What Is the Operating Temperature Range for PA Linear Actuators?
PA linear actuators are rated for use across a specific temperature range. Operating outside this range reduces performance, accelerates wear, and can cause permanent damage to motor windings, lubricants, and plastic components.
Temperature Ratings by Series
| Actuator Series | Operating Temp | Storage Temp | Notes |
|---|---|---|---|
| PA-14 / PA-04 / PA-03 | –26 °C to +65 °C | –40 °C to +85 °C | Standard indoor/outdoor range |
| PA-12 (mini) | 0 °C to +40 °C | –10 °C to +60 °C | Indoor applications recommended |
| PA-17 (industrial) | –26 °C to +65 °C | –40 °C to +85 °C | IP54 rated, suitable for outdoor use |
| PA-10 (IP68M) | –26 °C to +65 °C | –40 °C to +85 °C | Marine grade, designed for submersion |
⚠️ Always verify with your model's datasheet Temperature specs vary between models and production runs. Download your model's datasheet from the PA Resources page for the authoritative specification.
Cold Weather Considerations
- Grease viscosity increases— At temperatures below –10 °C, grease in the gearbox thickens, increasing drag. Expect reduced speed and increased current draw in cold starts.
- Reduced battery/PSU voltage— In outdoor battery-powered systems, cold reduces available battery voltage. Ensure your power supply's minimum voltage output covers the actuator's minimum operating voltage.
- Condensation risk— Bringing a cold actuator indoors causes condensation. For non-IP-rated models, allow the actuator to reach ambient temperature before operating to prevent moisture ingress.
High Temperature Considerations
- Motor heat + ambient heat stacks— Self-generated motor heat adds to ambient temperature. In hot environments, reduce duty cycle to allow extra cooling time.
- Seal expansion— At sustained temperatures above 60 °C, rubber seals can soften and may not provide the rated IP sealing. Shade the actuator or use active cooling in extreme environments.
