Festo
8087820
Rotary drive unit ERMS-25-180-ST-M-H1-PLK-AA
The Festo 8087820 is an electromechanical rotary actuator featuring an integrated actuator and gearbox in a size 25 format with any mounting position and internal thread mounting. This unit delivers a 9:1 gear ratio, a maximum rotational speed of 150 rpm, a 0.2-degree torsional backlash, a repetition accuracy of ±0.05°, and a 1.8-degree full step angle with a ±5% tolerance. Operating at a 100% duty cycle, it supports a maximum axial force of 350 N, a maximum radial force of 450 N, a permissible mass moment of inertia of 0.0065 kgm², and weighs 1472 g with a motor encoder for position sensing. Power connections utilize an M12x1, T-coded 4-pin plug conforming to EN 61076-2-111, paired with a plug-type logic interface.
