<p>When it comes to reliable pushbutton solutions for industrial and commercial applications, the YW Series Mushroom Pushbutton stands out as a dependable choice. Designed with practicality and durability in mind, this pushbutton is suited for environments that demand robust performance.</p><p>The pushbutton operates at a rated voltage of 250 VAC/DC, making it versatile for various electrical systems. It features an illuminated design, enhancing visibility in low-light conditions without compromising on functionality. With dimensions of 30 mm in width, 41.4 mm in height, and 66.3 mm in depth, it offers a compact yet substantial presence suitable for numerous panel designs.</p><p>Engineered to withstand harsh conditions, the YW Series boasts an operational temperature range from -20&#176;C to 55&#176;C. Its storage temperature capability extends further from -40&#176;C to 85&#176;C, ensuring resilience during transportation and storage phases. The terminal type is screw-based for secure connections.</p><p>Safety and protection are paramount; hence the front of the device is rated IP65 while terminals are rated IP20. This degree of protection ensures resistance against dust ingress and water jets at the front side while maintaining basic protection at the terminal end.</p><p>In terms of compliance, this pushbutton meets several international standards being cULus listed, CE marked, UKCA certified, and CCC certified—providing assurance regarding its quality and safety across different regions.</p><p>For environments subject to mechanical stressors such as vibration or shock, this product excels with vibration resistance from 5-55 Hz and shock resistance up to 10 g/ms. The rated insulation voltage stands at an impressive 600 V with an insulation resistance of 100 MOhm ensuring reliability under high-stress scenarios.</p><p>The mechanical life expectancy varies depending on configuration: single contact block operations can reach up to 0.25 million cycles while double contact blocks support up to 0.1 million operations—testament to its endurance over time.</p><p>This model features a mushroom actuator type with a diameter of 40 mm providing easy operation even when wearing gloves—a common requirement in industrial settings—and has a momentary function ideal for tasks requiring temporary activation.</p><p>The contact configuration includes one normally closed (1NC) contact made from silver material known for excellent conductivity properties supporting continuous current ratings up till ten amps (10 A). While there’s no lamp included within this setup itself; should illumination be required later down line modifications can easily accommodate additional lighting needs thanks largely due cutout size also measuring exactly forty millimeters across!</p><p>Constructed using plastic bezel materials which not only contribute towards reducing overall weight but also enhance aesthetic appeal particularly where modern sleek designs desired most importantly though remains practical choice those who value longevity above all else given humidity tolerance ranging between forty-five eighty-five percent respectively make sure always ready perform regardless climate conditions encountered along way!</p>
