Reed Relays What they are Compact, hermetically sealed electromagnetic switches. A glass envelope houses two ferromagnetic reeds that touch to complete a circuit when the coil is energized. Configurations include normally open, normally closed, and changeover. Key benefits Fast switching for precise signal routing isolation between coil and contact circuits Low contact resistance and minimal leakage in the switched path Small form factor suitable for space constrained assemblies Low coil power for efficient operation Robust, reliable performance in instrumentation and control environments Key attributes Function: electromechanical switch for low to medium level signals Compatibility: designed for integration with standard control electronics and PCBs Size: compact footprint optimized for dense layouts Material: glass envelope with sealed reed contacts and coil assembly Performance: rapid response, stable switching, good isolation, long operational life Configurations Available in normally open, normally closed, and changeover options to suit different circuit needs Use scenarios 1) Signal routing in test and measurement equipment to isolate the measurement path from the control electronics while switching lowlevel signals 2) Data acquisition systems requiring fast, repeatable switching with minimal interference to the signal being measured 3) Control panels and automation circuits needing galvanic isolation between controllers and loads in compact enclosures Notes Match coil drive to the relay to ensure reliable operation. Suitable for integration into instrumentation and control systems where compact size and isolation are priorities
