IP28 vs IPX6
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP28 and IPX6 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 0) and liquid protection (level 8 vs 6). IP28 is rated for > 12.5 mm — finger and continuous immersion (manufacturer-specified), while IPX6 provides no protection and powerful water jets (12.5 mm nozzle).
Specified under IEC 60529, IP28 denotes protection against solid objects larger than 12.5 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 2 with second-digit (liquid) level 8.
IPX6 resists powerful water jets (12.5 mm nozzle, 100 kPa) with solid protection not specified. Suitable for heavy-rain or hose-exposed equipment where dust sealing is not required.

The exact difference (IP28 vs IPX6)
Solid protection
IP28
Level 2 — > 12.5 mm — Finger
IPX6
Level 0 — No Protection
IP28 provides "> 12.5 mm — Finger" (level 2), while IPX6 provides "No Protection" (level 0). IP28 is 2 levels higher.
Liquid protection
IP28
Level 8 — Continuous Immersion (manufacturer-specified)
IPX6
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP28 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IPX6 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)). IP28 provides 2 levels more liquid protection.

Recommendation
IP28 offers higher overall protection than IPX6. Choose IP28 for harsher environments; IPX6 may suffice for milder conditions and can be more cost-effective.
