A new range of miniature digital linear actuators offers increased mechanical strength and performance with, in many cases, reduced overall size.
Mclennan Servo Supplies has a new range of miniature digital linear actuators that offers increased mechanical strength and performance with, in many cases, reduced overall size.
Smallest in the range with a diameter of just 26mm is the 26DBM series that is available with a choice of magnet technology to optimise price and performance.
When specified with the neodymium magnets the 26DBM provides linear thrusts up to 28N and incremental step sizes down to 0.001in.
The 35DBM series offer similar performance previous types with an overall diameter of 36mm - a reduction of 35% compared with the outgoing models.
The most powerful of the new introductions is the 42DBL series that offers linear thrusts up to 100N from a 42mm-diameter package, resulting in a 14% increase in thrust and a 40% reduction in size compared with previous types.
The DB series digital linear actuators are stepper motors that incorporate an internal leadscrew to convert rotary to linear motion.
The units are available as four-phase unipolar or two-phase bipolar types and offer a choice of stroke lengths from 13 to 260mm and a choice of resolution from 0.025 to 0.05mm per step.
The DB series linear actuators are ideal for use with digital control techniques in applications such as ball valve actuation, scientific medical and optical equipment and light duty industrial control and manipulation systems.
