What Is an IP67 Limit Switch?
An IP67 limit switch is a position-sensing switch sealed to the IP67 standard — fully dust-tight and able to withstand temporary immersion in water (up to 1 metre depth for 30 minutes). This makes IP67 limit switches the right specification for washdown areas, wet processing, outdoor flooding risk, and any environment where a switch may be submerged or repeatedly drenched. Where an IP65 switch would eventually let moisture in, an IP67 switch keeps the contact mechanism dry and reliable.
This guide explains the IP67 rating in detail, the features that deliver waterproof performance, and the industries that depend on IP67 limit switches.
What Does the IP67 Rating Mean?
Under IEC 60529, the two-digit IP code describes protection against solids and liquids:
- First digit “6” — dust: complete dust-tight protection. No dust ingress.
- Second digit “7” — water: protection against temporary immersion in water up to 1 metre deep for up to 30 minutes.
An IP67 limit switch therefore handles both dust and submersion — a higher water-protection level than IP65, which only resists water jets. Note that IP67 covers temporary immersion; for continuous submersion you would look at IP68.
Key Features of IP67 Limit Switches
- Fully sealed enclosure — high-grade gaskets and O-rings prevent water and dust ingress.
- Sealed actuator shaft and cable gland — closes off the two most common leak paths.
- Corrosion-resistant housing — die-cast metal or reinforced thermoplastic for wet service.
- Snap-action contacts — reliable, fast switching, typically 1NO + 1NC.
- Wide operating temperature range — for cold storage, washdown, and outdoor use.
- Multiple actuator styles — roller plunger, roller lever, and adjustable lever in vertical and horizontal formats.
IP67 vs IP65: Choosing the Right Seal
Both IP65 and IP67 limit switches are dust-tight. The difference is water protection: IP65 resists jets and splashing, while IP67 withstands temporary immersion. Specify IP67 when the switch faces high-pressure washdown, standing water, or submersion risk; IP65 is sufficient for dust and occasional splashing. See our full IP65 vs IP67 comparison to decide.
Industrial Applications of IP67 Limit Switches
IP67 limit switches are essential wherever equipment is regularly wet or washed down:
- Food & beverage processing — hygienic washdown lines requiring waterproof switches.
- Dairy & bottling plants — wet floors and frequent cleaning cycles.
- Pharmaceutical & clean processing — high-hygiene washdown areas.
- Water & wastewater treatment — gates, valves, and flood-prone equipment.
- Car wash & cleaning systems — constant water exposure.
- Marine & dockside equipment — splash and immersion risk.
- Outdoor automation — gates and machinery in flood-prone or coastal areas.
- Chemical & process plants — wet and corrosive conditions.

Frequently Asked Questions
What does IP67 mean on a limit switch?
IP67 means the limit switch is completely dust-tight and can withstand temporary immersion in water up to 1 metre deep for 30 minutes. It is suitable for washdown and wet environments.
Is an IP67 limit switch fully waterproof?
An IP67 limit switch is waterproof against temporary immersion. For continuous, permanent submersion, an IP68-rated switch is required.
What is the difference between IP65 and IP67 limit switches?
Both are dust-tight. IP65 protects against water jets and splashing; IP67 protects against temporary immersion. IP67 offers stronger water protection. See our IP65 vs IP67 limit switch comparison for full details.
Where are IP67 limit switches used?
IP67 limit switches are used in food and beverage processing, washdown lines, water treatment, car washes, and other wet or flood-prone environments. For a broader overview, visit our limit switch guide.
