The 1L-MSR-106 almirah door contact switch from 1 LEAP Technologies is a heavy-duty industrial magnetic designed specifically for steel doors and fixed structural installations where reliability, strength, and precise sensing are critical. This model is engineered with a ¾” diameter press-fit body, allowing it to be securely mounted inside steel or rigid material surfaces while maintaining a clean, flush appearance.
Unlike light-duty electronic switches, Model 1L-MSR-106 is developed only for industrial and architectural use cases, where a wide operating gap, robust wiring, and stable contact performance are required. This makes it a preferred choice among industrial reed switch suppliers and system integrators working on large-scale projects.
Key Features
- ¾” Dia Press Fit Steel door contact
- Wide Operating Gap 1 3/8″ (35mm) min.
- 18″ long wire Leads
- Easy & Quick Installation.
Robust Press-Fit Design for Doors
One of the defining characteristics of the 1L-MSR-106 is its ¾ inch diameter press-fit construction, which is specifically optimized for door applications. The press-fit mounting ensures that once installed, the switch remains firmly locked inside the drilled cavity without the need for additional brackets or surface fixtures.
This recessed mounting style not only improves mechanical stability but also protects the switch from external impact, vibration, and tampering. As a recessed mount magnetic switch, it is ideal for environments where exposed components are not acceptable, such as industrial facilities, architectural projects, and shipbuilding installations.
18″ Long Wire Leads for Installation Flexibility
To support flexible and efficient installation, 1L-MSR-106 almirah door contact switch is supplied with 18-inch long wire leads. These pre-attached leads allow easy routing through door frames, control panels, or junction boxes without the need for immediate extensions or connectors.
This feature significantly reduces installation time and effort, especially in large industrial setups and architectural projects where wiring paths are longer and more complex. The long leads also help maintain secure electrical connections, enhancing the overall reliability of the electronic switch assembly.
Easy & Quick Installation
The press-fit recessed design, combined with factory-attached wire leads, makes the 1L-MSR-106 extremely easy and quick to install. Once the correct diameter hole is drilled, the switch can be inserted directly into place, resulting in a neat, professional finish.
This installation simplicity is particularly valuable in projects with tight timelines, such as shipbuilding yards and commercial construction sites, where efficiency and repeatability are essential.
Applications of 1L-MSR-106
The 1L-MSR-106 is specifically suited for applications where steel structures, heavy doors, and recessed mounting are required. Typical application areas include:
Ship Building & Marine Structures
In shipbuilding environments, equipment must withstand vibration, moisture, and mechanical stress. The recessed, press-fit construction of this magnetic switch ensures secure installation in steel bulkheads, access panels, and doors used in marine vessels.
Architectural & Commercial Construction
Architectural projects demand hidden, aesthetically clean installations. The recessed mounting and flush finish of Model 1L-MSR-106 make it ideal for commercial buildings, industrial gates, and architectural steel doors where visible sensors are not desirable.
Industrial Door & Panel Monitoring
This switch is widely used for monitoring the open/close status of heavy industrial doors, safety enclosures, and access panels in factories and processing plants.
Security & Access Control Systems
With its wide operating gap and stable contact performance, the 1L-MSR-106 is well-suited for access control systems where consistent door position detection is essential.
