Features waterproof IP67 rating for moisture protection
Includes a durable gear system with metal and steel
Ensures precise control with 2μs deadband
The Hitec D840MW 32bit Waterproof Multi-Purpose Mega Servo (Mega 15 Spline) is a versatile and robust servo designed for a wide range of applications. It operates efficiently across a voltage range of 3.5 to 8.4 volts, making it adaptable to various power sources. The servo is engineered to deliver impressive performance with a no-load speed that varies with voltage, ensuring quick and responsive operation. Its stall torque is substantial, providing the necessary force for demanding tasks, while the peak efficiency torque ensures optimal performance under load.
Constructed with durability in mind, the servo features a combination of engineering plastic and an aluminum heat sink for the case material, which aids in heat dissipation and enhances longevity. The gear system is composed of a mix of metal, plastic, and steel gears, ensuring strength and reliability in operation. The motor type is a cored carbon brush, and the servo is equipped with two ball bearings, contributing to its smooth and efficient functionality.
The servo's IP67 rating signifies its waterproof capabilities, making it suitable for use in environments where exposure to moisture is a concern. The analog controller amplifier type ensures precise control, and the deadband of 2μs allows for accurate positioning. The connector wire is 300mm in length and uses a 20AWG gauge, providing flexibility and ease of installation.
Note: Ensure proper handling and installation to maintain the waterproof integrity and performance of the servo.
