UB-09-628-S(S)

Overview

The Floyd Bell UB-09-628-S(S) is a miniature reed switch designed for low-power signal switching applications. It features a hermetically sealed glass envelope containing ferromagnetic contacts that close upon exposure to an external magnetic field. The component operates with minimal actuation force and provides reliable isolation in open states. Its compact form factor allows integration into space-constrained electronic assemblies requiring non-contact sensing or switching functionality.

Feature Summary

• Hermetically sealed glass construction ensures long-term environmental stability
• Magnetic field activation enables contact closure without mechanical wear
• Compact miniature package facilitates dense circuit board layouts

Applications

• Security system door and window sensors
• Liquid level detection in containers
• Position sensing in industrial automation

Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm terminal configuration and sealing integrity. Ensure compatibility with operating voltage and current ratings specified in the official datasheet for the intended circuit environment.

Selection Notes

Evaluate the required make/break cycle and coil drive characteristics against the switch's electrical limits. Confirm that the magnetic actuator strength aligns with the switch's pull-in specifications for reliable operation within the target assembly geometry.

Part Context

This component belongs to the family of magnetically operated switches manufactured by Floyd Bell Inc. These devices are engineered for durability in environments where physical contact switching is impractical or undesirable due to arcing or wear concerns.

Replacement Considerations

Consult official substitution guides for equivalent reed switches from other manufacturers. Verify pinout compatibility and magnetic sensitivity requirements before integrating alternative components.
