Dynamixel XW540-T140-R Waterproof Servo Motor

XW540-T140-R: Newcomer to the Dynamixel X Series

Amateur roboticians, researchers and industrial developers are well aware of the advantages of Dynamixel X-Series servo motors. The XW540-T140-R servo motor meets all requirements with its high resolution, high baud rate and multiple programming possibilities..

If you're looking for an ultra-precise robotic accessory that offers detailed feedback and numerous control modes, the X-Series reaches out to you. It brings together a growing number of models with varying degrees of speed or power, with TTL or, like this one, RS485 connections. The X-Waterproof series, a new addition to the manufacturer's already well-stocked range, opens new doors for roboticians looking for aquatic adventures.

Two waterproof models for two categories of torque and speed

Robotis sealed servo motors are available in two models: The XW540-T260-R has a speed of 40 rpm. It is a servo motor with a powerful torque, capable of operating on difficult terrain.

The Dynamixel XW540-T140-R servo motor, on the other hand, is almost twice as fast with less torque. If you want to build a fast exploration machine without a heavy load, you should select this servo motor.

These two servo motors obviously differ in their degree of protection. IP68 corresponds to the maximum protection in terms of dust penetration. Its watertightness level allows it to remain underwater up to 24 hours depending on the depth (between 1 and 3 meters).

Warning

• Do not pull the rubber cap of the connector.
• The rubber cap is connected to the rubber packing, and any deformation may cause leakage. Additionally, the rubber cap is designed for dust protection and is not waterproof. When using underwater, please connect a waterproof cable.
• Dynamixel XW series uses a waterproof cable.
• One side has a waterproof connector and the other side has a JST connector.
• Extension cable has waterproof connectors for both sides
