IP65 and IP67 look like a one-digit difference — in practice, that digit is the line between “protected from dust and jets of water” and “protected from dust and full submersion,” and picking the wrong one for your environment either overspends or under-protects.
TL;DR
- IP65 protects against dust ingress and water jets from any direction — sufficient for most road vehicle and general fleet use
- IP67 adds protection against temporary full submersion — relevant for mining, off-road, and wash-down environments
- The first digit (dust) is identical between the two; the second digit (water) is where they diverge
- Overspending on IP67 for a road fleet isn’t harmful, just an unnecessary cost if IP65 already covers the actual exposure
What the Numbers Actually Mean
The IP (Ingress Protection) rating’s first digit covers solid particle protection, the second covers liquid. IP65 and IP67 share the same top dust protection (6) — the difference is entirely in the water rating: 5 means protected against low-pressure water jets from any direction; 7 means protected against temporary immersion up to 1 meter for up to 30 minutes.
IP65 vs IP67 at a Glance
| IP65 | IP67 | |
|---|---|---|
| Dust protection | Fully dust-tight | Fully dust-tight (same) |
| Water protection | Low-pressure jets, any direction | Temporary submersion, 1m / 30min |
| Typical use case | Road vehicles, delivery fleets | Mining, off-road, wash-down bays |
| Relative cost | Lower | Higher |
| Risk of over-spec’ing | N/A | Paying for unused protection on road fleets |
When IP65 Is Sufficient
Standard road vehicles, delivery fleets, and general logistics — covered in Logistics & Transportation — typically face rain, wash-down, and road spray, all within IP65’s water-jet protection. IP67’s added submersion resistance goes largely unused in this environment.
When IP67 Becomes Necessary
Mining sites, off-road agricultural equipment working through flooded fields, and any environment with a real risk of temporary submersion (deep puddles, wash bays with standing water) justify IP67’s added protection — this is covered in more depth in our Mining: Rugged Terminals guide, where dust and moisture exposure both run higher than standard road conditions.
A Deployment Example
An equipment rental company standardized on IP67 terminals across its entire fleet — including delivery vans that never left paved roads — reasoning that “higher is always safer.” When reviewing hardware costs a year later, the delivery-van units had never once been exposed to submersion-risk conditions; the IP67 premium on those specific units had bought protection the vehicles never needed, while the mining and construction units in the same fleet used the submersion rating regularly. Splitting the spec by actual deployment condition — IP65 for road vehicles, IP67 for site equipment — would have cut hardware cost on the van fleet without changing durability outcomes.
Matching the Rating to Your Actual Deployment
The mistake to avoid isn’t choosing IP65 for a mine site or IP67 for a delivery van — it’s not checking which conditions the specific deployment actually faces before defaulting to whichever rating sounds more impressive. Full certification context is covered in IP67 & MIL-STD-810 Explained.
Common Questions
Does a higher IP rating always mean a more durable tablet overall?
No — IP rating covers dust/water ingress specifically; shock and vibration resistance is a separate certification (MIL-STD-810), and both matter independently.
Can an IP65 tablet be used temporarily in an IP67 environment without damage?
Occasional light exposure likely won’t cause immediate failure, but sustained deployment in submersion-risk conditions beyond the rated protection will eventually cause ingress failure.
Is IP68 available, and when would it be needed?
IP68 (deeper/longer submersion) exists but is rarely necessary for vehicle-mount terminals — it’s more common in dedicated underwater equipment.
Can a mixed fleet run different IP ratings on different vehicles?
Yes — matching the rating to each vehicle type’s actual exposure (as in the rental fleet example above) is standard practice and avoids overspending across the whole fleet.
