OverviewThe power-fail (operating current) electromagnetic brake COMBINORM B releases when the supply voltage is removed. It is intended for precise positioning and reliable holding and is used in safety and access technology, for example in access barriers or fire doors. The brake is designed for continuous operation (S1) and can be supplied with optional VdS approval. Torque range: 0.5 Nm to 1,250 Nm.
