Submersible Servo, Hitec HSR-M9382TH, 100 meter depth


Digital, waterproof servo, submersible up to 100 meters Programmable rotation up to 7 turns or continuous rotation Brushless motor and magnetic encoder. SKU: SER-1207

Delivery time: 10 - 14 business days


Blue Trail Engineering’s SER-1207 is the ultimate underwater servo for small robotic applications. Unlike any other servo in its class, it can be programmed to provide up to 7 turns of rotation with position control or continuous rotation with speed control. The SER-120X features a brushless motor and magnetic encoder, eliminating the most common causes of servo failure. Ideal for Autonomous Surface Vehicles as well as Remotely Operated Vehicles, the SER-1207 provides reliable, long-term actuation at depths up to 100 meters.


The SER-1207 is based on the Hitec HSR-M9382TH digital servo. Blue Trail integrates a modified HSR-M9382TH into a corrosion-resistant, depth-rated Delrin® housing with a ball-bearing-supported titanium output shaft and nitrile quad-ring shaft seal.
