<p>When it comes to selecting reliable components for industrial environments, understanding the precise specifications of each product is crucial. This particular non-illuminated emergency stop button is designed with robustness and safety in mind, making it a suitable choice for demanding applications such as mining, construction, and heavy industry.</p><p>First and foremost, the button features an IP66 degree of protection. This ensures that it is dust-tight and protected against powerful water jets—a vital attribute for harsh operational settings where exposure to dust and moisture is common. The standards compliance includes EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529 along with UL 508 and CSA C22.2 No. 14 certifications which affirm its reliability across international markets.</p><p>Operating efficiently within a wide ambient temperature range from -30 to 70 degrees Celsius means this device remains functional in extreme conditions—from freezing cold winters to scorching hot summers—without compromising performance or safety.</p><p>The connection type employs screw terminals which are known for their secure fastening capability ensuring consistent electrical contact over time. With a rated insulation voltage of 690 V and an impulse withstand voltage of up to 4 kV, this button can handle significant electrical loads safely.</p><p>Its contact configuration comprises one normally closed (1NC) contact setup which plays an essential role in fail-safe operations by maintaining circuit continuity until deliberately interrupted. The actuator type features a mushroom design with a diameter of 40 mm providing easy access during emergencies while the maintained function ensures that once activated it remains engaged until manually reset—a critical feature for emergency stop scenarios.</p><p>Aesthetic considerations have not been overlooked; the button&#39;s red color is universally recognized as an indicator for emergency stops enhancing its visibility even from afar amidst complex machinery setups. The metal bezel material adds durability further extending its lifespan under rigorous usage conditions.</p><p>Finally given that both cutout size and actuator diameter are standardized at 40 mm installation becomes straightforward facilitating quick integration into existing panels or systems without requiring extensive modifications thereby minimizing downtime during upgrades or replacements.</p><p>This component stands out as a dependable choice when prioritizing safety efficiency and compatibility within high-demand industrial environments.</p>
