UW-09-628-W(S)

Overview

The Floyd Bell Inc. UW-09-628-W(S) is a miniature reed switch designed for low-power signal switching applications. This component utilizes a hermetically sealed glass envelope containing ferrous reed contacts that close upon the application of an external magnetic field. The device is characterized by its compact physical dimensions and reliable mechanical operation, suitable for integration into space-constrained electronic assemblies requiring non-contact switching capabilities.

Feature Summary

• Hermetically sealed glass construction ensures long-term environmental stability and contact protection against moisture and contaminants.
• Magnetic actuation mechanism provides electrical isolation between the control field and the switched circuit without physical wear.

Applications

• Security system sensors
• Reed relay driver circuits
• Low-power signal monitoring

Procurement Notes

Verify the specific suffix designation to confirm lead frame material and terminal configuration. Ensure the selected variant matches the required operating voltage and current ratings for the target circuit. Confirm compliance with relevant safety standards before finalizing procurement specifications.

Selection Notes

Evaluate the coil drive requirements to ensure sufficient magnetomotive force activates the reeds reliably. Consider the package style compatibility with the printed circuit board layout. Assess the environmental conditions to determine if the standard glass seal meets the operational temperature range requirements.

Part Context

This component belongs to the family of electromechanical reed switches manufactured by Floyd Bell Inc. These devices are widely utilized in industrial and consumer electronics where reliable, maintenance-free switching is required. The product line emphasizes durability and consistent performance across various mounting orientations.

Replacement Considerations

Cross-reference pinout configurations and envelope dimensions when evaluating alternative suppliers. Verify that substitute components meet the same electrical isolation and contact resistance specifications.
