The Bristol B2 actuator's physical dimensions and technical specifications are located on the drawing below. More detailed drawings are available in our Drawing Download section.
The B2 actuator is available in three standard output travel lengths;
0.5 inch (13 mm), 0.7 inch (17.5 mm), and 1.0 inch (26.6 mm).
In addition, the B2 actuator is available with two types of output shaft configurations;
|
|
|
|
|
|
|
|
|
|
|
Type 1 is a clevis type with an 1/8 pin
 |
|
Type 2 is a 10/32 threaded stud
 |
|
|
|
|
|
|
|
|
|
|
The B2 actuator has internal limit switches that automatically shut off the power at the end of travel. As an option, one or both of these internal limit switches can be wired to output a ground signal when activated. This ground signal can be used to operate a control panel light. An internal linear 5K potentiometer is also an option. Bristol S.G. has many different types of compatible position indicators available in our Accessory Items section.
