OCTO Series Multi-head Linear Actuators

The Leader in Linear Motors

Overview

OCTO SERIES MULTI-HEAD LINEAR ACTUATOR

Multi-Headed Linear Positioning Enclosed Stage

PBA Systems introduces OCTO, a multi-headed linear positioning enclosed stage ideal for applications that require independent control of multiple axes travelling on the same directional vector/plane. For further versatility, OCTO actuators provide two independent travel paths/lanes which allow for carriages on different lanes to overtake each other without risk of collision.

Powered by the DX series of ironless motors, the independent carriages are guided by linear encoders and precision recirculation linear ball bearing blocks on a single rail.

Each carriage has its own encoder readhead (Digital and analogue options available) and has a resolution of up to 80nm resolution when analogue encoder option is selected and used in tandem with PBA Maxtune drives --- This allows for extremely precise independent control of individual carriages.

Multiple motors on single travel path
Dual lane operations to allow for overtaking
Custom strokes, and feedback resolution configurations
Effective stroke - Up to 4m (Enclosed version: 2m Max)
Cable carrier attachment
