Brake AB 28 24 VDC, 0.4 Nm
Important Information • Permanent magnet — single-face brake for DC (dry operation). Braking in unpowered condition. • Holding brake, prevents rotation of the shaft at standstill or with turned off motor power. • Not suitable for dynamic braking. • It is possible to lower the voltage applied to the brake after it has been energized, for the purpose of reducing heat loss. • Schematic image: does not necessarily reflect the delivery state.
