Motorized Rotation Stage, SR50CC Integrated with CONEX-CC Controller

CONEX-SR50CC is a compact rotation stage integrated with a CONEX-CC controller designed to rotate optical components up to 1-inch diameter, such as polarizers, wave plates, or wedges. The small size allows use in confined spaces, such as laser cavities, disk texturing machines, or manufacturing areas for fiber optical components. SR50CC has a higher resolution (0.001°), better repeatability, and accuracy than PR50CC. The CONEX-CC is a very compact and inexpensive linear driver that has been optimized for Newport’s low power DC servo motor driven devices. Compared to cheaper PWM amplifiers, the CONEX-CC delivers smoother motion with less electrical noise and significantly less motor heating.

The CONEX™ controller comes with a USB cable and a CONEX-PS-CB 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.

Compact Controller and Stage

In terms of size, the CONEX-CC controller is comparable to a deck of cards. Depending on the motor type, up to 3 CONEX-PP or 6 CONEX-CC can fit on a CONEX-BP baseplate. Both controller and stage are compact and ideal for space-confined or access-limited applications. Newport also offers the stand alone version of these Low Profile Rotation Stages.

Scalable Architecture

The CONEX rotation units can be connected via daisy chain to create either multi-axis DC systems or multi-axis PP 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. Additionally, analog and digital inputs can be implemented into the controller through the CONEX-IOD.

Out-of-the-box 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.

Linear Amplifier in DC Units

The low-noise linear amplifier of the CONEX-CC provides the optimum drive solution for low-power DC motors; delivering smoother motion, with less electrical noise and significantly less motor heating.
