SERIES DESCRIPTION

The Warner Electric FB Series Electrically Released Brakes utilize permanent magnet technology to provide reliable, fail-safe braking. The brake remains engaged until the specific DC voltage is applied to the electromagnetic coil, creating an opposing magnetic field that releases the armature.

The 5391-170-012 is an FB-475 model size configured for 24 VDC operation with a 1-inch bore. This unit provides significant holding power in a compact, shaft-mounted package, making it ideal for 24V industrial automation and mobile equipment.

Key Features

  • 24V Low Voltage Design: Safely integrates with PLC and modern DC-bus industrial control systems.
  • Autogap™ Technology: Automatically maintains the proper air gap as friction surfaces wear, ensuring consistent performance without manual adjustment.
  • Fail-Safe Protection: Instant engagement upon power loss ensures the load is held securely in position.
  • Segmented Armature: Allows for superior heat dissipation, extending service life in high-cycle applications.

Technical Alert
This is a 24V DC component. Applying 90V to this unit will cause immediate and permanent coil failure. Ensure your power supply is regulated to the correct voltage before installation.
