarks. These approvals provide peace of mind that the product meets stringent regulatory requirements.</p><p>Functionality-wise, the contact configuration features one normally open (NO) and one normally closed (NC) auxiliary contact. This setup allows flexibility in control circuit design depending on operational needs. The single auxiliary contact adds another layer of functionality without complicating installation or maintenance processes.</p><p>This device employs a mechanical switching type facilitated by a fork roller lever actuator. Such an actuator type is ideal for applications requiring precise actuation as it operates effectively at low actuating speeds down to 1 mm/min. The contacts are made from AgSn0 material known for excellent conductivity and wear resistance—key attributes when dealing with frequent operations or high loads.</p><p>For connectivity, the terminal type used is M20 x 1.5 screw terminals which offer secure connections that can withstand vibrations common in industrial settings.</p><p>Another notable feature is its mechanical life rated at 5 million operations—a testament to its reliability over extended periods of use without significant degradation in performance. Additionally, the contact opening measures (2) 2.5 mm which provides adequate separation distance ensuring safe disconnection during operation cycles.</p><p>In summary, this switch stands out due to its robust construction, compliance with international standards, versatile contact configuration options along with its long mechanical life expectancy—all essential characteristics sought after by professionals who demand dependable performance from their electrical components.</p>
