Reed Relays
Products
General purpose reed relays offer reliable and flexible switching solutions for a wide range of applications across industries such as automated test equipment (ATE), medical devices, industrial systems, and telecommunications. Built around high-quality reed switches capable of billions of operations (load dependent), these relays deliver consistent performance in both low and moderate power environments.
Available in multiple sizes and configurations, including single and multi-switch designs, these relays support SPST, SPDT, and latching contact forms. Popular models feature dual-in-line (DIL/DIP) pin-outs, low-profile options, and high insulation resistance versions up to 10¹³ ohms, making them suitable for compact PCB layouts and high-isolation requirements. Whether you need a single relay or a multi-channel solution, these relays provide dependable switching in versatile formats.
High density matrix reed relays are designed for ultra-compact, high-channel-count applications where space efficiency and performance are critical. With footprints as small as 4.35 × 4.35 mm, these relays enable dense relay arrays, up to 1000 relays on a 12” board, ideal for IC wafer testing, functional PCB test systems, and data acquisition platforms. Featuring low power consumption, fast switching speeds, and optional shielding configurations, they offer reliable performance in demanding environments. Their modular design supports vertical and horizontal stacking, making them a versatile solution for high-density signal routing and matrix switching.
High frequency reed relays are engineered for precision signal switching from DC up to 8 GHz, making them ideal for RF, microwave, and high-speed digital applications. These relays feature ultra-short signal paths and internal coaxial shielding with consistent 50 Ohm impedance, ensuring minimal insertion loss and excellent signal integrity. With rise times under 40 picoseconds and low contact resistance, they support fast pulse switching and high isolation in compact designs. Available in surface-mount packages with advanced shielding, they are optimized for automated test equipment, wireless systems, and high-frequency PCB layouts.
High insulation resistance reed relays are designed for ultra-low leakage current performance, making them ideal for precision applications where signal integrity and isolation are critical. Engineered with specialized materials, extended creepage distances, and optimized internal geometry, these relays achieve insulation resistance levels up to 100 tera-ohms (TΩ) and in some cases, even 1,000 TΩ resulting in leakage currents in the picoampere range or lower.
These relays are available in configurations that support switching voltages up to 1,000 VDC and breakdown voltages up to 4,500 VDC, with custom options reaching 10,000 VDC switching and 15,000 VDC breakdown. Their high isolation and dielectric strength make them ideal for automated test equipment (ATE), semiconductor testing, and precision measurement systems where even the smallest leakage can impact results.
Compact, reliable, and built for demanding environments, High Insulation Resistance reed relays offer unmatched performance in high-voltage, low-leakage applications.
High voltage and high-power reed relays are engineered for demanding applications that require reliable switching of elevated voltages and currents. These relays support switching voltages up to 1,000 VDC in compact packages, making them ideal for use in automotive systems, solar energy, EV battery management, medical devices, and automated test equipment (ATE).
For extreme voltage requirements, specialized models are available that switch up to 10,000 VDC, with breakdown voltage ratings reaching 15,000 VDC. These high-voltage relays are trusted in critical medical technologies such as portable defibrillators and electrosurgical generators, where insulation integrity and safety are paramount.
Designed with robust isolation, high dielectric strength, and low contact resistance, these relays offer long operational life and stable performance in high-energy environments. Their compact form factors and versatile configurations make them suitable for both high-voltage isolation and high-current control across a wide range of industries.
Intrinsically safe reed relays and optocouplers are engineered for use in hazardous environments where ignition prevention is critical. Certified to ATEX standards and tested to ensure they do not become ignition sources, even in the presence of short circuits or adjacent component failures—these components are ideal for applications in explosive atmospheres such as mining, chemical processing, refineries, and power stations.
Designed to meet EN50020 safety standards, these relays and optocouplers feature tightly controlled air and creepage paths, high dielectric strength, and low-voltage coil inputs. With a maximum peak voltage of 375 V across input and output, and isolation distances up to 10 mm, they ensure safe operation under overload conditions. The Comparative Tracking Index (CTI) of the plastics used exceeds 175, and internal potting compounds provide additional insulation for long-term reliability.
Low thermal reed relays are designed to switch microvolt-level signals without introducing thermal offsets or signal distortion. Ideal for use in transducers, high-end multimeters, thermocouple switching, and data acquisition systems, these relays ensure accurate signal integrity in temperature measurement and logging applications. Their low offset voltage performance makes them a superior alternative to semiconductor relays in precision environments.
Reed Relay Modules integrate multiple high-performance reed relays into compact, ready-to-use packages for efficient signal switching in space-constrained designs. Available in 8-channel configurations, these modules simplify circuit design by combining switching functionality with integrated driver electronics and advanced packaging.
