Advantages of our reed contacts

Reed switches offer technical advantages when integrating magnetically actuated switching functions into compact electronic assemblies. Their hermetically sealed contact mechanism, precise magnetic actuation, and low power consumption when using a permanent magnet enable reliable switching. Reed switches demonstrate their strengths particularly in systems that require mechanically non-contact actuation.

The technical advantages of our reed switches in detail:

No external power supply is required for contact actuation when using a permanent magnet
Hermetically sealed contacts to protect the contact surfaces from external environmental influences
Contactless switching with no mechanical actuating elements outside the glass capsule
High magnetic sensitivity for precise responses due to specified pickup and release values

These characteristics make our reed switches ideal for safety-critical applications in automation technology, medical technology, and industrial sensor, control, and monitoring systems. Our reed switches are designed based on the electrical load, the magnetic drive, and the intended environmental conditions. Depending on the series, operating temperatures ranging from -40 to +130 °C or -40 to +150 °C are specified.
