📝 Description
These ultra-miniature cylindrical magnet sensors excel in low-level switching applications, offering a significant size advantage over other cylindrical sensors. Their compact design makes them ideal for applications where space is limited without compromising on performance. Depending on the magnet type and AT band selected, these sensors provide a range of activating distances, allowing for precise adaptation to specific operational needs.
For enhanced flexibility, the sensor can be customized with non-standard connectors upon request, accommodating unique integration requirements in diverse industrial and consumer electronics applications. Before shipment, each of these magnet sensors undergo rigorous 100% testing to ensure it meets stringent quality standards. Testing includes evaluations for operate and release times (AT), Contact Resistance, and Variable Contact Resistance, guaranteeing reliable and consistent performance upon installation.
These ultra miniature Cylindrical magnet sensors are particularly suited for pneumatic cylinder end position sensing applications, and EV connectors and chargers where their compact size and robust construction ensure reliable operation in challenging environments. Their omni-polar capability enables activation by either a north pole, south pole, or both magnetic polarities, providing versatility in magnet orientation.
Engineers can optimize sensor performance by selecting the appropriate AT band, magnet strength, and operating axis, ensuring precise control over switching operations. This customization helps to limit the sensor to a single operate and release cycle per activation, minimizing unintended switching events and enhancing overall system reliability.
These ultra-miniature cylindrical magnet sensors combine compact design with comprehensive testing and versatile features, making them indispensable in applications requiring efficient, reliable, and space-saving switching solutions. Whether integrated into industrial automation, robotics, or consumer electronics, their performance and adaptability meet the stringent demands of modern technological advancements.
