Design & Construction of 1L-MSR-101
The 1L-MSR-101 recessed reed switch features a 1/4 inch cylindrical press-fit body, allowing it to be securely installed into pre-drilled holes without the need for external brackets, screws, or clamps. This press-fit design making sure the firm placement and prevents movement during operation.
The recessed switches construction keeps the switch protected from physical impact, accidental damage, and environmental exposure. Once installed, the switch remains hidden within the mounting surface, making it perfect for industrial panels, doors, and equipment housings where uncover sensors are not advisable.
Operating Performance & Sensing Distance
The 1L-MSR-101 recessed magnetic switch operates with a minimum operating gap of 1/2 inch (12 mm) between the switch and its corresponding magnet. This defined sensing distance allows for valid and repeatable activation in applications where exact alignment may vary little bit due to mechanical tolerances.
The stable operating gap making sure dependable switching performance over repeated cycles, making this model suitable for systems that require continuous monitoring of door, panel, or cover positions.
Wiring & Installation Flexibility
This model is provided with 18-inch long wire leads, it is enough length for appropriate routing inside control panels, cabinets, and enclosures. The extended leads reduce installation complexity by reducing the need for additional wire joints or extensions.
The long lead design allows easy combination into automation systems, security circuits, and monitoring devices, majorly in recessed installations where access space may be limited.
Recessed Mount Magnetic Switch Advantage
As a recessed mount magnetic switch, the 1L-MSR-101 provides major advantages over surface-mounted sensors. The hide installation not only increase protection but also improves system longevity by reducing exposure to external forces, dust, and accidental involvement. This makes the switch particularly perfect for industrial environments where equipment safety, clean installation, and long-term performance are important.
Model-Specific Applications of 1L-MSR-101
The 1L-MSR-101 is designed purely for applications that require recessed magnetic sensing. Typical use cases include:
Industrial Control Panels & Cabinets
Used for detecting the open or closed position of electrical panels, automation cabinets, and control enclosures.
Machine Safety & Access Monitoring
Installed in machinery guards, safety covers, and access doors to monitor position status and making sure an operational safety.
Security & Access Control Systems
Used in concealed door and frame installations where tamper-resistant and hidden sensors are required.
Commercial & Industrial Infrastructure
Suitable for equipment housings, service doors, and enclosures requiring flush-mounted magnetic sensing.
Furniture & Modular Furniture Applications
The 1L-MSR-101 recessed reed switch is hugely used in furniture applications, such as wardrobes, cabinets, drawers, and modular furniture systems. The press-fit recessed design allows the switch to be hidden inside wooden or laminated panels, providing clean aesthetics while enabling door position detection, lighting control activation, or access monitoring within furniture units.
This model is not intended for compact electronic devices or consumer products, but is optimized for mechanical and industrial installations.

Frequently Asked Questions (FAQs)
Is the 1L MSR 101 suitable for soft-closing wardrobes and drawers?
Yes, the 1L MSR 101 magnetic reed switch works with soft-closing systems as long as the magnet and switch align properly at the final closed position. Just ensure the soft-close mechanism doesn’t leave extra gap at the end.
Will the 1L MSR 101 work on sliding wardrobes and almirahs?
Yes, but only if the sliding door passes directly in front of the magnet. If the door shifts sideways while sliding, alignment may break, so the mounting position must be chosen carefully.
Can nearby metal hinges affect the performance of the 1L MSR 101 in furniture?
In some cases, yes. Metal hinges placed very close to the magnetic reed switch can reduce sensitivity. Keeping a small distance from heavy hardware ensures consistent detection.
