Festo
8087821
Rotary drive unit ERMS-32-90-ST-M-H1-PLK-AA
The Festo 8087821 is an electromechanical rotary actuator of size 32 featuring an integrated actuator and gearbox with a 7:1 gear ratio. Weighing 2304 g with a 100% duty cycle, this component delivers a max rotational speed of 100 rpm, a torsional backlash of 0.2 deg, and a repetition accuracy of ±0.1° via a motor encoder for position sensing. It supports any mounting position with internal thread mounting and accommodates a max axial force of 450 N, a max radial force of 550 N, and a permissible mass moment of inertia of 0.0164 kgm² with a 1.8 deg step angle and ±5% step angle tolerance. Power is supplied through a 4-pin M12x1 plug utilizing T-coded connection technology as per EN 61076-2-111, alongside a plug-type logic interface.
