Rotary limit Switches series Driver FRM


Rotary limit switches series Driver FRM are projected and manufactured to offer a very flexible solution which can be customised according to our customer’s requests.
They are equipped with 3 internal rotation axes, which create simultaneously their own, even independent ratios.
The series ranges ratios from 1:1 to 1:900 and a series of optional sensors mounted inside.
Internal switches are finger-proof, rapid positive-opening, snap for your safety and can be either 1NO 1NC or simultaneously independent.
The security limit switches Series Driver FRM, already used for yaw and pitch control on wind turbines for the production of renewable wind power, positively went through the qualifying examination for corrosion and salt spray – according to EN ISO 9227:2006, as well as for resistance to humidity – according to ISO 6270. Thanks to this achievement the product can be safely applied on offshore wind turbines as well.

The Ravioli KST absolute single turn sensor is now available upon request. Thanks to its capability in valuing and recording a value for each position in the 360° rotation, this sensor is your perfect ally in applications in industrial opening systems, such as speedy-doors, folding-doors, gates, sectional doors and automation devices by and large.
