<p>For professionals in the industrial and commercial sectors, selecting the right switch gear is pivotal to ensuring operational efficiency and safety. This particular limit switch, designed with precision and reliability in mind, offers a robust solution tailored for demanding environments.</p><p>Operating at a rated voltage of 400 VAC and a current of 4 A, this device is engineered to handle substantial electrical loads efficiently. The housing material is crafted from grey cast iron, galvanized for enhanced durability and resistance against harsh conditions. This ensures longevity even in challenging settings, making it an excellent choice for various applications.</p><p>The product boasts an impressive degree of protection at IP65. This rating guarantees that the device is dust-tight and protected against water jets from any direction, providing peace of mind when used in environments where exposure to dust or moisture is inevitable. Compliance with EN IEC 60947-5-1 standards further underscores its reliability and adherence to international safety norms.</p><p>Its contact configuration features one normally open (NO) and one normally closed (NC) contact setup. This duality allows for versatile integration into existing systems requiring both open and closed circuit functionalities. The switching type employed here is slow action, which provides controlled operation—ideal for processes needing precise actuation timing.</p><p>The actuator type utilized is an offset roller lever, known for its adaptability across different mechanical interfaces. With an actuating speed of just 1 mm/minute, this switch delivers meticulous control over operations that demand gradual engagement or disengagement.</p><p>Constructed with silver contacts, the device ensures excellent conductivity while minimizing wear over time—a critical factor for maintaining consistent performance across its extensive mechanical life span of up to ten million operations.</p><p>Safety remains paramount; hence the fuse rating stands at 16 A gG D-Fuse, safeguarding against potential overloads. Additionally, it accommodates a cable cross-section of 1.5 sq-mm—facilitating straightforward connectivity within your system&#39;s wiring architecture.</p><p>Finally, boasting two contact openings each measuring six millimeters enhances its versatility by allowing multiple connection configurations as per specific needs.</p><p>In sum: this limit switch combines rugged construction with precise functionality suitable for rigorous industrial use cases where reliability cannot be compromised.</p>
