📝 Description
This standard size NC reed sensor, is produced with an integrated biasing magnet. Designed with pre-flattened leads and molded to withstand SMD formation without transferring shock, it offers ensure robust performance in diverse applications. Available in various activating distances determined by the magnet and AT band utilised, this NC reed sensor undergoes rigorous 100% testing for AT release, Static Contact Resistance, and Variable Contact Resistance prior to packaging, ensuring consistent quality.
The principle behind their operation lies in the interaction between opposing poles of the magnet and sensor, which causes the normally closed sensor contact to release. Selecting the appropriate AT band, magnet strength, and operating axis is crucial, as it influences the sensor’s ability to limit the number of operates and releases to a single cycle, enhancing longevity and performance predictability. Another key factor to note is that biased sensors exhibit a phenomenon known as re-closure if the magnet is brought too near the sensor.
These sensors adhere to precise dimensions measured in millimeters (mm), emphasizing compatibility and ease of integration into various electronic assemblies. Their advanced design and manufacturing standards help aid high precision sensing. As technology evolves, these SMD reed sensors continue to set benchmarks in reliability and performance, supporting innovations across a spectrum of industrial and consumer electronic products.
