📝Description
These Ultra Miniature Reed Sensors are specially crafted for precise signal switching applications, offering a distinct size advantage compared to standard SMD reed sensors. Featuring molded pre-flattened leads, these sensors ensure minimal shock absorption during SMD integration. Available in various actuating distances determined by the magnet and AT band employed, they are meticulously tested to guarantee reliable performance. Testing includes 100% verification of Operate AT, Release AT, Static Contact Resistance, and Variable Contact Resistance prior to packaging, ensuring consistent quality.
Designed as an Omni-polar device, these ultra miniature reed sensors respond equally well to north or south pole actuation, or both simultaneously. Optimal selection of the AT band, magnet strength, and operating axis allows precise control over the number of operates and releases, ensuring single-action functionality when needed. All dimensions are detailed in millimeters (mm), providing clarity for integration into diverse applications.
The compact size and robust performance make these Ultra Miniature Reed Sensors ideal for applications where space is limited yet reliability is critical. Their ability to withstand shock during assembly, coupled with comprehensive testing protocols, ensures they meet stringent performance standards in diverse environments. Whether in industrial automation, consumer electronics, or automotive systems, these sensors offer a dependable solution for efficient signal switching needs.
