The 1L-MSM-114 Surface Mount Magnetic Door Reed Switch is a precision-engineered magnetic reed switch manufactured by 1 LEAP Technologies for reliable, low-power magnetic activation applications. This model is designed as a Normally Open (NO) contact, meaning the circuit remains open in its default state and closes only when an external magnetic field is applied. Due to its sealed construction and surface-mount design, this switch provides stable performance in controlled industrial and security environments where accurate position sensing is required.
This product belongs to the Surface Mount Magnetic Door Reed Switch category and functions as a no-contact switch, reducing mechanical wear and extending operational life. The model 1L-MSM-114 is available in standard lead-wire configuration, while the 1L-MSM-114T variant provides terminal-based connections, as shown in the images. Both variants are built around the same electrical and magnetic performance principles, ensuring consistent output behavior.
Key Highlights
- Huge-gap operation for increased installation flexibility
- 4-foot long, durable 22 AWG PVC cable (NO version)
- Screw-mount design suitable for wood, metal, and PVC surfaces
- Rugged ABS plastic housing in a clean grey finish
- Excellent mechanical endurance exceeding 10 million cycles
- Strong 50 mm minimum operating gap for reliable activation
- Low contact resistance of 0.1 Ω ensures clean signal transmission
In addition to its compact design, the 1L-MSM-114 NO features a robust reed switch mechanism that responds instantly to magnetic field changes. Consequently, installers can count on clean signal transitions every time a door or gate opens or closes. Because the switch operates in a normally open state, it integrates seamlessly with standard alarm and automation controllers without requiring additional signal inversion. Furthermore, its surface-mount form factor makes installation straightforward, whether you attach it to a door frame, a panel housing, or any other mounting surface.
Wide Gap Magnetic Reed Switch – 1L-MSM-114
The 1L-MSM-114 Surface Mount Magnetic Reed Switch from 1 LEAP Technologies is designed as a Wide Gap Magnetic Reed Switch, meaning it can reliably operate even when there is a relatively larger distance between the switch body and the activation magnet. This wide sensing gap allows flexible installation in applications where exact mechanical alignment is difficult or where slight movement, vibration, or tolerance variations are expected.
The wide gap capability ensures consistent switching performance without requiring close-contact positioning, while still maintaining the model’s low-power 10 W rating and normally open (NO) operation. This makes the 1L-MSM-114 especially suitable for door, panel, and enclosure monitoring systems where stable magnetic detection is needed over a broader activation range, while preserving the durability, non-contact operation, and long service life characteristic of 1 LEAP Technologies magnetic reed switches.
Electrical Configuration – SPST Normally Open Contact
The 1L-MSM-114 is configured as an SPST Reed Switch (Single Pole Single Throw) with a Normally Open (NO) contact arrangement. In its idle condition, the circuit remains open. When exposed to a magnetic field, the contacts close and allow current flow. This straightforward switching behavior makes the product ideal for detection-based applications where a simple ON/OFF signal is required.
Although SPDT Reed Switch (Single Pole Double Throw) configurations exist in the reed switch category, this specific model is intentionally designed as SPST to maintain simplicity, reliability, and electrical stability within its rated limits.
