A new series of brakes from INTORQ with IP65 enclosure offers a  solution for stopping and holding duties in damp or dirty environments.  The series BFK461 are spring-applied brakes released by applying DC voltage to an electromagnetic coil. 

Brakes can be engaged dynamically at motor speeds and also suit static holding applications. 

The BFK461 brakes are constructed with an aluminium casing and O-ring to seal the connection to the mounting surface. A plastic cap and seal close the central bore, and the supplied fixing screws have seals under the heads.
