The Bristol B3 actuator's physical dimensions and technical specifications are located on the drawing below. More detailed drawings are available in our Drawing Download section.
The B3 actuator is available in only one standard output travel length;
1.2 inch (31.2 mm).
We can make a B3 actuator in any of the B2 standard output travel lengths as a special order for those that prefer a jackscrew type geartrain. Call for details.
The B3 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 B3 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 potentiometer is NOT available in the 1.2 inch (31.2 mm) stroke. Bristol S.G. has many different types of compatible position indicators available in our Accessory Items section.
