BRISTOL S.G. B2 SERIES MINIATURE LINEAR ACTUATORS

The B2 actuator is a small 12-14 Volt DC linear actuator featuring internal travel limiting switches. When activated, the B2 actuator will continue to run until the power is turned off or until it automatically shuts off at the end of its travel. It can also be stopped in any position by switching off the power. Since the thrust is generated by means of a jackshaft, the output shaft will lock in any position when the power is off. Voltage polarity determines the direction of travel.

The B2 actuator features an internal, electronically isolated, 0-5K ohm linear potentiometer to measure the position of the output shaft. Bristol SG has compatible position indicators available in our Accessory Items section. The B2 actuator can be ordered without this internal potentiometer and can be further modified to send a ground signal when the internal limit switches are activated. Please call for details.

The B2 actuator is designed to work with our C1 series clevis. It shares the same footprint as our B6 actuator. The B2 actuator is available in 0.7 inch (18 mm) travel. It can be special ordered in 0.5 inch (13 mm) and 1 inch (26 mm) travels. Please call for details.
