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. These brakes are spring-set type brakes, providing rapid torque buildup. Manual Release Holes. TwoBasic DesignsAvailable. The SNB series are designed for stopping and holding. Longevity. Fast Response Time. SNB units come in two standard voltages, 90VDC and 24VDC. Other non-standard voltages are available. The use of wear-resistant frictionmaterial provides extended operational life. Compact DesignWithHigh Torque. Spring applied holding brake designed for general industrial applications. Unit is used for both stopping and/or holding. 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. The SNB series brakes are approximately one-half the width of MNB style.
