📝Description
These micro miniature reed sensors are specifically engineered for high-efficiency, low-power switching applications, offering a significant cost advantage over standard-sized SMD reed sensors. The design incorporates pre-flattened leads that prevent any shock transfer during the SMD formation process, ensuring the sensor’s reliability and longevity.
Depending on the magnet type and the AT band chosen, these sensors support various activating distances, allowing flexibility in application requirements. Each sensor undergoes meticulous testing to ensure top-tier quality, including checks for Operate AT, Release AT, Static Contact Resistance, and Variable Contact Resistance, all of which are conducted with 100% accuracy before the sensors are packaged for shipment.
Committed to environmental sustainability, our products are completely Lead-free and comply with the RoHS directive, meeting global standards for hazardous substance restrictions.
Operating as an omni-polar device, this micro miniature reed sensor can be triggered by either a north pole, a south pole, or both simultaneously. To optimize performance, it is crucial to select the appropriate AT band, magnet strength, and operating axis, as this combination dictates the sensor’s precise operational parameters, ensuring reliable switching with minimal error.
For ease of integration into diverse electronic designs, all dimensions are provided in millimeters (mm), facilitating seamless compatibility across various applications. Whether employed in automotive electronics, consumer devices, or industrial automation, these micro miniature reed sensors excel in delivering dependable, energy-efficient switching solutions, making them an ideal choice for modern technological advancements.
