Waterproof Box — IP65 IP67 ABS Plastic Enclosure for Electronics & PCB

Waterproof Enclosures — IP65/IP67 ABS Plastic Boxes for Electronics, PCB & Outdoor IoT Applications

Waterproof electronic enclosures protect PCBs, sensors, controllers, and electronic assemblies from moisture, dust, and environmental contamination. Rated to IP65 (dust-tight, water jet resistant) and IP67 (dust-tight, immersion to 1m for 30 minutes) per IEC 60529, these ABS plastic enclosures are the standard solution for outdoor IoT devices, industrial control panels, junction boxes, LED driver housings, and any electronics installation exposed to weather or washdown environments. This collection provides a comprehensive range of waterproof enclosure sizes and configurations for prototyping and production.

IP Rating Reference Guide

• IP65 — Dust-tight (no ingress) + protected against water jets from any direction. Suitable for outdoor installations, industrial environments with washdown, and applications exposed to rain and splashing water. The most common rating for outdoor electronics enclosures.
• IP67 — Dust-tight + protected against temporary immersion in water up to 1m depth for 30 minutes. Required for applications that may be submerged (flood-prone outdoor installations, underwater sensors, marine electronics).
• IP68 — Dust-tight + protected against continuous immersion beyond 1m (manufacturer-specified depth and duration). For permanently submerged applications.

Enclosure Size Range

Our waterproof enclosure range covers the most commonly needed sizes for electronics projects and production:

• Medium: 150×100×70mm, 160×110×70mm, 200×120×75mm — for Raspberry Pi, relay boards, and multi-channel controllers
• Large: 250×150×100mm, 300×200×130mm — for industrial control panels, power supplies, and multi-board assemblies
• Extra large: 380×280×180mm, 400×300×200mm — for large industrial enclosures and junction boxes

• Prototyping: Weatherproof Arduino/ESP32/Raspberry Pi project enclosures

Waterproof Enclosure Buying Guide

Step 1 — Choose IP rating: IP65 is sufficient for most outdoor applications (rain, splashing, washdown). IP67 is required for applications that may be temporarily submerged (flood-prone areas, marine use). IP68 is for permanently submerged applications.

Step 2 — Choose size: Measure your PCB and add clearance for connectors, wiring, and cable glands. Allow at least 10mm clearance on all sides of the PCB. Consider future expansion when selecting enclosure size.

Step 3 — Solid vs clear lid: Solid ABS lids provide maximum UV and impact resistance. Clear PC lids allow visual inspection of the interior and are required for LED displays or status indicators visible through the lid. Clear PC lids have slightly lower UV resistance than solid ABS.

Step 4 — Cable entry: Use cable glands (PG7 for cables up to 6mm, PG9 for up to 8mm, PG11 for up to 10mm, PG13.5 for up to 12mm, PG16 for up to 14mm, PG21 for up to 18mm) to maintain IP rating when routing cables into the enclosure. Pre-drill or punch holes to the correct diameter for your cable gland size.

Frequently Asked Questions

Q: What is the difference between IP65 and IP67?
A: IP65 protects against water jets from any direction but not immersion. IP67 protects against temporary immersion up to 1m for 30 minutes. For most outdoor applications (rain, splashing), IP65 is sufficient. For flood-prone or marine applications, use IP67.

Q: Can I drill holes in a waterproof enclosure without losing the IP rating?
A: Yes, provided you use properly rated cable glands in all holes. Cable glands with the appropriate IP rating (IP65 or IP67) maintain the enclosure's ingress protection when correctly installed. Unused holes must be plugged with IP-rated blanking plugs.

Q: Are ABS enclosures suitable for outdoor UV exposure?
A: Standard ABS has limited UV resistance and may yellow and become brittle after prolonged outdoor exposure. For long-term outdoor installations (2+ years), use UV-stabilized ABS enclosures or apply UV-protective coating. Our UV-stabilized variants are specifically formulated for outdoor use.

Q: What PCB mounting options are available inside the enclosure?
A: Our enclosures include internal mounting bosses (M3 or M4 threaded) for PCB standoffs. PCB mounting standoffs (M3 × 5mm, 6mm, 8mm, 10mm) are available separately. The boss positions vary by enclosure size — check the dimensional drawing for your specific enclosure.

Q: Do you stock cable glands for waterproof enclosures?
A: Yes. We stock PG7, PG9, PG11, PG13.5, PG16, and PG21 cable glands in nylon (IP65/IP68) and stainless steel (IP68) variants, compatible with all our waterproof enclosures.
