<p>When it comes to selecting a reliable pushbutton for industrial and commercial applications, the YW Series Pushbutton stands out with its robust specifications and practical design. This pushbutton is engineered to meet the demands of various environments, offering both durability and functionality.</p><p>Designed with an operational voltage of 250 VAC/DC, this illuminated pushbutton ensures optimal performance across different electrical systems. The device&#39;s dimensions—30 mm in width, 41.4 mm in height, and 66.3 mm in depth—make it compact yet effective for space-conscious installations.</p><p>The YW Series Pushbutton is built to withstand challenging conditions. It operates efficiently within a temperature range of -20 to 55&#176;C and can be stored safely between -40 to 85&#176;C. Its IP65 front protection guarantees resistance against dust and low-pressure water jets from any direction, while the IP20 terminal protection ensures safe handling during installation.</p><p>Compliance with international standards is assured as the product boasts cULus listing, CE marking, UKCA certification, and CCC certification. These endorsements confirm that the pushbutton meets stringent safety and quality requirements globally.</p><p>For those concerned about mechanical resilience, this model offers impressive vibration resistance ranging from 5-55 Hz and shock resistance rated at 10 g/ms. The mechanical life spans up to 0.25 million operations for single contact blocks or up to 0.1 million operations for double contact blocks—ensuring longevity even under frequent use.</p><p>The actuator type features a mushroom design with a diameter of 40 mm—a user-friendly size that facilitates ease of operation in emergency situations or regular usage scenarios where quick access is crucial.</p><p>Its contact configuration includes one normally open (1NO) contact block which supports a maintained function ensuring the circuit remains active until manually reset—a valuable feature in many control applications.</p><p>This red lamp-coloured unit does not include an internal lamp but supports external illumination options if needed by your setup requirements. With an insulation resistance of 100 MOhm and rated continuous current capacity at 10 A, it promises reliable electrical performance over time.</p><p>Installation is straightforward thanks to its screw terminal type connection method while fitting into standard cutout sizes also measuring at a convenient diameter of 40 mm allows seamless integration into existing panels or new projects alike without hassle regarding compatibility issues often encountered otherwise elsewhere unnecessarily complicating things further unnecessarily so instead thankfully here they do not apply whatsoever fortunately enough indeed!</p><p>Overall humidity tolerance ranges between comfortable levels from around mid-forties percent upwards reaching eighty-five percent maximum thus accommodating varied environmental conditions typically encountered across diverse settings ranging widely geographically speaking quite broadly indeed!</p><p>In conclusion: The YW Series Pushbutton combines technical excellence alongside practical usability making it ideal choice suited perfectly well especially considering demanding roles requiring high reliability standards consistently met reliably every time!</p>
