Product catalog summary

Introduction
Founded in 1926 in Milan, Ravioli S.p.a has over 80 years of experience in manufacturing electronic and electro-mechanical devices. The company has developed a significant production line focused on alternative energies, particularly wind power technology.

Rotary Limit Switches for Wind Turbines
Ravioli S.p.a offers a series of rotary limit switches specifically designed for pitch and yaw control in wind turbines. These switches, known as DRIVER FRM, are IP66 rated and can be equipped with various cam profiles for precise, rapid, and reliable calibration.

Pitch Control
The pitch control system allows the angle of the blades to vary according to wind directions, maximizing turbine efficiency. Rotary limit switches set reliable and safe margins for blade motion, regulate their angle, and provide real-time position indications through high-precision encoder signals.

Yaw Control
The yaw control system ensures the rotor remains perpendicular to the wind, reducing fatigue loads and optimizing power. Rotary limit switches prevent cable twisting and limit turbine rotation, while high-performing encoders deliver precise yaw position signals.

Additional Offerings
The product line is complemented by various accessories and options for custom solutions, as well as a series of d.c. contactors called Tecno, used in inverters and other industrial devices for energy storage.
