📝 Description
This micro miniature PCB mountable reed sensor described here is designed for efficient switching capabilities up to 10W. Its internal blades maintain a consistent parallel alignment with the sensor’s top surface, ensuring reliable performance in various operational environments.
Prior to packaging, each sensor undergoes rigorous 100% testing to validate its operational integrity. Tests include thorough evaluations of operate and release times (AT), as well as assessments for Contact Resistance and Variable Contact Resistance. This stringent quality control process guarantees that every sensor meets stringent performance standards before it reaches the customer.
As an omni-polar device, this micro miniature PCB mountable reed sensor offers the flexibility to be activated by either a north pole, south pole, or both, depending on the specific application requirements. The ability to respond to different magnetic polarities enhances its versatility in diverse settings.
To optimize its functionality, engineers can fine-tune parameters such as the AT band, magnet strength, and operating axis. These adjustments ensure that the sensor reliably triggers a single operate and release cycle per intended activation, preventing unintended responses and ensuring precise control in critical applications.
Due to its compact size and robust design, this micro miniature PCB mountable reed sensor is well-suited for integration into space-constrained electronic assemblies across industries. Whether utilized in consumer electronics, automotive systems, or industrial equipment, its dependable performance and adaptable magnetic characteristics make it a preferred choice for engineers seeking reliable switching solutions.
