Linear Bearings

LM76 (E. Longmeadow, MA) has developed new corrosion resistant linear bearings called Pegasus Series 1 Linear Ball Bearings. Pegasus Series 1 Linear Bearings feature silicon nitride (SiNi) ceramic balls in a shell with retainer and end caps all made from 440 stainless steel and then Armorloy™ coated. Silicon Nitride was selected for the balls because it is: 40% lighter than steel, inert to chemicals, capable of higher speeds and higher loads (RC78 hardness), FDA compliant, and does not corrode or support electrolysis.

Pegasus Linear Bearings are available in two series (closed and open), and in four sizes (1.000”, 1.250”, 1.500” and 2.000”). Dynamic load rating for these bearings are: 220 lbs (1.000”), 352 lbs (1.250”), 490 lbs (1.500”), and 858 lbs (2.000”). Bearings are designed for zero clearance on Class L linear shafting. For maximum performance, LM76 Case Hardened 440 Stainless Steel shafting with Armoloy™ coating is recommended.

PC/104 Embedded Processing Module

Sundance Multiprocessor Technology Ltd. (Chesham, UK) has announced the SMT6657, an embedded processing module manufactured on the PC/104 small form factor of 90 mm × 96 mm. The SMT6657 features two onboard, dual-core TMS320C6657 floating-point DSPs from Texas Instruments based on the TI Keystone multicore architecture. It clocks at 1.25 GHz and generates a raw floating-point performance of 40 GFLOPS (20 GFLOPS per core). The DSPs are closely coupled to an on-board Xilinx Kintex Ultrascale KU35 FPGA used for filtering and post-processing. It also provides the I/O brain of the board, controlling a PC/104 interface, the new PCIe/104 OneBank™ for high-speed connection to a growing range of compatible boards.

PLL Synthesizers

Fairview Microwave's (Lewisville, TX) six new PLL frequency synthesizer models are compact, rugged, SMA-connectorized designs that support USB 2.0 interface with a PC computer supplying DC power and GUI command control. They cover a broad range of frequency bands from 25 MHz to 27 GHz. These models deliver output attenuation that is adjustable up to 50 dB in 1 dB steps and high output power levels ranging from +10 dBm to +19 dBm typical. Phase noise is as low as -108 dBc/Hz at 100 MHz offset and phase locked speed is 1 msec typical.

These synthesizer models also feature a 50 MHz internal frequency source and optional external reference with supplied cable. Frequency resolution can be adjusted using either integer (default) or fractional modes with resolution to a step size down to 1 MHz.

Multi-Axis Robotic Controller

Aerotech's (Pittsburgh, PA) HEX RC is a 6-axis motion controller designed for controlling robotic systems like hexapods. The HEX RC is 4U rack-mountable and compatible with the Automation 3200 (A3200) motion platform. A high-performance processor provides the intense computing power needed to run up to 32 axes; perform complex, synchronized motion trajectories; manipulate I/O; and collect data at high speeds.

The HEX RC features 6-axes of drives capable of controlling any combination of brush, brushless, or stepper motors. It digitally performs both current loop and servo loop closures to ensure the highest level of positioning accuracy and performance. The HEX RC connects and controls up to 26 additional axes of servo, stepper, or piezo-driven stages using the A3200 distributed control architecture. The HEX RC is designed with an ASCII command interface over TCP/IP for control in applications such as beamlines. Alternatively, it can act as a master controller to control other A3200 external drives via the FireWire® interface.

LAN Modules for Power Supplies

TDK-Lambda Americas, Inc. (National City, CA) has introduced LAN (Local Area Network) modules for the popular HFE series of 1600W and 2500W rack mounted, hot swap power supplies. These optional modules allow remote monitoring, status check and programming through a number of standard protocols, supporting VISA (Virtual Instrument Software Architecture). The LAN option is suitable for computer networking, telecommunications, test and measurement and industrial equipment.

The modules plug into any open slot on the standard HFE1600 or HFE2500 19” racks, measuring the same size as the HFE1600 or HFE2500 I2C / PMBus™ equipped power supplies. Removal or insertion of the modules can be made with the AC input applied (to the HFE rack housing, HFE1600-S1U or HFE2500-S1U) without causing any disruption to the power supply output voltage. The HFE1600-LAN and HFE2500-LAN can be used with any of the available HFE output voltages and can support up to two racks, or their individual power supplies. The LAN modules are certified to IEC/EN/UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
