Safety relays with muting function are specialized industrial components designed to enhance machine safety, commonly used in automation and manufacturing sectors. These relays are produced by various global companies, such as Siemens (Germany), Pilz (Germany), and Omron (Japan). They serve industries like automotive, packaging, and robotics by ensuring safe equipment operation during muting phases (e.g., when materials pass through light curtains). Key products include configurable safety relays, modular muting controllers, and integrated solutions compliant with ISO 13849 and IEC 62061 standards.
