IP49K vs IPX8
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP49K and IPX8 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 4 vs 0) and liquid protection (level 9K vs 8). IP49K is rated for > 1 mm — small wires and high-pressure, high-temp water jets, while IPX8 provides no protection and continuous immersion (manufacturer-specified).
Built to withstand protection against solid objects larger than 1.0 mm and resistance to high-pressure (8–10 MPa), high-temperature (80 °C) water jets. Classified as IEC 60529 ingress protection code IP49K, it pairs solid level 4 with liquid level 9K.
IPX8 protects against continuous immersion under manufacturer-specified conditions (depth and duration), with solid protection not specified. The standard for submersible consumer electronics.

The exact difference (IP49K vs IPX8)
Solid protection
IP49K
Level 4 — > 1 mm — Small Wires
IPX8
Level 0 — No Protection
IP49K provides "> 1 mm — Small Wires" (level 4), while IPX8 provides "No Protection" (level 0). IP49K is 4 levels higher.
Liquid protection
IP49K
Level 9 — High-Pressure, High-Temp Water Jets
IPX8
Level 8 — Continuous Immersion (manufacturer-specified)
IP49K handles 8–10 MPa (High-Pressure, High-Temp Water Jets), while IPX8 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP49K provides 1 level more liquid protection.

Recommendation
IP49K offers higher overall protection than IPX8. Choose IP49K for harsher environments; IPX8 may suffice for milder conditions and can be more cost-effective.
