<p>When considering accessories for industrial applications, it&#39;s crucial to choose products that balance durability with functionality. This accessory is designed specifically for demanding environments such as mining, construction, and heavy industry. Its robust design ensures reliable performance across a wide range of conditions.</p><p>The unit operates at a rated voltage of 12 VAC/DC and features an illuminated design that enhances visibility in low-light settings. The illumination is provided by a built-in LED lamp, which offers energy efficiency and long-lasting performance. The green lamp color signifies operational readiness or active status, while the button itself is color-coded with green on the upper part and red on the lower part to clearly indicate &quot;On&quot; and &quot;Off&quot; states.</p><p>In terms of protection, this accessory boasts an IP66 rating for its front panel, ensuring it is dust-tight and protected against powerful water jets—ideal for harsh outdoor environments. The terminal section has an IP20 rating, suitable for indoor use where direct exposure to elements isn&#39;t a concern.</p><p>Adhering to multiple international standards such as EN IEC 60947-1, EN IEC 60947-5-1, UL 508 among others ensures compatibility and safety across various installations worldwide. These certifications reflect its compliance with rigorous quality benchmarks necessary for industrial-grade equipment.</p><p>The product can operate efficiently within ambient temperatures ranging from -25&#176;C to 70&#176;C—a testament to its versatility in extreme climates. With a rated insulation voltage of 690 V and a rated impulse withstand voltage of 6 kV, it provides robust electrical protection under standard operating conditions.</p><p>Featuring a contact configuration of 2 normally closed (2NC) contacts alongside a flush/extended actuator type offers flexibility depending on user needs or spatial constraints in installation areas. Additionally, the light blocks type being LED block further enhances reliability through reduced maintenance needs compared to traditional lighting solutions.</p><p>Designed with user convenience in mind, this accessory includes all essential components: operator unit contact block holder along with the LED block ensuring straightforward assembly without additional purchases required post-installation.</p><p>The bezel material made from durable plastic complements its rugged application while maintaining lightweight properties ideal when frequent handling might be necessary during routine inspections or adjustments onsite.</p><p>Finally fitting into standard cutout sizes at just 22 mm makes integration into existing control panels seamless whether upgrading current systems or implementing new setups entirely—streamlining processes significantly over time without compromising efficiency nor safety aspects inherent throughout each component&#39;s lifecycle usage expectancy overall!</p>
