Crucial for the development of the double NC contact switch was the standard ISO 13849-1, which also forms the basis of the new Machinery Directive of the European Union. To meet the safety requirements of the directive , it will become necessary that the safety-related parts of control systems for machines and plant are designed to be fully redundant. Features: - Positive opening operation : Reliable interruption of both circuits even after contact welding, in compliance with IEC 60947-5-1, Annex K - Double NC contacts: Safety switch featuring two galvanically isolated circuits in one housing. Used for applications complying with ISO 13849-1. - Precision switch: High switching accuracy and resistance to shock and vibration - Wiping contacts : Continuous low contact resistance ensures high contact reliability over the entire design life of the Switch - Sealed to: IP40 in accordance with IEC 60529 - Contact material: Silver or gold-plated silver
