Problem: Outdoor motion control fails when you need it most
That solar tracker that stalls after a storm.
The irrigation valve that sticks during planting season.
The camera that jams in salt spray by the pier.
You rely on motion to do work outdoors. Standard servos work indoors. They fail in rain dust salt and sun. When they fail you lose time money and trust. You face downtime that costs more than the part. You need an actuator that keeps moving no matter the weather.
Agitate: Small failures become big headaches
Imagine a solar farm in spring. Panels need tracking. One actuator fails in a storm and a whole row drops out of alignment. Energy drops during peak sun. Technicians drive hours to replace a unit. You lose yield and pay for service calls. That single failure adds up.
Think about a research ROV on a dive. A cheap servo takes in water. The manipulator seizes. The mission stops. Deep sea missions cost thousands per day. Failure is not an option.
Or picture a greenhouse where valves stick from fertilizer splash. Crops dry out. Yields fall. You fix it once but the problem repeats.
These scenarios feel familiar to our customers. They cost time money and peace of mind. They push teams to build workarounds that add complexity. You shouldn’t have to live with that.
Solution: Waterproof servo motor actuators fix outdoor pain fast
We at Jimi Technology design and build waterproof servo motor actuators for outdoor use that stop failures before they start. Our units use smart sealing corrosion resistant housings and sealed feedback devices so they work in rain salt spray dust and even brief submersion. They give you precision torque and long life with low maintenance.
Below we walk through how these actuators work how to pick the right unit and how Jimi supports your project from prototype to production.
What is a waterproof servo motor actuator?
A servo motor plus motion mechanics and sealing make a waterproof actuator. It converts electrical signals into repeatable linear or rotary motion. We seal the motor and feedback system with O-rings, gaskets, or potting compounds. We use IP-rated connectors and corrosion-resistant materials like stainless steel and anodized aluminum. That keeps water dust and chemicals out so the actuator keeps moving.
How waterproof actuators differ from standard servos
- Sealed housings and rated connectors stop ingress.
- Marine-grade materials resist corrosion in salt air.
- Sealed encoders and potentiometers keep feedback accurate.
- Pressure compensation and potting allow IP68 or submersible performance.
- Gearboxes use special seals and long-life lubricants.
- We design for wide operating temperature ranges and high duty cycles.
Key components and materials we use
- Motor Type: Brushless DC motor for long life and low maintenance.
- Gearbox: Sealed planetary or spur gears with corrosion coatings.
- Feedback Devices: Sealed encoder or potentiometer for precise position control.
- Seals: O-rings gaskets potting compounds and gasketed housings.
- Connectors: IP-rated waterproof connectors and cable glands.
- Housings: Marine-grade stainless steel or anodized aluminum and engineered plastics.
- Cabling: UV and chemical resistant cable with waterproof boots.
We test vibration damping shock resistance and long-term environmental exposure to match MIL-STD and IEC test profiles where required.
Demystifying IP and NEMA ratings
| Rating | Meaning | Typical outdoor use |
|---|---|---|
| IP65 | Dust tight protected from water jets | Outdoor enclosures with occasional cleaning |
| IP66 | Dust tight protected from powerful water jets | Heavy washdown areas |
| IP67 | Dust tight protected from temporary immersion | Solar trackers and irrigation controllers |
| IP68 | Dust tight protected from continuous immersion | ROV manipulators subsea sensors |
| NEMA 4X | Protection from windblown dust rain splashing and corrosion | Marine and industrial gates |
IP67 handles temporary submersion. IP68 can handle continuous immersion at a specified depth and time. NEMA 4X adds corrosion resistance for harsh marine environments.
Performance metrics that matter
When you pick an actuator check these specs:
- Torque (Nm) — match to load and leverage.
- Speed (RPM or deg/sec) — how fast the motion must be.
- Precision & Repeatability — essential for tracking and robotics.
- Duty cycle — continuous vs intermittent operation.
- Voltage & Current — DC or AC power requirements.
- Connectivity — PWM CAN bus RS485 Modbus EtherCAT PROFINET options.
- Power consumption — plan for supply sizing and heat.
- Environmental rating — IP NEMA and temperature range.
We list all these on our product pages so engineers can size parts with confidence. See our actuator controllers page for integration options.

Where waterproof servo actuators shine
- Solar tracking: High uptime and reduced maintenance deliver higher energy yield.
- Marine & subsea: IP68 actuators and pressure compensation for ROVs and AUVs.
- Agriculture: Valves and booms survive fertilizer and washdown.
- Renewable energy: Wind pitch control and solar trackers need precision outdoors.
- Industrial gates & barriers: Heavy duty models resist impact and weather.
- Outdoor robotics: Mobile inspection drones and security robots operate reliably.
- Infrastructure: Traffic systems damper control and surveillance pan/tilt units last longer.
We at Jimi have worked on projects across these fields. We helped a solar farm reach 99.8% uptime with IP67 actuators over five years. We supported deep-sea ROV deployments that ran thousands of hours without ingress failure.
Quick comparison: Sealed feedback types
| Feedback | Strength | Use case |
|---|---|---|
| Sealed Encoder | High precision high speed | Solar tracking ROV manipulators |
| Sealed Potentiometer | Simple robust | Valve position sensing irrigation |
| Absolute Encoder | Retains position on power loss | Safety systems and gate control |
Practical guide to selecting the right actuator
Follow these steps:
- Define the environment: temperature moisture dust chemicals UV exposure and vibration.
- Determine performance: torque speed precision duty cycle and lifespan.
- Check ingress and material compatibility: pick IP or NEMA rating and housing material.
- Plan power and communications: DC vs AC PWM or fieldbus.
- Confirm mounting size weight and bracket needs.
- Consider budget manufacturer reputation and support.
We at Jimi offer product families for each step. Start with our industrial linear actuators and move to custom waterproof builds when you need special torque or submersion capability. (Internal link: browse our Industrial linear actuators)
Installation and maintenance best practices
- Install proper cable glands and sealed connectors.
- Torque mounting bolts to spec to avoid seal distortion.
- Inspect seals and cable entries regularly.
- Replace O-rings and gaskets on preventive maintenance intervals.
- Use recommended lubricants for gearboxes.
- Flush and rinse after exposure to saltwater and reapply corrosion inhibitors.
Simple checks extend service life dramatically. Many customers see 10-year service life in gate and barrier systems when they follow the plan.
Case studies and proven results
