📝Description
This Micro Miniature reed switch is engineered for applications requiring moderate power and low load capacities. Its fast operate time makes it well-suited for high-speed switching scenarios, ensuring efficient performance across various industrial and consumer electronics applications. Compared to the UM-0018 Ultra-miniature series, this reed switch offers a cost-effective solution without compromising on reliability or functionality.
The leads of this micro miniature switch are flattened, facilitating precise orientation of the internal blades during assembly processes such as soldering or welding. This feature optimizes the orientation for maximum sensitivity and consistency in operation. Additionally, the availability of three different Release AT types caters to a wide range of specific application requirements, enhancing versatility and customization options.
For compact designs, the cropped version of the Micro Miniature Reed Switch is suitable, fitting seamlessly into smaller plastic housings and offering flexibility for direct soldering onto cables. In PCB assembly, the SMD version supports reflow soldering processes, ensuring secure and efficient integration onto surface-mount technology boards. Furthermore, vertical and horizontal mount versions accommodate through hole PCB configurations, providing ease of installation across different mounting orientations.
These features collectively position the Micro Miniature reed switch as a reliable choice across industries such as telecommunications, automotive electronics, and medical devices. Its combination of cost-effectiveness, fast switching capability, and versatile mounting options makes it ideal for applications where space constraints and performance requirements are critical considerations. Whether used in consumer electronics or industrial automation, this reed switch delivers consistent performance and durability, meeting the evolving demands of modern technological applications.
