Linear Technik is pleased to announce the availability of the Moteck MK52 IPX8M Linear Actuator — a fully submersible electric actuator designed for demanding environments where standard motion components simply cannot perform.

Most linear actuators are rated for dust and splash resistance. The MK52 goes considerably further. Carrying an IPX8M waterproof certification, this actuator is built to operate under continuous submersion — opening up applications in marine engineering, aquaculture, water treatment, outdoor automation, and heavy industrial washdown environments that were previously difficult or impossible to serve with standard electric actuation.

Available now through Linear Technik, the MK52 is backed by our technical team for application support, sizing, and fast delivery to customers across all Australian states and territories.

What IPX8M actually means

IPX8 is the highest standard waterproof rating under the IEC 60529 ingress protection scale. The M designation indicates the rating applies to moving parts and dynamic seals — not just a static housing. The MK52 is certified for continuous submersion beyond 1 metre depth, making it suitable for underwater operation in real-world conditions.

Standard IP ratings — IP65, IP67 — protect against jets and brief immersion. IPX8M is a different category entirely. It certifies that the actuator’s seals remain effective during motion, under sustained water pressure. For applications where equipment is regularly or permanently submerged, or exposed to continuous high-pressure water, this distinction matters significantly.

Engineers designing for marine, aquaculture, and water infrastructure environments will understand the challenge: corrosion, seal failure, and moisture ingress are among the most common causes of actuator replacement in these settings. The MK52 addresses this at the certification level rather than relying on secondary enclosures or workarounds.

Applications

The MK52 is well suited to a broad range of applications where conventional electric actuators struggle with moisture, submersion, or aggressive washdown conditions.

Marine equipment
Hatch actuation, trim systems, underwater mechanisms, boat lifts
Aquaculture
Feeding systems, pen gates, submerged positioning equipment
Water treatment
Valve actuation, weir gates, submerged flow control
Outdoor automation
Irrigation, solar tracking, exposed or weather-facing equipment
Industrial washdown
Food processing, dairy, beverage, pharmaceutical production lines
Infrastructure
Flood gates, stormwater systems, dam and reservoir control

Design note for engineers: The MK52 accepts 12V or 24V DC input, making it straightforward to integrate into both mobile/battery-powered systems and fixed 24V industrial control architectures. At 3,500N maximum push load and 4.7 mm/s no-load speed, it suits moderate-force positioning applications. Contact the Linear Technik technical team to confirm suitability for your specific load, stroke, duty cycle, and mounting requirements.

Why Moteck

Moteck is a globally recognised manufacturer of electric linear actuators, with a reputation built on product reliability and application-specific engineering. The MK52 reflects Moteck’s approach of designing for specific environmental challenges rather than relying on generic IP ratings applied to standard products.

The MK52’s IPX8M certification is independently tested and verified — not a specification inherited from component ratings. For machine builders and system integrators who carry responsibility for long-term system reliability in wet environments, this distinction provides a meaningful level of confidence in the field.

Frequently asked questions

What does IPX8M mean and how is it different from IP67 or IP68?
IPX8 is the highest waterproof rating under IEC 60529, certifying the actuator for continuous submersion beyond 1 metre. The M suffix indicates the rating applies during movement — meaning the dynamic seals are tested under operational conditions, not just the static housing. IP67 and IP68 ratings cover brief or defined submersion but do not necessarily certify performance during operation in the same way.
What voltage does the MK52 operate on?

The MK52 accepts 12V or 24V DC input, making it compatible with both battery-powered mobile systems and standard 24V industrial control architectures.

What is the maximum load capacity of the MK52?
The MK52 has a maximum push load of 3,500N. For pull load ratings and dynamic load specifications for your specific application, contact the Linear Technik technical team.
Is the MK52 suitable for saltwater environments?
The MK52 is designed for submersible operation and is used in marine and aquaculture applications. For specific material compatibility with seawater or chemical environments, we recommend confirming with our technical team before specifying.
Can Linear Technik assist with integration and mounting advice?
Yes. Our technical team provides application engineering support including load and stroke assessment, mounting configuration advice, and control system integration guidance. Contact us before finalising your design if you have specific requirements.
Is the MK52 available for same-day dispatch in Australia?
