📝 Description
These latching reed sensors feature an integrated biasing magnet, that is carefully calibrated to provide its bi-stable function. The whole enclosure is molded and the alloy construction includes pre-flattened leads that prevent shock transfer during SMD formation, ensuring reliability throughout assembly. Depending on the specific magnet employed, these sensors offer customizable latching and unlatching distances.
Each latching reed sensor undergoes rigorous testing, including 100% checks for Operate AT, Release AT, Static Contact Resistance, and Variable Contact Resistance prior to packaging. The functionality of the normally closed sensor contact is influenced by the alignment of magnetic poles: alternate opposing poles cause the contact to release and operate.
These sensors are ideal for applications requiring dependable and precise switching under varying conditions. Whether in industrial automation, automotive systems, or consumer electronics, their robust design and thorough quality assurance make them a reliable choice for critical sensing tasks.
These bi-stable latching reed sensors with integrated biasing magnets offer unparalleled reliability and performance. Their design considerations and meticulous testing ensure they meet the demands of modern electronic and mechanical systems, providing consistent operation and longevity in diverse environments.
