IP65 vs IP68 Linear Actuator

Ingress protection (IP) ratings describe how well an enclosure resists dust and water. For electric linear actuators, the wrong IP choice is a leading cause of outdoor and wash-down field failures—corroded boards, seized screws, swollen seals and warranty disputes. This OEM guide explains IP65 vs IP68 (and nearby ratings) in practical buyer language, then shows how to read Elerover Protection Class values on live product pages.

Elerover manufactures indoor, industrial outdoor and sealed tubular actuator families. Marketing titles sometimes emphasize a product-family theme (for example “IP68 tubular”). Selection must follow the specification table. Start from the Linear Actuator category and confirm Protection Class on every SKU you shortlist.

What IP codes mean (buyer-oriented)

An IP code has two characteristic numerals:

1. Solid particle protection (first digit) — dust and foreign objects
2. Liquid ingress protection (second digit) — dripping, spraying, jets, immersion

For actuators, you will most often see IP54/IP55 in protected indoor use, IP65/IP66 in outdoor industrial machines, and higher ratings on sealed designs intended for wetter duty. Exact laboratory conditions are defined by IEC 60529; manufacturer immersion depths and durations for IP68 are product-specific.

Comparison table: common actuator IP ratings

Rating	Dust	Water (typical meaning)	Common OEM context
IP54–IP55	Limited	Splashing	Protected indoor / light splash
IP65	Dust-tight	Low-pressure water jets	Outdoor enclosures, agriculture, many industrial machines
IP66	Dust-tight	Powerful water jets	Harsher outdoor / wash-adjacent duty
IP67	Dust-tight	Temporary immersion (defined)	Wet environments per datasheet test
IP68	Dust-tight	Continuous immersion (manufacturer-defined)	Sealed outdoor / wet OEM when specified
IP69 / IP69K	Dust-tight	High-pressure, high-temperature jets	Specialized wash-down equipment

“Higher number” is not automatically the right buy. Over-specifying IP can add cost and still fail if connectors or mounting create leak paths.

IP65 vs IP68: how to decide

Choose IP65 when

• The actuator sees rain, dust and occasional hose spray—not continuous immersion
• The machine is outdoor industrial, agricultural or solar-adjacent
• Cable glands and connectors are specified as part of the sealed system
• You need industrial force platforms such as SLA08 or SLA08B

Consider IP66 when

• Spray is powerful or frequent
• Equipment is cleaned more aggressively than light rinse
• The datasheet explicitly publishes IP66 on Protection Class

Consider IP68 (when the specs say so) when

• The design intent includes prolonged wet exposure or immersion conditions defined by the manufacturer
• You are evaluating sealed tubular platforms such as the waterproof tubular series
• You will verify the exact Protection Class on the model page (for example SLA16M)

Consider IP69 / IP69K when

• High-pressure hot wash-down is part of sanitation or process cleaning
• Review models that publish that rating, such as SLA023

Selection criteria beyond the two digits

IP rating alone does not finish the environmental design review:

1. Temperature range — seals and grease behave differently in cold/heat
2. UV and outdoor aging — housings and cables need suitable materials
3. Duty cycle — wet + high duty accelerates wear
4. Force and voltage — still sized separately (force guide, 12V vs 24V)
5. Connector strategy — mated waterproof connectors vs open splices
6. Orientation and drainage — standing water pockets at glands are failure magnets
7. Maintenance access — sealed units still need inspection plans

Decision tree for OEM buyers

1. Is the actuator indoors and dry? → Lower IP may be acceptable; still protect cable entry.
2. Is it outdoors in rain/dust without immersion? → Start with IP65/IP66 industrial platforms.
3. Is there regular hose-down? → Prefer IP66+ and confirm connector sealing.
4. Is there immersion or continuous wetting? → Only models whose Protection Class explicitly supports it.
5. Is there high-pressure hot wash? → Look for IP69/IP69K on the specs table.
6. Open the product page and copy the Protection Class into your RFQ checklist.

Engineering examples

Example A — Farm cover actuator

• Environment: dust, rain, occasional spray
• Force: mid to high kN
• Immersion: no

Path: Linear Actuator → SLA08 or SLA08B → confirm Protection Class IP65/IP66 on the chosen stroke model. Combine with force sizing from the force calculation guide.

Example B — Compact architectural / façade OEM

• Envelope: small diameter preferred
• Environment: outdoor wet
• Force: moderate

Path: Category → waterproof tubular series → SLA16M. Read Protection Class carefully; do not assume every tubular SKU shares identical sealing.

Example C — Vehicle hatch, outdoor industrial

• Force: high (see heavy-duty guide)
• Environment: road spray, rain

Path: Category → SLA-12K → SLA-12K heavy-duty actuator. Confirm Max Load and Protection Class together.

Example D — Food / wash-down adjacent equipment

• Cleaning: high-pressure jets

Path: Evaluate models publishing IP69/IP69K such as SLA023, then confirm force and stroke fit.

Applications

Application	Typical IP emphasis	Notes
Indoor furniture	Lower IP	Focus on noise and sync
Medical indoor	Protected environment	Still manage cleaning chemicals
Agriculture	IP65/IP66	Dust + rain dominate
Solar assists	Outdoor IP65+	Long strokes; verify seals
Marine-adjacent	Higher sealing	Confirm immersion claims carefully
Wash-down process	IP69 class	Spec-table verification required

Name vs specification: manufacturer policy

Elerover’s buyer guidance is explicit:

• Trust Protection Class / IP Rating on the specifications table
• Treat series names as navigation aids, not lab certificates
• If title and specs disagree, ask for confirmation via Contact before PO

This protects OEM programs from assuming immersion capability that a particular stroke model does not publish.

Recommended Elerover product path

1. Resource (this guide) → define environment and cleaning method
2. Category: Linear Actuator
3. Series: SLA08, SLA08B, SLA-12K, waterproof tubular
4. Products: verify Protection Class + Max Load + Working Voltage on the SKU
5. Contact: include environment photos or cleaning procedure in the RFQ

Sealing is a system: glands, rods and connectors

An actuator housing rating can be undermined by integration details:

• Unmated connectors left open during install or service
• Field-cut cables without proper glands
• Bent rods / side load that damage rod wipers and admit slurry
• Standing water pooled on upward-facing connectors
• Pressure washing aimed at seals not designed for IP69-class jets
• Chemical cleaners incompatible with seal materials

When you RFQ Elerover, describe the cleaning method and connector preference. OEM cable and connector options on supported platforms exist specifically to keep the installed system as sealed as the datasheet implies.

Outdoor aging and maintenance

IP tests are laboratory events; field life also depends on:

• UV exposure on jackets and housings
• Thermal cycling that works seals
• Abrasive dust that wears wipers
• Long idle periods that allow moisture ingress if vents/paths exist

Define inspection intervals for outdoor fleets—especially agricultural and solar installs. A sealed actuator is not “fit and forget” when duty is harsh.

Comparing competitor IP claims (buyer caution)

IP marketing varies across the industry. Professional OEM practice:

1. Demand the Protection Class string for the exact SKU
2. Ask for the test basis if immersion (IP68) is claimed
3. Reject catalog language that only says “waterproof” without a code
4. Align cable accessories to the same environmental goal

Elerover’s position is conservative on purpose: the specification table wins. That protects your compliance file when customers audit the BOM.

Failure modes linked to IP mismatch

Environment reality	Underspecified IP result	Better path
Rain + dust farm	Board corrosion, grit in screw	IP65/IP66 industrial series
Daily hose-down	Water at cable entry	Higher jet rating + sealed connectors
Immersion events	Catastrophic ingress	Only SKUs with matching Protection Class
Hot high-pressure wash	Seal extrusion / ingress	IP69-class models when published
Indoor splash only	Unnecessary cost if over-specified	Right-sized lower IP with protected install

Integration checklist for sealed installs

• Protection Class copied from product page into drawing notes
• Connector mating sequence defined in work instructions
• Cable strain relief prevents gland leverage
• Mounts keep rod coaxial (protects wipers)
• Orientation avoids persistent water traps where possible
• Cleaning SOP matches the rating (no surprise pressure wash)
• Spare part SKU locked to the same Protection Class
