The CONEX-URS50BCC is a rotation stage integrated with a CONEX-CC controller. The URS50BCC provides precision 360° continuous motion in a low profile package, compatible with the XM, GTS, ILS, IMS and other linear stages. The stage has adjustable limit switches to prevent over travel. All URS rotation stages feature a proprietary 4-point contact, 2-piece bearing design provides exceptional stiffness, high reliability and outstanding wobble and eccentricity. The flexible preloading system of the worm gear guarantees backlash-free operation.
The CONEX-CC is a very compact and inexpensive, linear driver, 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 the optional CONEX-PS-CB can be purchased for daisy-chaining modules. The CONEX-PS is ordered separately. For OEM applications, an optional retainer to secure the USB and power cables is available.
