📝Description

This ultra miniature PCB mountable reed sensor presented here is specifically engineered to handle switching up to 10W. Its design features internal blades that consistently align parallel to the sensor’s top surface. Each sensor undergoes rigorous 100% testing for operate and release characteristics, ensuring reliable performance across various conditions including AT (Actuation Time), Contact Resistance, and Variable Contact Resistance before it is packaged for distribution.

As an omni-polar device, this ultra miniature PCB mountable reed sensor is capable of activation by either a north pole, south pole, or both, offering versatility in magnet orientation. Selecting the appropriate AT band, magnet strength, and operational axis is crucial, as it determines the specific conditions under which the sensor will activate and release. This customization helps to streamline its functionality, ensuring precise operation where only one actuation and release cycle is desired.

The compact nature of this PCB mountable sensor makes it ideal for applications where space is limited yet reliable switching capabilities are essential. Whether integrated into consumer electronics, industrial machinery, or automotive systems, its consistent performance and robust design make it a dependable choice for engineers and designers alike.

This ultra miniature PCB mountable reed sensor combines miniature size with high-performance standards, catering to diverse applications that demand efficient and reliable switching of up to 10W. Its meticulous testing and versatile magnetic responsiveness underscore its suitability for modern electronic and mechanical designs requiring precision and durability.
