{"id":656,"count":191,"description":"Relays and sockets for switching signals and loads reliably in demanding aerospace and defence equipment. SCN supplies mainly hermetically sealed military and aerospace relays from Leach, including the KCA, M320, F492, FLSH402, S215 and D series, together with matching sockets and accessories such as the 10106 relay isolation pad for PCB mounting. The range covers relays and sockets for aero and defence applications, rail vehicles and other harsh environments where components must withstand tough operating conditions. Our engineers help you choose the right contact configuration, coil voltage, switching load and mounting style for your application.","link":"https:\/\/scn.eu\/en\/product-category\/products\/components\/relays-and-sockets\/","name":"Relays and sockets","slug":"relays-and-sockets","taxonomy":"product_cat","parent":10631,"meta":{"scn_kategori_text":""},"menu_order":0,"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Relays and Sockets \u2013 Hermetic, Aero &amp; Defence | SCN<\/title>\n<meta name=\"description\" content=\"Hermetically sealed relays and matching sockets for aerospace, defence and rail.
