Operating VoltageOptions. Spring applied holding brake designed for general industrial applications. Unit is used for holding only. Very thin brake profile provides a compact package. Braking force is produced via springs so basic fluctuations in voltage and temperature have no effect on the brake. Long life friction material allows for many trouble free cycles. Standard voltages are 24 and 90 volts. Other voltage options are available. Compact DesignWithHigh Torque. The RNB series brakes are approximately one-half the width of MNB style. Manual Release Holes. Basic DesignAdvantage. These brakes are spring-set type brakes, providing rapid torque buildup. The RNB series brake is designed for holding and emergency braking. Compact DesignWithHigh Torque. Fast Response Time. The RNB series brakes are approximately one-half the width of MNB style. Starting with SNB series 1.2 and RNB series 3 and higher all units have three tapped holes in which screws can be inserted for manually releasing the brake in case of emergency. RNB units come in two standard voltages, 90VDC and 24VDC. Other non-standard voltages are available.
