Product Details:

Dual-Circuit Design for Enhanced Safety
The INTORQ BFK464-R brake features a split armature plate and two independent coil circuits, offering redundancy and complying with stringent safety regulations, particularly in passenger elevator systems.
Compact and Economical
Designed to fit into small installation spaces, the BFK464-R's rotor neck only protrudes minimally into the motor bearing shield, while the gear teeth of the rotor are kept short. This makes it an economical choice for space-constrained applications without compromising on performance.
Advanced Noise Suppression and Smooth Switching
The well-engineered damping system ensures low switching noise and a stable braking torque, even on high-temperature contact surfaces. The brake's long-term stable noise suppression is maintenance-free, reducing overall operational costs.
