Recessed Mount Construction for Hidden Installation

The recessed mount design of the 1L-MSR-104B magnetic switch allows the sensor to be installed inside a pre-drilled cavity, keeping the switch body completely concealed within the mounting material. This installation method not only enhances the appearance of the system but also provides additional protection against physical damage, accidental impacts, and environmental exposure.

The flush-mounted structure makes this recessed reed switch ideal for installations where external protruding sensors are not desired. Once installed, the switch integrates seamlessly into the surface, reducing the risk of tampering and increasing long-term operational stability in fixed installations.

3/8" Diameter Body for Secure Fit

The 3/8″ diameter housing of the 1L-MSR-104B is engineered to ensure a tight and secure fit within standard drilled holes. This precise sizing minimizes movement inside the mounting cavity, ensuring stable sensor alignment throughout its service life.

This feature is particularly important in industrial environments where vibration or repeated operation could otherwise cause sensor displacement. The well-balanced body dimensions allow the electronic reed switch to remain firmly positioned, maintaining consistent switching behavior over time.

Longer Length Design with 18" Wire Leads

A key feature of the 1L-MSR-104B recessed mount magnetic switch is its 18″ long wire leads, which provide extended reach and superior installation convenience. The longer wire length allows installers to route cables easily through panels, frames, or enclosures without requiring additional wire extensions or junctions.

This design significantly reduces installation complexity and helps maintain a clean wiring layout. The extended leads are especially beneficial in control panels and industrial enclosures where the connection point may be located at a distance from the mounting position of the switch.

Operate Gap of ¾" (19mm) for Reliable Performance

The operate gap of ¾” (19mm) minimum ensures dependable magnetic activation even when perfect alignment between the switch and magnet is not achievable. This wider operating gap enhances tolerance to installation variations, making the 1L-MSR-104B magnetic switch suitable for applications where movement, spacing differences, or structural tolerances are present.

This capability improves system reliability by reducing missed detections or inconsistent switching, especially in industrial automation and access monitoring systems that demand stable and repeatable operation.

Easy and Quick Installation Process

The 1L-MSR-104B recessed reed switch is designed for easy and quick installation, helping reduce overall installation time and labor effort. The recessed mounting method eliminates the need for external brackets, surface housings, or additional hardware.

With its standard 3/8″ diameter body and extended wire leads, installers can complete installations efficiently while ensuring a neat and professional result. This makes the switch well-suited for OEM integration and large-scale deployment projects.

Application Areas for 1L-MSR-104B

The 1L-MSR-104B magnetic switch is specifically intended for applications that require hidden mounting, longer sensing distance, and robust construction. Typical application areas include:

Industrial & Automation Systems

Used in industrial machinery, automation equipment, and control systems where concealed sensors are preferred for safety and durability.

Electrical Panels & Enclosures

Ideal for detecting door or panel status in electrical cabinets and enclosures where reliable magnetic sensing is essential.

Access Control & Security Installations

Suitable for access doors, frames, and secured compartments requiring flush-mounted sensors with extended operating gaps.

Commercial Equipment Installations

Applied in commercial equipment where clean aesthetics, hidden mounting, and consistent performance are critical.

This model is not designed for compact consumer electronics such as laptops or handheld devices. The 1L-MSR-104B is purpose-built for structural and industrial applications where size, mounting depth, and operating gap are important factors.
