IP05 vs IP38
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP38 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 5 vs 8). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP38 provides > 2.5 mm — tool / wire and continuous immersion (manufacturer-specified).
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 5.
IP38 provides protection against solid objects larger than 2.5 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 8.

The exact difference (IP05 vs IP38)
Solid protection
IP05
Level 0 — No Protection
IP38
Level 3 — > 2.5 mm — Tool / Wire
IP05 provides "No Protection" (level 0), while IP38 provides "> 2.5 mm — Tool / Wire" (level 3). IP38 is 3 levels higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP38
Level 8 — Continuous Immersion (manufacturer-specified)
IP05 handles 30 kPa (Water Jets (6.3 mm nozzle)), while IP38 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP38 provides 3 levels more liquid protection.

Recommendation
IP38 offers higher overall protection than IP05. Choose IP38 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
