Optimal Engineering Systems Releases Clear Aperture Vertical Rotation Stage
Van Nuys, CA — The precision AR59-AV motor- ized, 30 mm (1.2 in.) clear aperture vertical rota- tion stage from Optimal Engineering Systems (OES) contains a 180:1 precision worm drive and deep groove ball bearings for a resolution of ±0.001° when microstepping (10 micro steps-per- step). The parallelism of the table is less than 50 µm. The company designed its AR59-AV vertical rotation stage for use in micro-robotics, metrology, vision systems, positioning of mirrors and lasers, laser machining or scribing, electronic assembly, testing, and photonics. The clear aperture of the vertical rotation
stage allows for both vacuum and electrical lines, as well as optics. A knob on the motor shaft allows for manual positioning. This knob
Phihong: Medical Grade Wall-Plug

including continuous and bi-level positive airway pressure (CPAP and BiPAP) machines, medical imaging equipment, nebulizers, and blood pressure monitors. A limited power source (LPS) with output leakage of less than 100 µA at 264 VAC/50 Hz, the adapter is rated for 110 to 240 VAC input and 12 VDC output. Designated the PMA18A-120 -
PHW, the new adapter is compliant with UL 60601-1 as well as IEC60601- 1-2 Ed4 2014, which addresses electro- magnetic disturbances, requirements, and tests, and IEC60601-1:2005 + A:2012 2xMOPP, which regulates means of patient protection, ensuring a minimum of 4,000 VAC isolation, 8 mm (0.3 in.) creepage, and double insulation. The 18W medical grade wall-plug adapter is also compliant with the latest U.S. De partment of Energy (DOE) Level VI energy effi- ciency standards. The wall-plug adapter has built-
in over-voltage, over-current, short- circuit, over-temperature, and brown- in and brown-out protections. Each adapter measures 43.2 x 82 mm (1.7 x 3.23 in.) and has a 5.5 x 2.1 mm (0.2 x
0.1 in.) fork-and-groove DC plug. Contact: Phihong USA, 47800

may be replaced with an optical encoder for posi- tion verification. The compact black anodized ver- tical rotation stage measures 117 x 80 mm (4.6 x
3.2 in.) and its base is 60 x 60 mm (2.4 x 2.4 in.) for stability, with four countersunk mounting holes for easy integration into new and existing applica- tions. The 59 mm (2.2 in.) diameter table has eight drilled and tapped mounting holes for easy toll mounting, supports loads of up to 1 kg (2.2 lb), and has a scale to clearly display the angle of rotation. Compatible with the company’s line of motion
controllers, the AR59-AV vertical rotation stage is available as a plug-and-play system or with an
optical encoder for position verification. Contact: Optimal Engineering Systems, Inc.,
