The 1L-MSM-111 Surface Mount Magnetic Reed Switch Sensor by 1 LEAP Technologies is a high-reliability magnetic switch made for accurate non-contact sensing in security, automation, and industrial monitoring applications. This model is specifically designed for surface-mount installation, making it ideal for systems where flush or embedded mounting is not practicable. The switch operates using magnetic activation, ensuring stable performance, a long service life, and dependable switching without mechanical wear.
This model is manufactured with a strong ABS plastic housing and comes with pre-attached PVC-insulated lead wires, enabling quick and secure electrical connections. The surface-mount form factor allows easy installation on doors, panels, cabinets, and enclosures without altering the structure of the mounting surface.
The 1L-MSM-111 is available in multiple contact options to fit different operational needs. The Normally Open (NO) reed switch version remains open in the absence of a magnetic field and closes when the magnet comes within the specified operating range. The Normally Closed (NC) version reacts oppositely, remaining closed until the magnet is removed. For applications requiring both outputs, the NO/NC (changeover) configuration provides greater flexibility in control and monitoring systems.
Key Features
- Easy screw and adhesive tape (optional) mounting
- Huge Operating Gap: 5/8″ (16mm) min.
- 18″ long wire leads
Electrical Performance and Reliability
Designed for low-power and control-signal applications, the 1L-MSM-111 Reed Switch Sensor provides reliable switching performance within its rated electrical specifications. The reed contacts provide stable signal transmission, minimal electrical noise, and a high mechanical life rating, allowing the switch to operate efficiently over millions of switching cycles.
The non-contact magnetic operation reduces mechanical friction and wear, ensuring long-term consistency. This makes the 1L-MSM-111 Reed Switch especially suitable for applications where frequent opening and closing actions occur.
