20kg.cm Copper Gear High-Torque 180° Digital Servo

The WP5320 is a high-performance 180° copper gear, 20kg.cm, IP54 waterproof and dustproof digital servo with dual ball bearings.

The high torque servo operates between 4-8.4V with a no load current of 120mA and locked rotor current of 3A at 7.4V, with a KT rating (torque per amp of current) of 6.5kg.cm/A.

It's a 180° servo, controlled via PWM (pulse width modulation - 500μsec to 2500μsec) with a mechanically unlimited angle, using a standard 3-pin output for GND, VCC and PWM. It can be controlled with various servo drivers such as this 16-Channel HAT from Waveshare.

The servo also features an electronic protection function, which can automatically output protection torque during stalling, effectively protecting the safe operation of the servo and the system.

A set of servo horns and fixings are included in the package. We also stock a 35kg.cm version with all-steel gears.
