Description

<p>When selecting components for industrial applications, reliability and compliance with standards are paramount. This particular product is designed to meet the demanding needs of mining, construction, and heavy industry sectors. It operates efficiently at a rated voltage of 24 VAC/DC, ensuring compatibility with various power systems.</p><p>The mushroom actuator type, with a diameter of 40 mm, provides an ergonomic design that is easy to operate in high-stress environments. The illumination feature utilizes a red LED lamp housed within an LED block, enhancing visibility even in low-light conditions. The maintained function ensures that once activated, the switch remains in its position until manually reset—a critical feature for safety applications.</p><p>Constructed to withstand harsh conditions, this device boasts an IP66 degree of protection. This rating indicates its resilience against dust ingress and powerful water jets from any direction—ideal for rugged outdoor environments or dusty indoor settings common in industrial sites.</p><p>Temperature tolerance ranges from -30 to 70 degrees Celsius, allowing it to perform reliably across various climates without compromising functionality. The connection type employs screw terminals for secure wiring connections—an essential factor when considering vibration-prone installations typical in heavy industries.</p><p>Adhering to rigorous international standards such as EN IEC 60947-5-1 and UL 508 ensures that this product meets both European and North American safety requirements. Its rated insulation voltage stands at 690 V while offering a robust impulse withstand voltage of up to 4 kV—these specifications underscore its capability to handle electrical surges safely.</p><p>The contact configuration includes one normally open (NO) and one normally closed (NC) contact which offers flexibility for different control circuit designs. Additionally, the rated thermal current capacity is set at 10 A—a suitable range for most industrial control circuits.</p><p>The metal bezel material not only adds durability but also complements the rugged design necessary for tough working conditions. With a cutout size matching the actuator diameter at 40 mm, installation is straightforward and compatible with standard panel setups.</p><p>This comprehensive package includes everything required: operator unit, contact block assembly, maintained accessories along with the LED block—all designed to integrate seamlessly into existing systems or new projects alike.</p>
