These characteristics make the (S) series particularly suitable for demanding industrial environments where EMC compliance, operational reliability, and signal integrity are paramount concerns.<\/p>\n<span class=\"cn\">RHEYFIRM\u00ae (S) 3+3\u82af\u8bbe\u8ba1\u4ee3\u8868\u4e86\u9488\u5bf9\u9ad8\u529f\u7387\u79fb\u52a8\u8bbe\u5907\u5e94\u7528\u4e2d\u56fa\u6709\u7535\u78c1\u517c\u5bb9\u6027\u6311\u6218\u7684\u7cbe\u5bc6\u5de5\u7a0b\u89e3\u51b3\u65b9\u6848\u3002\u901a\u8fc7\u5728\u7535\u7f06\u95f4\u9699\u4e2d\u5bf9\u79f0\u5206\u5e03\u4e09\u6839\u4fdd\u62a4\u63a5\u5730\u5bfc\u4f53\uff0cNexans\u76f8\u6bd4\u4f20\u7edf\u5355\u63a5\u5730\u914d\u7f6e\u5b9e\u73b0\u4e86\u7535\u78c1\u573a\u62b5\u6d88\u3001\u4f20\u9012\u963b\u6297\u964d\u4f4e\u548c\u5353\u8d8a\u7684\u5171\u6a21\u566a\u58f0\u6291\u5236\u3002\u8fd9\u4e9b\u7279\u6027\u4f7f(S)\u7cfb\u5217\u7279\u522b\u9002\u7528\u4e8eEMC\u5408\u89c4\u6027\u3001\u8fd0\u884c\u53ef\u9760\u6027\u548c\u4fe1\u53f7\u5b8c\u6574\u6027\u81f3\u5173\u91cd\u8981\u7684\u4e25\u82db\u5de5\u4e1a\u73af\u5883\u3002<\/span>\n<\/section>\n\n<div class=\"references\">\n<h3>References &#038;
