RCS3E-6V

Overview

The RCS3E-6V is a reed switch manufactured by R-K Electronics, Inc. This component operates based on the closure of contacts within a glass envelope when exposed to an external magnetic field. It is designed for applications requiring reliable switching with minimal power consumption. The device typically features silver alloy contacts and is sealed in a nitrogen atmosphere to ensure longevity and stable electrical performance under various environmental conditions.

Feature Summary

• Hermetically sealed glass construction protects internal contacts from environmental contaminants.
• Low actuation force allows operation with small or weak magnets.
• Fast response time ensures quick contact closure upon magnetic field application.

Applications

• Security system sensors
• Door and window position detection
• Liquid level sensing

Procurement Notes

Verify the specific contact configuration (SPST-NO) and coil voltage requirements against your circuit design before ordering. Confirm that the package style matches your PCB layout constraints. Ensure the operating temperature range aligns with your intended environment. Cross-reference the manufacturer's datasheet for precise mechanical dimensions and electrical ratings to guarantee compatibility.

Selection Notes

Choose this model if your application requires a compact, hermetically sealed switch with low power consumption. Consider the maximum switching voltage and current ratings to ensure they exceed your circuit's peak values. Evaluate the need for shock and vibration resistance, as reed switches are sensitive to mechanical stress. Verify the magnetic sensitivity requirements to select the appropriate magnet strength for reliable actuation.

Part Context

R-K Electronics specializes in precision electromechanical components, including reed switches and relays. The RCS series is part of their standard lineup of hermetically sealed devices known for reliability. These components are widely used in industrial and consumer electronics where long-term stability and low maintenance are critical. The brand emphasizes quality control in the sealing process to prevent contact degradation over time.

Replacement Considerations

Check pinout compatibility and overall dimensions before substituting. Ensure the replacement part has equal or higher voltage and current ratings. Verify that the magnetic sensitivity is sufficient for your existing magnet assembly. Consult the manufacturer's cross-reference guide for officially confirmed equivalent part numbers.
