Reliable Break-Before-Make Switching with Form C Reed Technology

Changeover reed switches, also known as Form C or SPDT (Single Pole Double Throw) switches, feature three contact leads and operate with a break-before-make switching sequence. This means one contact disconnects before the other connects, ensuring clean signal transitions and reducing the risk of short circuits.

Changeover reed switches are ideal for applications requiring reliable switching between two circuits, such as signal routing, sensor feedback, and control logic.

These switches can be integrated into standard sensors and reed relay assemblies, and custom configurations are available to meet specific design requirements.

The brand new Linea2 family takes your system to the new level with impressive performance and value, offering 5x the bandwidth of our Linea family with a 5GigE interface. The Linea2 line scan cameras are powered by our very own Teledyne quadlinear sensor, extending detection capability using RGB + NIR multispectral imaging technology.

• Measuring device to detect the twist/lay/pitch length of sheathed cables
• Measurements according to the standards LV212 und LV122
• The twist length of the sample is measured without removing the sheath → this ensures a precise measurement
• Traditional methods manipulate the sample (cable stripping or unwinding of conductors) → a precise measurement is not possible anymore
• Via a PC connection, the measuring results can directly be exported
• Fully automatic: By clicking one button, the measuring sensor automatically moves along the sample

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.

Non-ATEX certified optocouplers provide effective electrical isolation between input and output circuits using light-based signal transmission. Ideal for environments where explosive atmosphere certification is not required, these components offer dependable performance in signal switching, noise reduction, and circuit protection across a wide range of standard applications.

ATEX and IECEx certified optocouplers are designed for use in intrinsically safe circuits within hazardous environments. These solid-state devices provide galvanic isolation and signal transmission without becoming ignition sources, even under fault conditions. Ideal for industries such as oil & gas, mining, and energy, they offer high isolation resistance, fast switching, and long operational life in compact, rugged packages.

The high frequency reed switch series is engineered for precision switching in RF and high-speed digital applications. These switches are optimized to handle signals from DC up to 7 GHz, making them ideal for use in telecommunications, computing, and advanced test equipment.

With nickel/iron leads offering high magnetic permeability, these reed switches deliver exceptional linearity across a broad frequency spectrum. Their compact form factor allows for high-density PCB mounting, and internal shielding ensures minimal electromagnetic interference, even in tightly stacked configurations.

These switches are commonly integrated into high-frequency reed relays for enhanced durability and performance.

Ultra-Compact Reed Switches for Precision Electronics

The ultraminiature reed switch series offers some of the smallest magnetic switching solutions available, with glass body lengths starting at just 3.95 mm. These switches are engineered for precision and reliability in space-constrained environments, making them ideal for miniaturized electronics and high-density circuit designs.

Despite their compact size, these switches maintain strong electrical performance thanks to advanced contact materials and hermetically sealed construction. Their flat lead design supports automated assembly processes such as surface mounting and tape-and-reel packaging, enabling efficient integration into high-volume production lines.

Commonly used in semiconductor testing, medical devices, telecommunications, security systems, and automotive electronics, these switches provide dependable magnetic actuation in applications where size, sensitivity, and durability are critical.

Cylindrical proximity sensors are housed in round enclosures for easy mounting in tight or standardized spaces. Available with Reed or Hall effect technology, they provide reliable detection of magnetic or metallic targets.
