📝Description
This reed sensor with integrated resistor serves dual purposes: it can be utilised for level sensing applications or to provide contact protection. Alternatively, a diode can replace the resistor, with the sensor’s dot marking indicating polarity for convenient orientation. The sensor offers multiple activation distances, contingent upon the magnet type and AT band employed, catering to diverse operational requirements.
Prior to packaging, all sensors undergo rigorous 100% testing to verify their performance across crucial parameters such as Operate AT, Release AT, Static Contact Resistance, and Variable Contact Resistance. This meticulous testing regimen ensures that each reed sensor with integrated resistor, meets stringent quality standards, guaranteeing reliable functionality in real-world applications.
The sensor’s omni-polar nature enables it to be activated by either a north pole, south pole, or both, offering flexibility in magnet orientation. Engineers can further optimize performance by selecting appropriate AT bands, magnet strengths, and operating axes, ensuring precise control with a single operate and release cycle per activation to prevent unintended switching.
In specialized float applications, a ring magnet can encircle the sensor to enhance functionality, demonstrating the sensor’s adaptability across various industrial and consumer electronics settings. Whether integrated into automotive systems, HVAC equipment, or security devices, its robust design and configurable features make it a preferred choice for engineers seeking reliable and versatile sensor solutions.
This reed sensor with integrated resistor, combines advanced design features with comprehensive testing and environmental compliance, making it an ideal solution for demanding electronic applications where precision, reliability, and environmental responsibility are paramount.
