Etronix ET0025 25kg-0.20s Waterproof Metal Gear Servo

The Etronix ES025 (ref. ET0025) is a standard-sized digital servo motor designed for RC installations requiring high torque. Its metal gear transmission, two ball bearings, and sealed design make it suitable for radio-controlled models using a servo with standard dimensions of 40 x 20 x 40 mm.

An RC servo transforms commands sent by the receiver into precise mechanical movement. It is used, in particular, to steer a radio-controlled car, steer a boat, or control a moving part on a model. Digital technology handles the electronic processing of positioning commands, while the available torque allows the servo to hold and move a control subjected to force.

The ES025 operates from 4.8 to 8.4 V and offers performance that varies with the supply voltage. Its holding torque is 22 kg.cm at 4.8 V, 25 kg.cm at 6.0 V, 28 kg.cm at 7.4 V, and 30 kg.cm at 8.4 V. Its operating speed reaches 0.22 s/60° at 4.8 V, 0.20 s/60° at 6.0 V, 0.18 s/60° at 7.4 V, and 0.16 s/60° at 8.4 V.

This Etronix servo features a DC motor, a plastic housing, and a 25T splined output. The servo arm or control horn used must therefore be designed for a 25-tooth spline. Its operating frequency is 330 Hz with a pulse width of 1520 µs, and its dead zone is specified at 3 µs.

With its standard size, the Etronix ES025 can be integrated into models with a servo bay compatible with its dimensions. Its 240 mm connecting cable facilitates connection to the receiver or a servo extension when the electronics setup requires it.
