Miniature Flat Pack Reed Sensor MS-324

📝Description

This miniature flat pack sensor is designed for robust industrial applications, offering the convenience of M3 screw mounting capability while reliably switching moderate loads of up to 10W. Its adaptability makes it particularly suitable for environments where fine distance adjustments are necessary. Depending on the type of magnet and AT band selected, the sensor provides various activating distances, ensuring flexibility to meet specific operational requirements.

For enhanced versatility, this miniature flat pack sensor can be customized with non-standard connectors upon request, accommodating unique integration needs in diverse industrial settings. Prior to shipping, each sensor undergoes rigorous 100% testing to validate its performance across critical parameters including Operate AT, Release AT, Static Contact Resistance, and Variable Contact Resistance. This meticulous testing process ensures that every sensor meets stringent quality standards, delivering consistent and reliable performance in demanding applications.

As an omni-polar device, the sensor responds to magnetic fields from both north and south poles, offering flexibility in magnet orientation. Engineers can optimise its operation by selecting the appropriate AT band, magnet strength, and operating axis.

In specialized applications such as those requiring secure mounting and dependable switching in industrial machinery, HVAC systems, or automotive components, this sensor’s durable construction and configurable features make it an ideal choice. Its ability to withstand challenging environments while maintaining consistent performance underscores its suitability for critical electronic and mechanical applications where reliability and adaptability are paramount.
