26DBM-K Permanent Magnet Stepper Digital Linear Actuator

Permanent Magnet Stepper Digital Linear Actuator

div class="field field-name-field-solution-info field-type-text-long field-label-hidden">

The 26DBM-K is a captive linear actuator that provides up to 128 oz of linear force in a 26 mm frame size. The 7.5 degree step angle and .0005" lead screw pitch option allows for greater positional resolution. Mclennan holds stock of various configurations in the UK for immediate delivery. For technical assistance and details of value added assemblies, including gearboxes and wiring / connector options please contact our sales and applications support team.

Motor Highlights

High continuous linear force output for size
Digitally controlled - easy to use with a micro processor
Cost effective - compact design, lower integration cost
Maintenance free - no brushes to replace
Unipolar and bipolar winding options
Captive and non-captive designs
Long life - ball bearing design

Customization Available

Coil modifications - resistance and inductance
Magnets - to yield higher linear force or reduced detent levels
Higher strength plastics for higher impact forces
Reduced or increased detent force to suit the application
Screw - metric or imperial tips, length
Special flanges, connectors, end of motion detection sensors
Wire harness - connectors, pins, lead length, shrink tubing

Applications

Infusion Systems
Pipettes
Damper Actuation
Flap actuation
Printers and copiers
Switching systems
