NA Series NEMA Linear Actuators

  • Manufactured by: Zaber Technologies

Quick Overview

These linear actuators based on standard Nema stepper motors offer finer resolution, higher thrust, higher speed, and longer lifetime when compared our T-LA series of linear actuators. The actuators include 30cm of cable wired to a mini-din 8 connector for use with our T-CD series Chopper Drive controller (shown above driving an NA11B-30 actuato..

Description

These linear actuators based on standard Nema stepper motors offer finer resolution, higher thrust, higher speed, and longer lifetime when compared our T-LA series of linear actuators. The actuators include 30cm of cable wired to a mini-din 8 connector for use with our T-CD series Chopper Drive controller (shown above driving an NA11B-30 actuator) which must be purchased separately. The actuators have a built in magnetic home sensor. In addition to the listed actuators, we have larger Nema size 17 and 23 actuators available in the same ranges of travel. Size 23 offers up to 200 lb force. We are in the process of adding these to our website. In the meantime, please contact us for more details if you are interested in higher thrust.

 

When used with our T-CD series Chopper Drive controller as shown at right, these actuators achieve resolutions down to 0.05 µm, with travels up to 60 mm travel. Controllers can be daisy chained with each other and all Zaber T-series products, to a single serial or usb port.



To control actuator position, simply transmit the unit number of the actuator you want to move, a simple move command and the position desired. After the move, the controller will report its position. For a detailed list of available commands see the user's manual.



A knob at the end of the controller permits smooth manual control. Knob position controls actuator velocity. During a manual move the actuator constantly transmits its position so the controlling computer can track it.

Manufacturer Informations

Zaber Technologies
Manufacturer Website

    Zaber was founded in 1997, when precision linear actuators all used DC motors with gearboxes and encoders requiring bulky controllers.
    Zaber resolved this by integrating the motor, controller, driver, and mechanics into a single device with a small form factor.
