<p>When it comes to selecting a reliable and robust control device for demanding environments, this non-illuminated push button stands out as an excellent choice. Designed with industrial applications in mind, it is particularly suited for mining, construction, and heavy industry settings where durable performance is paramount.</p><p>One of the key features of this push button is its impressive degree of protection rated at IP66. This ensures that the device is well-protected against dust ingress and powerful water jets from any direction, making it ideal for harsh and challenging conditions. Compliance with standards such as 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 further testifies to its reliability and safety across various international markets.</p><p>The push button operates efficiently within a wide ambient temperature range from -30&#176;C to +70&#176;C. This adaptability ensures consistent performance in both extremely cold and hot environments which are common in many industrial applications.</p><p>With a screw connection type facilitating straightforward installation and maintenance, the device supports ease of use without compromising on security or stability. The rated insulation voltage stands at an impressive 690 V while the rated impulse withstand voltage reaches up to 4 kV—both indicators of its capability to handle high electrical demands safely.</p><p>Featuring a flush actuator type with a diameter of 22 mm, this push button offers a maintained function ensuring that once activated it stays engaged until manually reset—a critical feature for operations requiring sustained activation without constant user intervention.</p><p>The contact configuration is set at 2NC (two normally closed contacts), providing additional layers of operational safety by ensuring circuits remain closed unless deliberately opened by pressing the button itself.</p><p>Constructed with metal bezel material adds not only aesthetic appeal but also contributes significantly towards durability under tough working conditions. Its cutout size matches the standard diameter at precisely 22 mm allowing seamless integration into existing setups or new installations alike.</p><p>Finally dressed in red color signifies urgency or stop functions making it easily identifiable even from afar—an essential factor when quick response times are crucial during emergency situations prevalent within heavy industries.</p>
