IP29K vs IP48
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP29K and IP48 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 4) and liquid protection (level 9K vs 8). IP29K is rated for > 12.5 mm — finger and high-pressure, high-temp water jets, while IP48 provides > 1 mm — small wires and continuous immersion (manufacturer-specified).
With IP29K, an enclosure receives protection against solid objects larger than 12.5 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 2 with second-digit (liquid) level 9K.
Engineered to deliver protection against solid objects larger than 1.0 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. Classified as IEC 60529 ingress protection code IP48, it pairs solid level 4 with liquid level 8.

The exact difference (IP29K vs IP48)
Solid protection
IP29K
Level 2 — > 12.5 mm — Finger
IP48
Level 4 — > 1 mm — Small Wires
IP29K provides "> 12.5 mm — Finger" (level 2), while IP48 provides "> 1 mm — Small Wires" (level 4). IP48 is 2 levels higher.
Liquid protection
IP29K
Level 9 — High-Pressure, High-Temp Water Jets
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP29K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP29K provides 1 level more liquid protection.

Recommendation
IP48 offers higher overall protection than IP29K. Choose IP48 for harsher environments; IP29K may suffice for milder conditions and can be more cost-effective.
