1.Reed Relays Reed relays use a magnetically actuated sealed reed switch to provide electrical isolation between the control coil and the switched circuit. They are small, fast, and designed for reliable routing of signals in compact equipment. Benefits Electrical isolation between coil and switched circuit Small form factor suitable for dense PCBs and tight assemblies Low coil power consumption for energy efficiency Fast actuation and release for responsive switching Hermetically sealed glass envelope protects contacts from dust and humidity Low contact resistance with stable performance over many cycles Durable in controlled environments and compatible with compact instrumentation Key attributes Function: magnetic actuation provides signal switching with no direct electrical connection between coil and contacts Compatibility: available in common contact configurations (such as SPST, SPDT, DPDT) to fit a range of routing needs; designed for standard PCB mounting Size: compact and low profile for tight spaces Material: glass encapsulated reed switches with robust contact materials; coil assembly on a durable frame Performance: fast switching, reliable cycle life, good isolation for low power signal applications Applications Test and instrumentation equipment for routing precise, low level signals Data acquisition and communications hardware for signal routing and shielding Industrial control boards and automation modules where compact signal switching is required Selection considerations Ensure coil voltage matches drive electronics Match contact form to signal type and current level Verify isolation requirements and switching speed meet system needs
