<p>When selecting a pushbutton for industrial and commercial applications, understanding the technical specifications is crucial. This particular pushbutton offers robust features tailored to meet demanding environments.</p><p>With a rated voltage of 24 VAC/DC and frequency compatibility at both 50 and 60 Hz, this pushbutton is versatile in its electrical application. The illumination feature enhances visibility with an incandescent lamp that emits a blue hue, making it suitable for diverse operational settings.</p><p>The device operates efficiently within a temperature range of -25 to 60 degrees Celsius, ensuring reliability across various climates. Its construction includes a flush actuator type housed in a round metal bezel, providing durability and resistance to wear over time.</p><p>Safety and protection are well-addressed with an IP65 degree of protection on the front side, safeguarding against dust ingress and water jets. Meanwhile, the terminal is rated at IP20, offering basic protection against finger access. Compliance with UL listing, CE marking, ULKA approval, and CSA certification underscores its adherence to international safety standards.</p><p>The HW series pushbutton boasts an impressive mechanical life expectancy of up to 5 million operations. This longevity can significantly reduce maintenance costs over time while maintaining consistent performance.</p><p>For electrical insulation needs, it offers a rated insulation voltage of 600 V coupled with an insulation resistance of 100 MOhm—ensuring safe operation under high-voltage conditions. The contact configuration is designed as normally open (1NO) using silver contacts for reliable conductivity.</p><p>Installation is straightforward thanks to its screw terminal type and standard cutout size of 22 mm diameter—a common dimension that facilitates easy integration into existing systems or control panels.</p><p>A momentary function characterizes this button&#39;s operation mode; it remains active only while being pressed—ideal for applications requiring temporary activation like machinery start-stop controls or signal initiation tasks.</p><p>Additionally, the illumination circuit operates on full voltage which simplifies wiring requirements by eliminating the need for additional transformers or resistors often needed in low-voltage circuits.</p><p>In summary, this pushbutton combines functionality with resilience through its thoughtful design elements such as material choice and protective measures—all contributing towards effective usage in industrial environments where reliability is paramount.</p>
