The RNB-Z series brakes feature a highly compact design, roughly half the size of MNB type brakes, and offers exceptionally high torque. These units were designed for holding and emergency braking, and feature three tapped holes intended for manual screw insertion, that releases the brakes in case of an emergency (SNB series 1.2, RNB series 3 and higher). They offer fast response time due to spring-set design, that enables rapid torque buildup. RNB models are available in two standard voltage options including 90 and 24 V DC, with other non-standard options available on request. Additionally, they offer zero backlash operation due to thin disks, that also eliminate noise, caused by rattling. COMPACT DESIGN WITH HIGH TORQUE The RNB series brakes are approximately one-half the width of MNB style. BASIC DESIGN ADVANTAGE The RNB series brake is designed for holding and emergency braking. MANUAL RELEASE HOLES 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. FAST RESPONSE TIME These brakes are spring-set type brakes, providing rapid torque buildup. OPERATING VOLTAGE OPTIONS RNB units come in two standard voltages, 90VDC and 24VDC. Other non-standard voltages are available. ZERO BACKLASH DESIGN Thin disks in the RNB-Z produce low inertia. A zero backlash design also eliminates any noise due to rattling.
