Normally Open Reed sensors are widely used in various industries, offering reliable and efficient proximity sensing solutions. One of the popular types of forms is the normally open SMD (Surface Mount Device) reed sensor, designed to provide dependable performance in compact applications.

With its small and compact size, the normally open SMD reed sensor offers ease of integration into various electronic devices and equipment. This type of reed sensor can be conveniently mounted on printed circuit boards (PCBs) using surface mount technology, allowing for seamless integration in space-constrained applications.

The normally open SMD reed sensor operates on the principle of a normally open contact. In its standby state, the reed switch remains open, creating a gap between the contacts. When a magnetic field is applied, the contacts close, allowing for electrical continuity. This property makes it an ideal choice for applications that require a normally open contact, such as door and window sensors, security systems, and proximity switches.

The normally open SMD reed sensor offers a high switching speed, enabling it to detect and respond quickly to changes in the magnetic field. This ensures accurate and precise sensing, enhancing the overall performance of the system in high speed applications. Moreover, the reed sensor's hermetically sealed switch contacts provide excellent protection against environmental factors such as dust, moisture, and vibrations, ensuring long-term reliability in harsh operating conditions.

Normally Open type SMD reed sensors are Omni-polar devices that actuate with either pole of magnet. These sensors are supplied in tapes conforming to IEC 60286-3 standards, for automatic pick and place. For environmental reasons, the leads are plated with pure Tin, which is Lead-free.

Our SMD Reed Sensors comprise of our R5 and R4 Ultra-miniature devices, which have a very tiny PCB pad layout, and can be perform well in switching low level loads, in Mobile devices and IOT applications. Our R3 and R2 and more robust devices which switch 10W loads and withstand higher shock and vibration in automotive and white goods applications.

Complete Specifications, Drawing, Actuation distances, Usage Notes, and Applications will help select the right product. In conclusion, the normally open SMD reed sensor offers a compact, reliable, and versatile solution for proximity sensing applications. Its small form factor, high switching speed, and customizable sensitivity make it an ideal choice for a wide range of industries, ensuring seamless integration and enhanced performance.
