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.

These sensors feature integrated flanges or screw holes for stable mounting on flat surfaces. Designed for rugged environments, they offer consistent performance in industrial, automotive, and automation systems.

Key switch position sensors play a critical role in ensuring secure On/Off control for industrial and robotic systems. Unlike traditional mechanical switches that often fail in harsh environments, such as those with high humidity, chemical exposure, or dust. Our Reed Technology key switches deliver a robust, noncontact solution.

Engineered for exceptional durability and reliability, these sensors minimize costly downtime and maintenance. Backed by decades of magnetic sensing expertise, this innovative design guarantees long-lasting performance in the most demanding conditions.

Reliable Magnetic Switching for High Voltage Applications

The high voltage reed switch series delivers reliable magnetic switching for applications requiring elevated voltage and current handling. Capable of switching up to 10,000 VDC and with breakdown voltages reaching 15,000 VDC, these switches are engineered for high-performance environments such as photovoltaic systems, medical equipment, and automated test systems.

Available in glass body lengths starting at 14 mm, the series includes surface mount (SMD), through-hole, and free-standing options. These reed switches can carry continuous currents up to 15 Amps and pulsed currents up to 30 Amps, making them ideal for proximity, position, motion, and end-limit sensing.

For enhanced durability and simplified integration, these switches can be packaged as high voltage reed relays. Popular relay series such as H, HE, HM, KT, SHV, LI, and BE provide a range of contact configurations and insulation resistance exceeding 10¹³ Ohms, supporting both pick-and-place automation and high-voltage isolation.

Magnetic field strength position sensors use analog Hall effect technology to measure the intensity and polarity of magnetic fields with high accuracy. These sensors provide a voltage output proportional to the magnetic field strength, making them ideal for applications such as proximity detection, current sensing, and residual magnetism measurement. Available in fixed-gain and programmable models, they support a wide range of sensitivities and response times. With options for ratiometric output and internal voltage regulation, these sensors offer flexible integration into industrial, automotive, and electronic systems.

Multipoint sensors are designed to detect fluid levels at specific, predefined points. Using multiple reed switches and floats on a single stem, these sensors can monitor up to 9 distinct levels. Ideal for applications requiring discrete level detection, such as tanks with layered liquids of varying densities, these sensors offer reliable switching, even under extreme temperatures and pressures. The LS04 and LS05 series exemplify this adaptability, supporting multiple floats and custom configurations for versatile fluid monitoring.
