Reliability: Improving performance, reducing wear, custom features

It’s no secret: available in hundreds of sizes and shapes, crucial in dozens of industries, Standex Electronics reed switches can outperform the competition. Moreover, they’re equipped to survive billions of operations in even the most extreme areas. It continues to grow in popularity as the basis in relays and sensors for switching, detecting, and counting applications across the globe. Why wouldn’t you want Standex’s advanced reed switches for your own products?

As a technology, the Reed Switch is unique. First, at its core is a glass-to-metal hermetic seal, which encloses the two ferromagnetic reeds in a glass envelope and protects them from the environment. And, as a result of this simple design, the Reed Switch can operate in the harshest spaces. In addition, it requires no direct contact when part of a reed sensor.

Second, Standex Electronics reed switches are rigorously tested to ensure the quality of our manufacturing processes and resulting products. Moreover, we can also customize any switch to your own design! Custom designs include value-add services such as PCB assembly, epoxy sealing, conformal coating, and wire termination.

As new, improved designs create the demand for more sensing needs, it’s time for a switching solution that makes sense—for product longevity, for power efficiency, and for your unique needs!

  • Drop-out (the points where the contacts open)
  • Hysteresis
  • Contact resistance
  • Dynamic contact resistance
  • Switching voltage
  • Switching current
  • Carry current
  • Stray capacitance
  • Common mode voltage
  • Switching wattage

Where reed switches reside

Due to their extensive features, the base component of the below product is the reed switch.

Industry applications

Reed switch sensors and relays are fit in any device that needs to detect movement, rotation, and liquid level.  Standex Electronics reed switch products serve in Automotive, Aviation, Military, Medical, and Test Equipment. More importantly today’s emerging markets are calling upon reed switches as a low power solution in Electric Vehicles, LED, Solar and Photovoltaics.

Conclusion

In summary, compared to mechanical switches, the reed switch has many advantages. First, it requires no switching load while effectively sensing from up to 44 mm away. In addition, you can adjust the switch hysteresis to fit your specific design needs. Conversely, working with mechanical switches, you’re limited to differential travel. Finally, with no wearing parts, the reed switch can also outlast mechanical switches. And, last an unusually long life in the billions of operations.
