IP10 vs IP39K
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP10 and IP39K are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 3) and liquid protection (level 0 vs 9K). IP10 is rated for > 50 mm — back of hand and no protection, while IP39K provides > 2.5 mm — tool / wire and high-pressure, high-temp water jets.
IP10 provides protection against solid objects larger than 50 mm and no protection against water. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 0.
IP39K is an ingress protection code that ensures protection against solid objects larger than 2.5 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 9K.

The exact difference (IP10 vs IP39K)
Solid protection
IP10
Level 1 — > 50 mm — Back of Hand
IP39K
Level 3 — > 2.5 mm — Tool / Wire
IP10 provides "> 50 mm — Back of Hand" (level 1), while IP39K provides "> 2.5 mm — Tool / Wire" (level 3). IP39K is 2 levels higher.
Liquid protection
IP10
Level 0 — No Protection
IP39K
Level 9 — High-Pressure, High-Temp Water Jets
IP10 provides "No Protection" (level 0), while IP39K provides "High-Pressure, High-Temp Water Jets" (level 9). IP39K is 9 levels higher.

Recommendation
IP39K offers higher overall protection than IP10. Choose IP39K for harsher environments; IP10 may suffice for milder conditions and can be more cost-effective.
