Product Overview 1L-MSM-115 Reed Switch:
The 1L-MSM-115 Surface Mount Magnetic Reed Switch by 1 LEAP Technologies is a flange-mount magnetic switching device designed specifically for accurate open-close detection and position monitoring in surface-mounted installations. This model is made to provide the stable switching performance, controlled operating gaps, and long-term reliability in applications where accurate magnetic activation is required.
The 1L-MSM-115 is available in two distinct electrical configurations—Normally Open (NO) and Normally Closed (NC)—allowing system designers to select the proper logic based on operational and safety requirements. Both versions share the same mechanical housing but differ intentionally in their operating behaviour.
Key Features
- Mini stick-on surface mount design with side leads
- Made in flange for easy and secure mounting
- 18" long wire leads for flexible installation
- Minimum operating gap of ½" (12.0 mm)

Available Variants of 1L-MSM-115
1L-MSM-115 NO – Normally Open Magnetic Reed Switch
In the Normally Open (NO) configuration, the reed contacts remain open when no magnetic field is present. The circuit closes only when the magnet moves within the determined operating gap. This version is used where circuit activation is required only during magnetic presence.
1L-MSM-115 NC – Normally Closed Magnetic Reed Switch
In the Normally Closed (NC) configuration, the reed contacts remain closed under normal conditions and open when the magnet moves away beyond the specified distance. This version is mainly selected for fail-safe monitoring, where circuit interruption shows a change in position.
Mechanical Design and Construction
The 1L-MSM-115 features a rectangular enclosure with combined mounting flanges, allowing it to be securely installed on flat surfaces using screws. The supplied magnet unit is designed to align perfectly with the switch body, making sure the consistent magnetic interaction.
The surface-mount construction makes this model ideal for installations yet accurate alignment and repeatable switching are important. The housing is designed to stand by routine mechanical stress encountered in doors, panels, and enclosures.
Operating Gap Specification – Model-Specific Explanation
One of the most important and purposely engineered specifications of the 1L-MSM-115 magnetic reed switch is the difference in operating gap between the NO and NC versions.
Normally Open (NO): 12 mm minimum operating gap
Normally Closed (NC): 10 mm minimum operating gap
This difference is intentional and specific to this model, making sure the reliable and predictable switching performance.
Why the NO Version Has a 12 mm Minimum Operating Gap
In the NO magnetic reed switch, the contacts are naturally separated. To close the circuit, the approaching magnet must generate enough magnetic force to pull the reed blades together. This action requires a stronger and more focused magnetic field.
The 12 mm minimum operating gap is defined to makes sure that:
- The magnetic field strength is adequate to close the contacts reliably
- Accidental or weak magnetic influence does not cause false triggering
- The switch activates only when proper alignment and distance are achieved
This controlled gap increases an operational stability and making sure the consistent performance over repeated cycles.
Why the NC Version Has a 10 mm Minimum Operating Gap
In the NC magnetic reed switch, the contacts are already closed in their default state. The role of the magnet is to separate the contacts, which requires comparatively less magnetic force than closing an open contact.
As a result, the 1L-MSM-115 NC version is designed with a shorter minimum operating gap of 10 mm, allowing:
- Faster and more responsive contact opening
- Reliable operation in safety-critical monitoring systems
- Clear distinction between normal and triggered states
This difference making sure the dependable switching without compromising mechanical integrity.
Importance of Controlled Operating Gap in 1L-MSM-115
The carefully defined operating gaps in both NO and NC versions prevent overlap in switching behaviour and reduce uncertainty during installation. This makes sure that the 1L-MSM-115 magnetic reed switches perform always in real-world conditions, especially in applications involving repetitive door or panel movement.
Electrical Switching Characteristics
The 1L-MSM-115 operates as an SPST Reed Switch (Single Pole Single Throw), available in either NO or NC logic. This simple and hard switching configuration making sure the minimal electrical complexity and high reliability.
Although SPDT Reed Switch (Single Pole Double Throw) configurations exist in other product families, the 1L-MSM-115 is purpose-built as an SPST magnetic reed switch to maintain compact size and dependable surface-mount performance.
Application Areas for 1L-MSM-115
The 1L-MSM-115 is used only in applications that match its mechanical design, operating gap, and mounting style, such as:
- Magnetic door sensor systems
- Industrial cabinet and enclosure monitoring
- Access control and security systems
- Panel position sensing in automation equipment
- Surface-mounted installations requiring reliable magnetic switching
This model is not intended for compact consumer electronics like laptops or handheld devices.
Because of its small size and durable construction, the switch is perfect for scenarios where a small reed switch is required but performance cannot be compromised.
