Basic DesignAdvantage. Fast Response Time. 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. Compact DesignWithHigh Torque. Spring applied holding brake designed for general industrial applications. Unit is used for holding only and has special zero backlash armature. 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 frictionmaterial allows for many trouble free cycles. Standard voltages are 24 and 90 volts. Other voltage options are available. The RNB series brakes are approximately one-half the width of MNB style. The RNB series brake is designed for holding and emergency braking. These brakes are spring-set type brakes, providing rapid torque buildup. RNB units come in two standard voltages, 90 VDC and 24 VDC. Other non-standard voltages are available. Operating VoltageOptions. Manual Release Holes. Zero Backlash Design. Thin disks in the RNB-Z produce low inertia.Azero backlash design also eliminates any noise due to rattling.
