Air Compressor

Gardner Denver Thomas (Sheboygan, WI) offers the 2380 series twin WOB-L® piston oil-less air compressor designed for pressure/vacuum and high flow. It provides 100 psi (6.9 bar) maximum pressure with open flow of 2.3 cfm (65 l/min). The air compressor is fan-cooled and has a one-piece monolithic head. Weighing 12 pounds, it is 9.31" (236.5 mm) long × 5.14" (130.6 mm) wide × 6.73" (171 mm) high. The twin-cylinder design helps provide reliability, low vibration, and quiet operation.

High-Speed Backplane Connector System

Samtec (New Albany, IN) has expanded its ExaMAX® High-Speed Backplane Connector System optimized for high-density and high-speed performance. The ExaMAX® header and right-angle receptacle system (EBTM/EBTF-RA Series) is optimized for speeds up to 28 Gbps on a 2.00 mm column pitch or 56 Gbps on a 3.00 mm column pitch. For 28 Gbps performance, this system meets and exceeds OIF-CEI-28G-LR specifications. Return loss compliance is achieved in both 85 Ω and 100 Ω systems due to targeting the 92 Ω specifications and controlling reflections at all geometry transitions within the connector.

Magnetic Encoders

POSITAL (Hamilton, NJ) introduced new models of IXARC magnetic encoders that combine incremental and absolute rotation measurement capabilities in a single, compact package. Absolute encoders provide a control system with a report of the rotational angle and rotation count at a specific point in time; incremental encoders provide a signal pulse each time the encoder shaft rotates by a specified angle. The hybrid encoders are based on the company’s magnetic measurement technology, and offer shock, dust, and moisture resistance. The hybrid incremental and absolute rotary encoders have communications interfaces that support both measurement modes: RS-422, HTL, or TTL for incremental readings; and SSI for absolute measurements. Available multi-turn versions can count up to 64,000 revolutions, while incremental measurements have resolutions as high as 16,384 pulses per revolution.

Planetary Gearbox

GAM (Mount Prospect, IL) offers the SPH inline planetary gearbox with helical gears for dynamic and cyclic applications, as well highspeed and continuous duty applications. It is available in six frame sizes with nominal torque ratings from 15 to 900 Nm. The face width of the gears provides more tooth contact and greater overall torque density. The gears are case-hardened, which imparts strength deeper into the gear. With several output configurations available, machine integration is simplified.

Clutches

U.S. Tsubaki Power Transmission, LLC (Wheeling, IL) announced Cam Clutch unidirectional/ mechanical clutches that lock the inner and outer races through the locking action of cams, transmitting torque in one direction of rotation while overrunning in the other. The cams are made of alloy steel, and the races are made of alloy steel with high surface hardness and core toughness. They are precision-ground to provide concentricity and surface finish for accurate cam rotation.

Electric Cylinder

SMAC (Carlsbad, CA) introduced the CBL50 electric cylinder designed to achieve peak force of 50N at 2 Amp current, and acceleration up to 40G. It features carriage-free design and built-in linear bearings. It is available with a vacuum and spring option for pick-and-place applications. With the optional IP65 and IP67 dustproof and waterproof feature, the cylinder is suited for applications such as food and beverage processing, packaging, and pharmaceutical industries. Stroke lengths of 10, 25, 50, and 100 mm will be available. The cylinder is offered with a choice of encoder resolutions, with 5-micron standard, and 1 and 0.1 micron optional. It is fully programmable in position, velocity, and force simultaneously. A patented “Soft-land” function ensures precise contact force.

Stages

Optimal Engineering Systems (Van Nuys, CA) released low-profile XYθ (theta) stages that move in an XY-plane and rotate around the center of the XY-plane. Available in 12 models in two precision grades, the stages have linear travels from ±2 by ±2 mm, up to ±30 by ±30 mm. The stages can rotate around the center of the XY plane up to ±6°. Four models have solid tables sized from 100 x 100 mm to 200 x 200 mm, and eight stages from 250 x 250 mm to 1500 x 1500 mm are hollow core (open frame) stages. Available in normal and precision grades, they have preloaded cross roller bearings, and typical normal repeated positioning accuracy is from ±1.75 μm to ±2.5 μm; typical precision repeated positioning accuracy is from ±0.7 μm to ±1.0 μm.

Parallelism of the stages is as low as 30 μm, and the larger stages can handle dynamic loads to 600 kg. The stages can be ordered with linear encoders for closed loop operation, customized to meet specific requirements, and complete ready-to-run alignment systems.
