Motorized Actuator, LTA-HS Integrated with CONEX-CC Controller

CONEX-LTA-HS is a high speed motorized actuator integrated with a CONEX-CC controller and is optimized for high-speed applications with a 50 mm travel range. LTA actuators are designed to fit into existing manual stages and other opto-mechanical components as direct replacement for manual micrometers. Features include a non-rotating tip to eliminate wear, and folded motors to minimize the footprint and unwanted cantilevered loads.

The CONEX^™ controller comes with a USB cable and the optional CONEX-PS-CB can be purchased for daisy-chaining modules. Power supply to be ordered separately. For OEM applications, an optional retainer to secure the USB and power cables is available.

LTA DC Servo Actuators

These CONEX kits include either a high speed (LTA-HS) or high load (LTA-HL) DC servo linear actuator. LTA actuators include:

Manual adjustment knob which permits quick positioning of the actuator when the motor is off.
Visible scale that indicates coarse actuator position in both millimeters and inches.
Limit switch that can be manually adjusted.
Non-rotating tip that prevents wear and eliminates periodic motion variations when the actuator is moving.

Compact DC Servo Motion Controller

In terms of size, the CONEX-CC motion controller is comparable to a deck of cards. Up to six CONEX-CC controllers can fit on a CONEX-BP baseplate. Both controller and stage are compact and ideal for space-confined or access-limited applications. The low-noise linear amplifier of the CONEX-CC provides the optimum drive solution for low-power DC motors. It delivers smooth motion, with less electrical noise and significantly less motor heating.

Out-of-the-box PC Control

For out-of-the box control, the CONEX controller is preconfigured and delivered with the motion device. To start moving a sample or sensor, it simply requires plugging in the power supply, connecting the USB communication and starting the free motion GUI. The integrated USB interface, provides a fast ubiquitous communication protocol. For OEM's or security sensitive applications, RS-232 and RS-485 communications are embedded onto the CONEX controller.

Simple Programming with Extensive Language Options

Advanced application programming is simplified by using mnemonic ASCII commands. Newport provides a free GUI that allows the user to access and execute over 60 intuitive ASCII commands. A managed Microsoft .NET assembly (DLL) is provided for programming custom applications in C#, Labview, Matlab, Python and other .NET compatible languages.

Scalable Architecture

CONEX motion controllers can be connected via daisy chain to create multi-axis systems. For added convenience, the power can be shared with up to 5 CONEX-CC modules using the optional CONEX-PS-CB power chain cable. This allows for a convenient low cost multi-axis system.
