<p>When it comes to selecting reliable and robust control devices for industrial applications, this non-illuminated mushroom pushbutton stands out as a solid choice. Designed specifically for demanding environments such as mining, construction, and heavy industry, it offers both durability and efficiency.</p><p>Boasting an IP66 degree of protection, this pushbutton is well-equipped to handle the harshest conditions. It effectively resists dust ingress and powerful water jets from any direction, ensuring uninterrupted operation even in challenging settings. The device adheres to rigorous standards including EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529 as well as UL 508 and CSA C22.2 No. 14 approvals—providing assurance of its quality and safety compliance.</p><p>One of the key features is its wide ambient temperature range from -30 to 70 degrees Celsius. This ensures reliable performance across various climates without compromising functionality or safety. The connection type is screw-based which facilitates secure installation while maintaining electrical integrity over time.</p><p>The rated insulation voltage of this unit is an impressive 690 V with a rated impulse withstand voltage of 4 kV—demonstrating its capability to handle high voltages safely. Its contact configuration consists of one normally closed (1NC) contact which suits many standard control circuit requirements.</p><p>A notable aspect is the actuator type—a mushroom design with a diameter of 40 mm that provides easy operation under pressure or emergency situations. Its maintained function means once activated; it stays engaged until manually reset—a critical feature for certain industrial processes requiring constant attention.</p><p>Constructed with a metal bezel material adds another layer of robustness against physical impacts or wear-and-tear over prolonged use periods while maintaining aesthetic appeal within control panels or operator stations.</p><p>With a cutout size also at 40 mm matching the actuator diameter ensures seamless integration into existing systems without needing additional modifications during installation phases reducing downtime significantly when upgrading equipment across facilities globally if necessary</p><p>Finally offered in green button color aligns perfectly with standard signaling conventions making identification straightforward even amidst complex setups aiding operators&#39; response times effectively during operations</p><p>In summary whether you&#39;re involved in designing new installations upgrading legacy systems across sectors like mining construction heavy industries alike considering these specifications will help determine if this product meets your technical requirements efficiently</p>
