Product Design and Construction
The 1L-MSM-114 magnetic reed sensor features a slim, rectangular surface-mount housing that allows easy installation on flat surfaces such as doors, frames, panels, and enclosures. The hard outer body protects the internally sealed electronic reed switch, which is enclosed in a hermetically sealed glass capsule. This sealed design prevents oxidation and contamination of the contact surfaces, making sure a stable switching over millions of operations.
The switch operates overall through magnetic actuation, meaning there is no physical contact between moving parts. When a compatible magnet approaches the sensing zone, the internal reed contacts align and close the circuit. Once the magnetic field is removed, the contacts return to their normally open state. This non-contact operation makes the 1L-MSM-114 highly reliable for repetitive sensing tasks.
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 making sure 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 property 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 Pull 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.
Power Rating Explained – Why the 1L-MSM-114 Is Rated at 10 W
One of the most important specifications of the 1L-MSM-114 Surface Mount Magnetic Reed Switch is its maximum power rating of 10 watts. This rating defines the maximum electrical load that the internal reed contacts can safely switch without risking performance degradation or premature failure.
The 10 W power limitation is not a drawback but a calculated engineering decision based on the internal construction of the reed contacts. Reed switches operate using very fine, precision-aligned metal reeds sealed inside a glass envelope. While this structure provides excellent sensitivity and longevity, it is not designed to handle high electrical loads. Higher power levels would generate excessive heat or electrical arcing at the contact points, which could weld the contacts together or permanently damage the switch.
By limiting the power rating to 10 W, 1 LEAP Technologies makes sure that the 1L-MSM-114 provides consistent switching performance, long contact life, and reliable operation across millions of cycles. This rating makes the switch ideal for signal-level switching, low-current sensing, and control circuit applications rather than power-driven devices.
Operational Purpose of the 10 W Design
The 1L-MSM-114 is specifically engineered for low-power detection and control systems, not for energy-consuming devices. The 10 W rating makes sure the clean signal transmission and prevents electrical stress on the reed contacts. This is why the switch performs exceptionally well when connected to control panels, alarm circuits, PLC inputs, and monitoring systems.
Because of this design philosophy, the 1L-MSM-114 is not suitable for laptops, motors, heaters, or high-load electronic equipment. Those applications demand higher current and power handling, which fall outside the safe operating limits of this model.
Application Areas – Where the 1L-MSM-114 Is Used
The 1L-MSM-114 magnetic reed switch is hugely used in applications where accurate position sensing and non-contact switching are required. It is commonly installed in door and window monitoring systems, where it detects opening and closing actions with high accuracy. In industrial environments, it is used for panel position detection, making sure that enclosures remain closed during operation.
This model is also suitable for industrial automation systems, where it functions as a magnetic reed sensor providing input signals to controllers or PLCs. Additionally, it is frequently used in security and alarm systems, acting as a reliable trigger for intrusion detection. Its stable electrical characteristics make it ideal for low-power control circuits that demand dependable ON/OFF signaling.
Product Reliability and Performance
Thanks to its sealed electronic reed switch design, the 1L-MSM-114 provides an excellent resistance to dust, moisture, and environmental contaminants. The surface-mount housing provides mechanical stability, while the internal contacts maintain consistent performance over extended usage periods. This reliability makes the product suitable for installations where maintenance access is limited.
The switch operates silently, consumes no power in standby mode, and requires no physical force to actuate, further increasing its longevity and performance consistency.
