Introduction to the Haydon HAY-JB150 and its key features
TheHaydon HAY-JB150is a compact, weatherproof junction box designed for both outdoor and indoor electrical and low-voltage installations. Measuring 150 x 110 x 70 mm and moulded from halogen-free ABS, this IP65-rated enclosure provides a secure environment for cable terminations, small PCBs, connectors and other control connections. With a screw-down lid sealed by a gasket and four metal lid screws, the HAY-JB150 is intended to offer a practical balance of protection, durability and value for common installation needs.
- Ingress protection:IP65 — dust tight and protected against low-pressure water jets.
- Construction:Halogen-free ABS for impact resistance and UV stability.
- Sealing:Screw-down gasket lid with four metal screws for reliable sealing.
- Size and weight:Compact 150 x 110 x 70 mm footprint, light weight (~230 g) for easy handling and mounting.
- Insulation:Class II (IEC 61140) provides double insulation characteristics for certain applications.
Detailed specifications and benefits
Understanding the technical specifications helps explain where the HAY-JB150 performs best and what installers and specifiers should expect. The key specifications are practical and focused on small to medium junctions:
- Model:HAY-JB150
- External dimensions:150 x 110 x 70 mm — a compact footprint that suits conduit boxes, point-of-use terminations and small electronics modules.
- Material:Halogen-free ABS — offers good impact resistance, corrosion immunity and reduced risk of toxic gas in extreme fire conditions compared with halogenated plastics.
- Protection rating:IP65 — dust-tight and protected from water jets, making it suitable for exposed locations with rain splash or wash-down scenarios (verify cable entry solutions to retain IP rating).
- Insulation class:Class II (IEC 61140) — appropriate for double-insulated equipment where an earth connection to the enclosure is not required.
- Lid screws:Four metal screws — screw-down fastening gives a secure mechanical closure and good seal compression for the gasket.
- Operating temperature:-25°C to +60°C — covers the range for most temperate indoor and outdoor installations.
- Colour and weight:Grey colour, approx. 230 g — lightweight for easy mounting and handling.
- Weather and dust resistance:The IP65 rating provides reassurance in environments exposed to dust or occasional water jets. For permanent immersion or high-pressure cleaning, select a higher IP rating.
- Durability:ABS material is UV-resistant and impact-tolerant, so the enclosure will withstand typical external exposure and mechanical handling during installation.
- Ease of installation:A compact size and lightweight construction make the unit easy to site on walls, posts or inside cabinets. Multiple mounting options are possible—follow the manufacturer’s guidance for maintaining IP rating at cable entries.
- Safety:Class II insulation eliminates the need for earth bonding to the enclosure in many applications, simplifying some installations while still complying with electrical safety standards.
- Cost-effectiveness:With a suggested retail price around £9.99 (cost price example £4.50), the HAY-JB150 represents an economical choice for projects requiring many junction points without significant investment.
Use cases and scenarios where the HAY-JB150 excels
The HAY-JB150 is a versatile enclosure that is particularly well suited to a range of small-scale installation scenarios. Typical applications include:
- CCTV and surveillance junctions:Joining camera power and data cables, housing small surge protectors or compact connectors close to camera mounting points.
- Outdoor and indoor lighting terminations:Protecting LED driver terminations, lamp holders and control wiring for garden, pathway or signage lighting.
- Access control and low-voltage connections:Housing terminal blocks, door controller connections and proximity reader wiring in sheltered external positions.
- Sensor and switch junctions:Enclosing small electronics modules, sensor terminations and relay connections for environmental sensors, irrigation controllers or alarm devices.
- General-purpose electrical enclosure:Where an IP65 rated, non-metallic box is preferred—such as marine sheltered areas, light industrial spaces, or consumer outdoor projects.
In each of these scenarios, the compact footprint and straightforward sealing method make the HAY-JB150 a practical choice. To maintain IP65 performance, installers must use appropriate cable glands or conduit entries and ensure proper strain relief.
Comparisons with similar products on the market
When specifying a junction box, installers often weigh factors such as material, protection rating, size, price and mounting options. Here’s how the HAY-JB150 compares to common alternatives:
- Metal boxes (steel or aluminium) offer greater mechanical strength and sometimes higher temperature resistance, but they require earth bonding and may corrode unless treated. The HAY-JB150’s ABS construction avoids corrosion and bonding needs, making it quicker to install for low-voltage applications.
- Polycarbonate can provide higher impact strength and clearer UV longevity in some formulations, and some polycarbonate boxes offer transparent lids for display modules. Halogen-free ABS used in the HAY-JB150 balances cost and performance well for general-purpose outdoor use, though for extreme mechanical stress or where transparency is required, other materials may be preferable.
- IP66 and IP67 boxes protect against more aggressive ingress (powerful water jets or temporary immersion). If your installation faces frequent high-pressure cleaning, immersion risk or harsh offshore environments, opt for a higher IP-rated option. For many CCTV, lighting, and access control junctions that need protection from dust and normal rain, IP65 is sufficient and more cost-effective.
- The 150 x 110 x 70 mm size is smaller than many universal enclosures, so it suits point-of-use terminations but won’t hold larger power supplies or extensive PCBs. Its suggested retail price around £9.99 positions it as an economical solution for projects requiring multiple small enclosures.
Customer testimonials and installer feedback
Below are anonymised, illustrative comments that reflect the kinds of feedback installers and hobbyists often report for compact IP65 ABS junction boxes like the HAY-JB150. These are sample perspectives rather than verified endorsements.
- "Compact and easy to mount — used several for CCTV camera terminations and they’ve held up well outdoors. The gasket seal feels reliable when glands are fitted correctly." — installer (anonymous)
- "Good value for money. Lightweight and straightforward to wire inside. Make sure to use suitable cable glands to keep the IP rating intact." — systems integrator (anonymous)
- "Perfect for garden lighting controllers. Not too big, and the ABS finish resists fading in sun-exposed locations." — homeowner (anonymous)
When looking for user feedback, check retailer reviews and forum posts for real-world installation notes, and always confirm compliance requirements for your specific project.
Conclusion: Why the HAY-JB150 is a great choice
The Haydon HAY-JB150 offers a pragmatic combination of weatherproofing, material performance and affordability. Its IP65 rating and halogen-free ABS construction make it well-suited to a wide range of small outdoor and indoor junction needs — from CCTV and lighting to access control and sensor terminations. The screw-down gasket lid and metal screws provide a reliable sealing method, while the Class II insulation simplifies certain installations by removing the need for earthing the enclosure itself.
For installers and specifiers seeking a compact, cost-effective junction box that delivers dependable protection in everyday external conditions, the HAY-JB150 is a sensible option. Consider the enclosure when you need a lightweight, non-corroding housing that is simple to install and maintain. Always follow the manufacturer’s datasheet and local wiring regulations for cable entry methods, strain relief and any certification requirements relevant to your market.
In short, if your project requires a small, durable IP65 junction box at a competitive price point, the Haydon HAY-JB150 deserves consideration for its balance of performance, convenience and value.
