Detailed description of specifications and benefits
The HAY-JB240’s specification sheet presents a straightforward, purpose-built product intended for outdoor junctions and accessory housing. The external dimensions of 240 x 190 x 90 mm make it large enough to accommodate small terminal blocks, junctions for low-voltage CCTV cabling, or modest control modules while remaining compact enough for wall- or pole-mount applications.
- IP65 Ingress Protection— The IP65 rating means the enclosure is dust-tight and offers protection from water jets. This makes the box suitable for exposed exterior walls, under eaves, and locations where occasional heavy rain or cleaning jets may be present. It is not submerged, so it is not intended for underwater or sustained immersion applications.
- Material: Halogen-free ABS— ABS offers good impact resistance and dimensional stability in moderate temperatures, while the halogen-free formulation reduces toxic halogen content in the event of fire. The grey colour is neutral and suitable for many outdoor installations where discreet appearance is desired.
- Class II insulation— Double insulation reduces reliance on protective earth for safety in certain installations. This is useful when housing low-voltage equipment or simple electrical junctions, but final installation requirements should be confirmed with a qualified electrician and the applicable regulations.
- Lid fastening with 4 metal screws— A removable cover secured by metal screws provides a solid mechanical joint and makes it straightforward to access wiring for maintenance or changes. Metal screws typically give better long-term retention than plastic fasteners in outdoor use.
- Operating Temperature— The stated approximate range of −25 °C to +60 °C covers most external ambient conditions in temperate climates, making the box suitable for year-round outdoor use in many regions.
- Weight and form factor— At around 600 g, the unit is light enough for easy handling and mounting, and its rectangular form factor supports straightforward internal layout of cables, gland fittings or small circuit boards.
Limitations and important details: the published reseller listing does not provide internal usable dimensions, mounting-hole patterns or specific knockout/gland positions. For installations that require precise internal layout, panel mounting or specific gland placements, consult the official Haydon datasheet or supplier for mechanical drawings and detailed specifications.
Use cases and scenarios where the HAY-JB240 excels
The HAY-JB240 is a versatile option for many light to medium-duty outdoor housing needs. Typical use cases include:
- Outdoor electrical junctions— Ideal for protecting wire splices and terminal blocks for lighting circuits, garden power outlets, timers and irrigation controllers where IP65 protection is sufficient.
- CCTV and security accessory housing— A common application is housing small CCTV junctions, connector blocks, PoE splitters or simple accessory electronics mounted near cameras or sensors to keep connections dry and secure.
- Small electronics protection— Suitable for low-power sensor interfaces, junctions for environmental monitoring equipment or control relays that need basic weather protection without the bulk of a larger enclosure.
- Temporary or semi-permanent outdoor installations— Because it is lightweight and easy to mount, the HAY-JB240 works well for temporary site installations or retrofit projects where a permanent, heavy-duty enclosure is not necessary.
- Light industrial and telecom accessory housing— Where enclosures do not require high-impact resistance or chemical resistance, this box can serve as a neat, cost-effective housing solution.
For installations that demand higher impact resistance, chemical resistance, or submersion protection, or where specific cable gland patterns are required, an alternative enclosure specification should be selected.
Comparisons with similar products on the market
When selecting an outdoor junction box, buyers commonly compare material, ingress rating, size, mounting features and price. Here is how the HAY-JB240 stacks up against typical alternatives:
- ABS vs Polycarbonate— ABS is generally durable, cost-effective and offers good impact resistance for many uses. Polycarbonate enclosures can offer superior impact resistance and higher temperature tolerance but are typically more expensive. For many standard outdoor junctions where extreme impact or prolonged UV exposure is a concern, polycarbonate may be preferred; however, for routine protective housing the HAY-JB240’s ABS construction is a practical choice.
- IP65 vs higher IP ratings (IP66 / IP67)— IP65 protects against dust and water jets, which suits most overhead exposure situations. If equipment will be submerged (IP67) or exposed to powerful water jets/pressure washing (often better handled by IP66 or higher), then a higher-rated enclosure should be selected. Consider the installation environment when deciding if IP65 is sufficient.
- Plastic vs Metal enclosures— Metal boxes (aluminium or stainless steel) provide superior mechanical strength, grounding options and higher temperature tolerance. They tend to be heavier, more costly and may require treatment against corrosion. The HAY-JB240’s plastic construction is lighter, cheaper and non-conductive (matching Class II insulation), which can be advantageous in some electrical applications.
- Price and value— With a suggested price of approximately 12.99 and a cost price around 10.20 (reseller listing), the HAY-JB240 sits in the budget-friendly segment for IP65 enclosures of this size. It provides a balance of weather protection and affordability compared with premium polycarbonate or metal alternatives.
Customer testimonials and reviews
At the time of writing, no verified customer testimonials or user reviews were supplied with the product specification provided here. For real-world feedback, check reseller listings, industry forums or contact distributors who may be able to share installer experiences.
That said, typical installer feedback for enclosures of this type often highlights a few recurring points:
- Ease of access — Removable lid with metal screws is appreciated for straightforward maintenance.
- Value for money — Installers often comment that ABS IP65 boxes offer excellent value when heavy-duty mechanical protection is not required.
- Limitations — Requests for clearer internal dimensions and gland/kockout details are common; these are valuable for pre-planned installations.
Conclusion: Why the HAY-JB240 is a strong choice
The Haydon HAY-JB240 IP65 outdoor junction box is a sensible, cost-effective choice for many outdoor electrical and small-electronic housing needs. Its IP65 rating, halogen-free ABS construction, Class II insulation and practical size make it well suited to CCTV accessory housing, outdoor junctions for lighting and garden circuits, and small monitoring or control electronics.
Key reasons to consider the HAY-JB240 include its affordability, lightweight form factor, secure lid fastening and suitability for a broad range of temperate outdoor environments. However, prospective buyers should verify specific installation requirements: confirm whether IP65 is sufficient for the intended environment, obtain the official Haydon datasheet for exact internal dimensions and mounting-hole patterns, and ensure installation is carried out by a qualified electrician where regulations require it.
In summary, for installers and DIYers seeking a compact, economical weatherproof enclosure for non-submersion outdoor applications, the HAY-JB240 represents a practical and dependable option — provided its dimensional and ingress characteristics match the needs of the project.
