Reed Relays What this product does Electrically isolates and switches low-level signals using a magnetically actuated reed contact sealed in glass. Provides reliable on/off switching for analog and digital circuits where insulation and low leakage are important. Key benefits — why you need it Clean signal switching: Hermetically sealed contacts reduce contamination and contact resistance, improving signal integrity. Long-term reliability: Simple mechanical contact design and glass sealing deliver consistent operation over many cycles. Low-power control options: Small coil energy requirement makes integration with microcontrollers and low-voltage driver circuits straightforward. Compact form factor: Small package sizes save board space and simplify layout in dense assemblies. Electrical isolation: Magnetic actuation separates control and switched circuits, improving safety and noise immunity. Important attributes Function: Magnetically actuated switch for opening and closing circuits; available for single-pole and multi-pole requirements. Compatibility: Works with low-voltage and low-current signal circuits, instrumentation, communications equipment, and logic-level control; compatible with common PCB mounting and through-hole layouts. Size and mounting: Compact, space-saving packages suitable for board-level or modular assemblies. Materials and construction: Glass-sealed contacts and metallic reeds provide hermetic protection against contaminants and moisture. Performance: Low contact resistance, low leakage when open, fast switching response, and stable operation over a wide range of cycles and environmental conditions. Practical use scenarios Test and measurement: Switch sensor outputs or signal lines in automated test equipment where low contact resistance and repeatability are required. Telecommunications and networking: Route or isolate analog or digital signals on line cards and modular subsystems that demand compact, reliable switches. Embedded and industrial control: Use as a low-power relay driven by microcontrollers to isolate control logic from external sensors or actuators. Why choose reed relays for your design They provide a balance of small size, dependable contact performance, and electrical isolation that is hard to match with solid-state or larger electromechanical relays. Their sealed construction reduces maintenance and improves longevity in applications where clean, repeatable switching matters.
