IP44 vs IP67 Industrial Sockets
The difference between these two ratings can determine the safety and reliability of your entire installation.
IP44
Indoor
IP67
Outdoor / Harsh
The IP (Ingress Protection) rating is the single most critical specification when selecting sockets for any environment beyond a clean, dry indoor space. Defined by IEC 60529, the IP code describes how well an enclosure resists solid particles and water — and choosing the wrong class results in product failure, electrical hazards and costly downtime.
How to Read an IP Code
IP X 4
First Digit — Solid Protection
Scale 0–6. Digit 4 = protection against objects ≥ 1 mm. Digit 6 = completely dust-tight — no ingress at all.
IP 4 X
Second Digit — Water Protection
Scale 0–9. Digit 4 = splashing water. Digit 7 = temporary immersion up to 1 metre for 30 minutes.
IP44
Indoor / Protected Outdoor
Protects Against
Solid objects larger than 1 mm
Water splashing from any direction
Immersion · Dust-tight · Jet water
Best For
Indoor workshops · Protected covered areas · Light industrial

IP67
Outdoor / Harsh Environments

Complete dust ingress — fully dust-tight
Temporary immersion: 1 m / 30 min
Heavy rain, marine spray, flooding
Best For

TRX Recommendation
When in doubt, specify IP67.
The cost difference between IP44 and IP67 is marginal. The cost of a single failure — product replacement, downtime, safety investigation — far exceeds it. TRX IP67 connectors are engineered for permanent exposure to outdoor, industrial and marine environments.
