Festo
2954695
Rotary actuator ERMO-12
The Festo 2954695 is an electromechanical rotary actuator of size 12 featuring an integrated gearbox with a 9:1 gear ratio and infinite rotation angle. Weighing 475 g, it delivers a nominal torque of 0.15 Nm, a nominal rotary speed of 100 rpm, a maximum speed of 200 rpm at 90°, and operates at a 100% duty cycle with any mounting position utilizing internal threads. Technical parameters include a 1.8 degree step angle with a ±5% tolerance, 0.2 deg torsional backlash, ±0.05° repetition accuracy, 0.0003 kgm² permissible mass moment of inertia, 0.0079 kgcm² mass moment of inertia JO, 2E-05 J impact energy in the end positions, 180 N max. axial force, and 200 N max. radial force.

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.
