This is the S-type model of the BXW series, designed exclusively for holding, which offers three load torque variations within the same dimensions. It is part of a compact lineup known as the "micro size" among non-excited holding brakes. This brake is designed solely to hold machinery in a stationary state; while it offers high holding torque, it cannot be used for emergency braking.
