Description

<p>This robust accessory is designed to seamlessly integrate with pilot devices, catering to the demanding needs of industrial and commercial applications. Built for reliability and efficiency, it operates at a rated voltage of 690 VAC/VDC and supports frequencies of 50/60 Hz, making it versatile for various electrical environments.</p><p>With dimensions measuring 20 mm in width, 44 mm in height, and 28 mm in depth, this compact component ensures easy integration into tight spaces without compromising on functionality. The non-illuminated design focuses on practicality and straightforward operation.</p><p>The device features a screw terminal type connection with a tightening torque of 1 N-m, ensuring secure connections that withstand operational stresses. Its IP20 degree of protection indicates suitability for indoor use where protection against solid objects over 12 mm is required.</p><p>Weighing just 0.04 kg, this lightweight accessory does not add unnecessary bulk to your setup. It is engineered to operate efficiently within an ambient temperature range from -25&amp;#176;C to +70&amp;#176;C while being capable of storage in conditions as extreme as -40&amp;#176;C to +85&amp;#176;C.</p><p>The rear mounting type offers straightforward installation options while maintaining accessibility for maintenance tasks. With a rated insulation voltage also at 690 V and an impressive rated impulse withstand voltage of up to 6 kV, this product ensures safety under transient overvoltage conditions.</p><p>Its contact configuration includes both normally open (NO) and normally closed (NC) contacts (1NO+1NC), providing flexibility in control circuit designs. The rated operational current capacities are diverse: accommodating currents of 0.55 A, 5 A, and up to a maximum of 6 A across different applications.</p><p>Moreover, the connecting capacity accommodates flexible wires with ferrules or insulated ferrules ranging from single or double strands between 0.75 sq-mm to 2.5 sq-mm as well as solid wires within the same range—offering extensive compatibility with various wiring standards.</p><p>Power loss is minimized at just 5 W during operation which contributes positively towards energy efficiency goals while maintaining performance integrity over time. Additionally wire stripping length required stands at only about eight millimeters simplifying preparation processes before connection assembly further enhancing ease-of-use factor overall experience when deploying these units field settings alike professional workshops environments everywhere they’re needed most today’s fast-paced world modern industry demands ever more sophisticated solutions meet challenges head-on effectively every step way forward!</p>
