{"id":783,"count":6,"description":"Safety relays monitor safety functions such as emergency stops, safety gates and light curtains and safely stop the machine when a fault is detected. SCN supplies safety relays from Wieland Electric, including the SNZ4052K, SNE4004K, SNO4003K, SNO4062K and SNO4063K, as well as the SAMOS modular safety controller for machines with several safety functions. They are used in emergency stop circuits, safety gate and door monitoring, light curtains, two-hand control and general machine safety. Our engineers help you choose the right safety function, number of safety outputs, supply voltage and reset mode for your application.","link":"https:\/\/scn.eu\/en\/product-category\/products\/components\/safety-relays\/","name":"Safety relays","slug":"safety-relays","taxonomy":"product_cat","parent":10631,"meta":[],"menu_order":0,"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Safety Relays \u2013 E-Stop, Safety Gate &amp; Light Curtain | SCN<\/title>\n<meta name=\"description\" content=\"Safety relays and modular safety controllers for emergency stop, safety gates and light curtains.
