<p>When it comes to selecting a reliable and robust control device for industrial applications, this non-illuminated push button stands out with its impressive features and compliance with rigorous standards. Designed for use in demanding environments such as mining, construction, and heavy industry, it is engineered to withstand tough conditions while ensuring consistent performance.</p><p>With an IP66 degree of protection, this push button offers excellent resistance against dust and powerful water jets, making it ideal for harsh outdoor or indoor settings where durability is crucial. Its compliance with standards like EN IEC 60947-5-1, EN IEC 60947-5-5, EN IEC 60073, EN IEC 60529, UL 508, and CSA C22.2 No. 14 ensures that the product meets global safety and operational requirements.</p><p>The ambient temperature range of -30 to 70 degrees Celsius highlights its capability to function effectively in extreme temperatures without compromising on performance. This feature is particularly beneficial in environments subject to fluctuating temperatures or where equipment may be exposed to severe weather conditions.</p><p>Featuring a screw connection type for secure installation and maintenance ease, the push button supports a rated insulation voltage of up to 690 V along with a rated impulse withstand voltage of 4 kV. These specifications ensure that the device can handle high electrical demands safely.</p><p>The contact configuration of 1NO (normally open) makes it suitable for various control applications where an open circuit is required until the actuator is engaged. The extended actuator type provides user-friendly operation while maintaining functionality over time.</p><p>Constructed with a metal bezel material and designed with a cutout size of 22 mm diameter matching its overall diameter specification ensures compatibility with standard panel designs. The maintained function allows the button to remain in position once pressed until manually reset—ideal for operations requiring sustained engagement without continuous pressure from operators.</p><p>A striking blue button color not only adds visibility but also aids in differentiating functions within complex control systems. This can help reduce operator errors by providing clear visual cues associated with specific actions or processes within industrial setups.</p><p>In summary, this push button combines reliability with efficiency through its well-rounded features tailored for challenging industrial environments. Its adherence to international standards further reinforces confidence in its quality and suitability across diverse applications requiring robust solutions.</p>
