Reed Relays Function Reed relays are compact electro mechanical switches that use a sealed glass reed contact actuated by a coil. They provide electrical isolation between the coil and the switched circuit while delivering reliable signal level switching with fast response. Compatibility Designed for standard PCB mounting and integration with common instrumentation and control electronics. Suitable for typical signal level switching and available in configurations that support precise, low noise operations. Size Compact footprints with slim profiles to fit dense PCB layouts and multi channel assemblies without compromising performance. Material Glass sealed reed switches with metal reeds, encapsulated in a protective epoxy housing for durability in typical environments. Performance Low contact resistance, fast switching, and strong coil to contact isolation. Consistent operation across a range of temperatures with long mechanical and electrical life under normal use. Use scenarios 1) Signal routing in data acquisition and test equipment. 2) Switching sensor or low level control lines in automation systems. 3) Lab bench instrumentation and educational electronics projects. Notes Operate within applicable coil drive specifications and maintain separation between coil and contact circuits to preserve isolation. Use appropriate layout practices to minimize external magnetic interference.
