Waterproof instrument security monitoring power supply box in ABS plastic, F4B-1 model, with dimensions 100mm by 68mm by 40mm, designed for housing electronic components and available in the pictured colour.
F4B-1 ABS Plastic Waterproof Box for Security Monitoring Power Supplies

This F4B-1 model waterproof instrument box is designed to provide a secure, protective housing for critical electronic components such as security monitoring power supplies. Manufactured from ABS plastic, it offers a balance of structural integrity and environmental resistance in a compact form factor measuring 100mm by 68mm by 40mm. It addresses the practical need for a dedicated, purpose-built enclosure that safeguards sensitive electronics from dust, moisture, and physical knocks, which is essential for maintaining reliable system operation in both professional and demanding environments. The product is also listed as available for custom processing, providing flexibility for projects with unique dimensional or specification requirements.
Features and Construction

The box is defined by its core specifications and material choice, which directly inform its application and durability. Its construction is centred around practical protection for housed electronics.
Material and Build
The enclosure is made from ABS (Acrylonitrile Butadiene Styrene) plastic. This engineering thermoplastic is widely used for protective casings due to its favourable properties: it is inherently strong and rigid, providing good impact resistance to protect internal components from accidental bumps. Its dimensional stability helps the box maintain its shape under typical loads, and the material itself is lightweight, which simplifies handling and installation. The 'waterproof instrument box' designation suggests the design incorporates features to resist water ingress, making it suitable for environments where condensation or light moisture exposure is a concern.
Size and Practical Fit
The external dimensions are clearly stated as 100mm in length, 68mm in width, and 40mm in height. This specific 100x68x40mm footprint defines a compact enclosure, ideal for installations where space is at a premium, such as within control panels, behind mounting racks, or in confined equipment areas. These measurements allow users to accurately plan the spatial requirements for their power supply or other instrumentation. The internal cavity will be slightly smaller to account for the wall thickness, so these external dimensions are crucial for assessing the fit within an allocated space, while the internal volume must be checked against the components it needs to house.
Uses and Placement

The product's primary use case is clearly directed towards electronic applications, specifically as a protective shell. Its value lies in organising and securing electronic assemblies.
Event or Professional Use
In professional security system installations, a dedicated power supply unit is often required to deliver stable voltage to cameras, sensors, and control panels. This F4B-1 box serves as an ideal housing for such a power supply, consolidating wiring and components into a single, protected unit. This improves system tidiness, safety, and reliability. The waterproof nature of the box adds a layer of protection for installations in semi-protected outdoor areas, utility rooms, or basements where humidity may be higher than in controlled indoor environments, thereby helping to prolong the lifespan of the electronic components inside.
Everyday Home Use
For DIY electronics enthusiasts, makers, or homeowners installing their own basic monitoring systems, this box offers a professional-grade finishing touch. It can house custom-built power circuits, Raspberry Pi projects, or sensor hubs, moving them from an exposed breadboard state to a more permanent and protected enclosure. The ABS plastic is easy to drill or cut for custom cable ports or mounting holes if needed, supporting personalised modifications. Its clean, functional appearance also makes it suitable for installations within a garage, shed, or workshop where electronic projects require safeguarding from dust and occasional moisture.
Benefits and Buying Value

The value of this product is rooted in its specific design for a clear purpose, its material properties, and the practical benefits of using a dedicated enclosure.
Reuse and Low Maintenance
A key benefit of a robust enclosure like this is its potential for reuse across different projects. The durable ABS plastic construction means it can withstand being opened and closed multiple times if components need upgrading or replacing. Maintenance is minimal; the plastic surface can be wiped clean if it accumulates dust, and its non-corrosive nature means it won't degrade in typical indoor environments. By protecting the more valuable and sensitive electronics inside, this box acts as a long-term asset, reducing the risk of damage that would require costly component replacements and supporting sustainable use through multiple project lifecycles.
Why Choose This Product
Choosing this specific F4B-1 model provides certainty. You are selecting a product with defined dimensions (100x68x40mm) and a known material (ABS plastic), which allows for precise integration into your plans. The 'waterproof instrument box' classification gives confidence in its suitability for its intended protective role. Furthermore, the option for custom processing, as indicated in the source, adds significant value for buyers with non-standard requirements, offering a solution that off-the-shelf enclosures may not provide. It represents a practical, no-nonsense component for anyone needing a reliable, purpose-specified housing for electronic power supplies or instrumentation.
