IP26 vs IP48
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP26 and IP48 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 2 vs 4) and liquid protection (level 6 vs 8). IP26 is rated for > 12.5 mm — finger and powerful water jets (12.5 mm nozzle), while IP48 provides > 1 mm — small wires and continuous immersion (manufacturer-specified).
Built to withstand protection against solid objects larger than 12.5 mm and protection against powerful water jets. Water projected in powerful jets by a 12.5 mm nozzle against the enclosure from any direction shall have no harmful effects.. Classified as IEC 60529 ingress protection code IP26, it pairs solid level 2 with liquid level 6.
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 (IP26 vs IP48)
Solid protection
IP26
Level 2 — > 12.5 mm — Finger
IP48
Level 4 — > 1 mm — Small Wires
IP26 provides "> 12.5 mm — Finger" (level 2), while IP48 provides "> 1 mm — Small Wires" (level 4). IP48 is 2 levels higher.
Liquid protection
IP26
Level 6 — Powerful Water Jets (12.5 mm nozzle)
IP48
Level 8 — Continuous Immersion (manufacturer-specified)
IP26 handles 100 kPa (Powerful Water Jets (12.5 mm nozzle)), while IP48 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)). IP48 provides 2 levels more liquid protection.

Recommendation
IP48 offers higher overall protection than IP26. Choose IP48 for harsher environments; IP26 may suffice for milder conditions and can be more cost-effective.
