<p>When selecting components for industrial and commercial applications, understanding the specifications is crucial to ensure compatibility with your technical requirements. The product under discussion features a robust design tailored for demanding environments.</p><p>This non-illuminated button stands out with its substantial 40 mm diameter, making it suitable for applications where visibility and accessibility are key. The black button color provides a sleek appearance while ensuring it remains unobtrusive in various settings.</p><p>Durability is a significant factor in selecting control components, and this product delivers with an IP66 degree of protection on the front side. This rating ensures that the device is dust-tight and protected against powerful water jets, making it ideal for outdoor or harsh indoor environments where exposure to moisture or dust is a concern. Meanwhile, the terminal has an IP20 rating, indicating basic protection against finger access but should be considered when planning installation locations.</p><p>The contact configuration includes one normally open (1NO) contact. This setup is commonly used in circuits requiring an open state until activated by pressing the button, which then closes the circuit to allow current flow—ideal for start-stop operations or signaling tasks within automated systems.</p><p>The twist release method adds another layer of functionality by providing a secure way to reset or deactivate processes manually. This feature can be particularly beneficial in emergency stop scenarios where inadvertent reactivation needs prevention without deliberate user action.</p><p>Constructed with a plastic bezel material, this product balances durability with weight considerations—important factors when integrating into larger panels or machinery setups. The cutout size matches the 40 mm diameter of the button itself, simplifying installation by maintaining consistent dimensions across all components involved.</p><p>In summary, this product offers reliable performance through its combination of protective ratings and practical design elements such as contact configuration and release mechanism. It serves well in both industrial automation contexts and commercial building systems where resilience and straightforward operation are paramount considerations.</p>
