📝 Description
The RM-1318 Reduced Miniature reed switches are meticulously crafted for applications where space constraints necessitate a compact design, yet there is a requirement for higher Contact Rating and Carry Current capabilities. Featuring reed blades renowned for their flexibility in contact closure force, these switches can reliably carry currents up to 1.5 A, ensuring robust performance in diverse operational environments.
To optimize assembly efficiency and sensitivity, the leads of this reduced miniature reed switch are flattened, facilitating precise orientation of the internal blades during soldering or welding processes. This design characteristic enhances in-group sensitivity, ensuring consistent and reliable operation. The availability of three distinct Release AT ranges further enhances versatility, accommodating a wide spectrum of application-specific requirements.
For applications demanding compactness, the cropped version of the RM-1318 Reduced Miniature Reed Switch is ideal, fitting seamlessly into smaller plastic housings and supporting direct soldering onto cables. In PCB assembly, the SMD variant enables efficient integration through reflow soldering processes, thereby enhancing manufacturing efficiency and reliability. Moreover, the vertical and horizontal mount versions cater to through hole PCB configurations, offering flexibility in installation based on specific project needs.
These features collectively position the RM-1318 Reduced Miniature reed switch as a preferred choice across industries such as automotive electronics, telecommunications, and industrial automation. Its combination of compact design, high current carrying capacity, and versatile mounting options makes it suitable for applications where space optimization and performance reliability are paramount. Whether deployed in consumer electronics or critical industrial systems, these reed switches deliver consistent functionality and durability, meeting the rigorous demands of modern technological applications.
