Festo
8087819
Rotary drive unit ERMS-25-90-ST-M-H1-PLK-AA
The Festo size 25 electromechanical rotary actuator features an integrated gearbox with a 9:1 gear ratio, a motor encoder for position sensing, and an internal thread mounting design that supports any mounting position. Weighing 1472 g, this component delivers a max rotational speed of 150 rpm, 0.2 deg torsional backlash, ±0.05° repetition accuracy, 350 N max axial force, 450 N max radial force, and a 100% duty cycle with a 1.8 deg full step angle. Electrical connection is facilitated through an M12x1, T-coded plug power supply with 4 pins, alongside a separate logic interface plug.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
