Alnico 3B Relay - Speed Sensor with Snap Switch
Relay type 3B - manufactured by Fabryka Obrabiarek RAFAMET S.A. - together with the protection system, performs as a speed sensor and has a magnetically coupled snap switch that switches on depending on the rotational speed. It is adapted to both right and left rotations. Often used to indicate increasing or decreasing rotational speed.
Together with the Anico 3B protection system, it serves as a sensor for quick braking of electric drives, using the so-called countercurrent braking. Often used in cranes and other lifting devices.
