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.
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.
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.
Optimized for high-speed signal transmission and minimal signal distortion, these relays feature low off-state capacitance, making them ideal for RF, telecom, and precision measurement applications.
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.
These sensors detect the presence or movement of a magnet, enabling precise position or proximity monitoring. Available in Reed or Hall effect versions, they are used in medical, industrial, and consumer devices.
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.
Magnetic Float NBR or Nitrile Butadiene Rubber floats have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Magnetic Float PA or Polyamide floats are made of nylon, have a very high strength-to-weight ratio making them shock and abrasion resistant, enduring a pressure of 5 bar (73 PSI or 0.5 MPa). Magnetic Float PP (polypropylene) are rugged, highly resistant to many chemical solvents, bases and acids and have a water absorption of only 0.1%. V2A Floats are made of rust-proof stainless steel and are resistant to high temperatures making them ideal for the Food & Beverage industry among others.
Metal detection position sensors are designed to detect the presence or movement of ferrous materials such as steel bolts, gears, or plates. Available in reed switch or Hall effect configurations, these sensors offer flexible solutions for proximity and position sensing. Reed-based sensors provide simple, low-power operation, while Hall effect versions offer dynamic, solid-state performance with zero-speed detection and enhanced durability. Ideal for industrial automation, safety systems, and heavy equipment, these sensors are available in various mounting styles and electrical outputs to suit diverse application needs.
Metal detection sensors identify the presence of steel or other ferrous materials. They are used in automation, safety, and machinery applications where reliable detection of metal components is essential.
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.
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.
