<p>For professionals in the electrical engineering and automation sectors, finding a reliable control component is essential. This non-illuminated push button offers robust features tailored for industrial and commercial applications. With an IP66 front degree of protection, it ensures resilience against dust and powerful water jets, making it suitable for harsh environments. The terminal protection rating of IP20 further enhances safety by preventing accidental contact with live parts.</p><p>This product complies with several international standards, including EN IEC 60947-1, EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529, EN 50013, DIN 40050-9 as well as North American standards UL 508 and CSA C22.2 No.14. These certifications attest to its quality and reliability across various global markets.</p><p>Designed to operate efficiently within an ambient temperature range of -25 to +70 degrees Celsius, this device can withstand challenging conditions without compromising performance. Its rated insulation voltage stands at a substantial 690 V while offering a rated impulse withstand voltage of up to 6 kV – both vital parameters that ensure operational integrity under transient overvoltages.</p><p>The actuator type is extended with a diameter of 22 mm which provides ease of use even when operators are wearing gloves or working in low visibility conditions. The maintained function means once pressed; the button remains engaged until manually reset – ideal for applications requiring sustained activation without continuous manual pressure.</p><p>Its contact configuration features two normally open (2NO) contacts allowing for versatile integration into control circuits where simultaneous operations are needed. The button&#39;s yellow color serves not only aesthetic purposes but also adheres to standard color coding practices for easy identification in emergency stop functions or cautionary signaling roles.</p><p>Constructed from durable plastic materials, the bezel maintains structural integrity while minimizing weight – an important factor when considering panel installations where load constraints may apply. Accommodating cutout size matches the industry-standard diameter ensuring compatibility with existing setups or new designs alike.</p><p>Included in the package are the operator itself along with a contact block and holder simplifying installation processes by providing all necessary components upfront thus reducing procurement timeframes significantly.</p>
