📝 Description
The standard size reed sensor, R2, is specifically engineered to handle moderate currents and feature an SMD pitch slightly wider than our miniature SMD reed sensors. Their design includes molded, pre-flattened leads to prevent shock during SMD assembly. The sensors offer various activating distances depending on the magnet and AT band utilized.
Before packaging, each sensor undergoes rigorous 100% testing for operate and release AT, Contact Resistance, and Variable Contact Resistance. Known for their omnipolar nature, these sensors can be triggered by either a north or south pole magnet, or both simultaneously. Optimal configuration of the AT band, magnet strength, and operating axis ensures precise control over the number of operate and release cycles, typically limited to one.
All dimensional measurements are provided in millimeters (mm), ensuring compatibility and ease of integration into diverse electronic applications. These sensors are ideal for applications where reliable, low-current switching is required in a compact SMD package. Whether used in consumer electronics, automotive systems, or industrial controls, the standard size R2 standard reed sensors offer dependable performance and longevity.
With their robust design and comprehensive testing procedures, this R2 standard size reed sensor meet stringent quality standards, making them a preferred choice for engineers seeking reliable and versatile reed switch solutions. Their ability to operate with flexibility in magnet polarity and precise control over switching cycles ensures consistent performance in demanding environments.
