Reed Relays - Function and isolation Reed relays use a glass sealed reed switch actuated by a magnetic coil to switch circuits. They provide galvanic isolation between the coil and the switched circuit, helping protect sensitive electronics. - Key benefits - Fast switching with minimal contact bounce for reliable signal paths - Low coil power requirements simplify driver design - Compact form factors that fit in dense PCB layouts - Glass envelope and durable contact materials resist contamination and extend usable life under normal loads - High isolation between coil and contacts reduces interference and cross talk - Availability in multiple coil voltages and contact configurations to fit different applications - Sealed construction supports operation in challenging environments and across a broad temperature range - Attributes - Function Switches signals with magnetic actuation while keeping coil and contact circuits electrically separate - Compatibility Available in standard PCB mounting formats with a range of coil voltages and contact configurations to suit common systems - Size Compact and space saving, suitable for tight enclosure designs - Material Glass encapsulated reeds with durable contact materials for long life and stable performance - Performance Fast response times, low leakage, low contact resistance, and dependable operation across typical loads - Use scenarios - Scenario 1 In data acquisition and test equipment, to route measurement signals while isolating the measurement path from control electronics - Scenario 2 In telecom or instrumentation gear, to quickly switch control lines with low noise and minimal interference - Scenario 3 In industrial automation and sensor interfaces, to isolate sensitive control circuits from higher power components while switching low to moderate level signals - Selection guidance Choose a model with the appropriate coil voltage, contact configuration and load compatibility for your system to ensure reliable operation and longevity
