Ultraminiature reed relays are engineered for high-density, low-profile applications where space and performance are critical. With package heights as low as 3.4 mm and footprints under 8 mm, these instrumentation-grade relays are among the smallest in the industry. Ideal for tightly stacked matrices and compact PCB layouts, they offer high insulation resistance, low contact resistance, and reliable switching for billions of operations.
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.
Reliable Switching in a Small Footprint
The miniature reed switch series features compact, power-efficient magnetic switches with glass body lengths ranging from 9 to 14 mm. Designed for precision and versatility, these switches operate with no power consumption in their normally open state, making them ideal for energy-sensitive applications.
Available in a wide range of switching characteristics, including close differential, high current, mercury wetted, high-performance, and SPDT (changeover) configurations, this series supports diverse design requirements across industries. Their small footprint makes them especially valuable in miniaturized systems such as semiconductor testing equipment and medical devices, while also serving critical roles in telecommunications, security, automotive, appliances, and industrial automation.

Continuous level sensors provide real-time monitoring across the entire height of a fluid container. These sensors use magnetic reed switches mounted along a PCB, combined with resistors to generate discreet voltage outputs. As a magnetic float moves along the sensor stem, it activates multiple reed switches, enabling precise and uninterrupted tracking of fluid levels. Advanced models like the CLS and HLS series incorporate capacitive or Hall effect technologies for high-resolution, programmable outputs in harsh environments.
