MDR845WP Servo
SKU:
Hitec's MDR845WP multi-rotation industrial actuator offers a wide voltage range, as well as IP67-certified water & dust-proof protection, making it suitable for many industrial applications. Featuring a machined aluminum-composite case to dissipate heat, two ball bearings and four steel gears, digital amp with MOSFET drive, and both PWM & PWM/TTL control protocols, this powerhouse delivers nearly 700 oz-inches of torque! You can program parameters such as End Point Adjustments, Direction, Speed and Fail-Safe position to optimize the installation and performance when your industrial applications demand that extra level of performance and capability.
How Far Will This Servo Rotate?
The answer to this question is partially dependent on what you are using to control the servo.
Click for a quick video explanation.
With an Average Radio System:
7.46 Turns (2686°)
Your average transmitter and receiver will output a relatively narrow PWM signal range.
Radio System + Travel Tuner:
10.8 Turns (3880°)
Adding a Servo Travel Tuner to your radio system setup will allow you to achieve wide PWM signal ranges.
Wide Signal Controllers:
10.8 Turns (3880°)
Controllers such as the Servo Commander, Arduinos, and Raspberry Pi servo hats can usually send a wide signal.
