The 1L-MSM-113 Surface Mount Magnetic Reed Contact Switch by 1 LEAP Technologies is a custom-built magnetic sensing device designed for controlled, low-voltage DC switching applications. This model falls under the Surface Mount Magnetic Reed Contact Switch category and is made to provide consistent performance in security, automation, and industrial monitoring systems where stable magnetic activation and electrical reliability are important.
Unlike generic magnetic reed switches, the 1L-MSM-113 is developed with a clearly defined electrical and mechanical operating range, ensuring dependable switching behavior without compromising contact life or system safety. The product is available in both Normally Open (NO) and Normally Closed (NC) configurations, allowing flexibility in system design based on application logic.
Product Variants: Normally Open (NO) and Normally Closed (NC)
The Normally Open (NO) version of the 1L-MSM-113 remains electrically open when no magnet is present. When the paired magnet approaches the sensing zone, the internal reed contact closes and completes the circuit. This configuration is widely chosen in detection systems where the signal should activate only when a door, panel, or enclosure reaches a specific position.
The Normally Closed (NC) variant operates in the opposite manner. In this configuration, the reed contact remains closed under normal conditions and opens when the magnetic field is applied. This version is often selected for security and monitoring systems where a circuit interruption is used as a warning or fault signal. Both versions are mechanically identical and differ only in internal contact behavior.
Application-Specific Use Cases of 1L-MSM-113
The 1L-MSM-113 door reed switch magnet assembly is designed specifically for applications that operate safely within its electrical and mechanical limits. It is commonly used in door and window monitoring systems, industrial cabinet sensing, security alarm panels, access-control units, and automation enclosures.
It is also widely deployed in factory equipment monitoring, elevator door sensing, and electrical control panels, where a magnetic reed contact switch provides a simple yet highly reliable method of detecting physical movement or position.
Because of its defined voltage rating and physical size, this model is not intended for miniature consumer electronics or high-density computing devices. Its strength lies in stability, durability, and predictable performance in real-world industrial and commercial environments.
Why Only 200 VDC Rating?
One of the most important electrical characteristics of the 1L-MSM-113 is its maximum rated switching voltage of 200 VDC. This specification is not arbitrary; it is carefully defined based on the internal reed structure, contact material, and insulation design of this specific model.
The reed contacts inside the switch are hermetically sealed in a glass capsule filled with inert gas. While this construction provides excellent protection against oxidation and contamination, the physical contact gap and plating thickness are optimized for low-to-medium DC voltage levels. Operating above 200 VDC increases the possibility of electrical arcing during switching, which can shorten contact life and affect switching reliability.
By limiting the voltage rating to 200 VDC, the 1L-MSM-113 ensures controlled electrical stress on the reed blades, stable switching behavior, and long operational life. This makes the product ideal for sensing, signaling, and control circuits, but unsuitable for high-voltage or compact electronic devices such as laptops, where different sensor technologies are required.
