The Lenze E340765-7231V30 is a genuine replacement brake coil specifically designed for use with the Lenze BFK458 series of spring-applied brakes, most commonly the BFK458-14 model. This essential component is responsible for energizing the electromagnetic field that releases the brake, allowing the connected motor shaft to rotate freely. When power is removed, the coil de-energizes, and the brake’s springs engage to provide reliable and safe stopping power. As an original Lenze part, it guarantees perfect compatibility, optimal performance, and the long-term reliability required for demanding industrial applications.
