There are several popular 12V dc small electric actuators and 24V electric actuators in this product line. These include a light duty linear actuator or the DLA1 series 12V actuators. The others are heavy duty linear actuators such as the DLA2 series and DLA3 series 12V actuators. All these linear actuators 12v waterproof have a high IP66 rating which protects them from water and dust. This makes them suitable for use in harsh conditions. The DLA3 can be especially used as heavy duty industrial linear actuators as they could push up to 15000N force. It’s the most rugged actuator and built to perform well in all kinds of harsh environment and require almost no maintenance.
