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.

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.

• Combine up to 16 SPDT or 8 multiport, high-performance relays in a 2U footprint
• Latching/Terminated options (EX7204L)
• LXI/LAN and USB command and control options
• Embedded web interface provides interactive utility to monitor and control relays from anywhere in the world
• Flexible API supports IVI and Linux development environments minimizing software investment
• LXI trigger event implementation provides seamless test synchronization with external devices
• Store up to 128 relay configurations for quick recall, including automatic power-up state

High Power Magnetic Switching for Demanding Applications

The high-power reed switch series offers robust magnetic switching solutions capable of handling up to 120 W and voltages as high as 1,000 VDC. Designed for demanding applications, these reed switches are available in various sizes starting from 14 mm, including surface mount and through-hole options for flexible integration.

These switches are ideal for proximity, position, motion, and end-limit sensing, and can also be packaged into high power reed relays for enhanced durability and simplified PCB mounting. Relay packaging supports both pick-and-place automation and high insulation resistance, with some models exceeding 10¹³ Ohms.

Popular series such as KT, SHV, LI, and BE offer a range of contact configurations, including SPST, SPDT, and multi-switch designs. Whether used in automotive systems or test and measurement equipment, these high-power reed switches deliver reliable performance where high voltage and current demands are critical.

Custom solutions are also available to meet specific design requirements.
