<p>The YW Series illuminated indicator is a robust and reliable choice for industrial and commercial applications, designed to meet demanding environmental conditions. With a rated voltage of 100/110 VAC and operational at frequencies of 50/60 Hz, this unit provides flexibility across various electrical systems.</p><p>One of the standout features is its wide operational temperature range from -20&#176;C to 55&#176;C, ensuring performance in diverse climates. Additionally, it can withstand ambient temperatures ranging from -45&#176;C to 80&#176;C, making it suitable for both cold storage facilities and high-temperature environments.</p><p>This indicator uses a built-in LED lamp that emits a clear red light, enhancing visibility even in low-light conditions. The use of LEDs not only ensures long-lasting illumination but also contributes to energy efficiency—a crucial factor for businesses aiming to reduce energy consumption.</p><p>The unit&#39;s shock resistance capability supports up to 100 ms impacts, offering durability in environments where mechanical vibrations or shocks are common. This resilience is complemented by its IP20/IP65 degree of pollution protection ratings. While IP20 offers basic protection against solid objects over 12mm and no water ingress protection, the IP65 rating ensures complete dust-tightness and resistance against water jets—ideal for areas where exposure to moisture or particulates is expected.</p><p>Installation is straightforward with an M3.5 screw terminal type and requires a mounting hole diameter of 29.8 mm. This standard size facilitates easy integration into existing panels or systems without needing custom modifications. </p><p>Insulation resistance stands at an impressive 100 MOhm, providing assurance against electrical leakage and enhancing safety during operation. The device operates optimally within humidity levels of 45-85%, maintaining functionality in varying atmospheric conditions.</p><p>The cover color matches the lamp color—red—which can be useful for signaling specific statuses or alerts within control systems.</p><p>Overall, this product balances functionality with durability through thoughtful design elements tailored for challenging industrial settings while maintaining ease-of-use during installation and operation phases.</p>
