Mounting Clamps

J.W. Winco, Inc. (New Berlin, WI) announced the GN 784 metric size, aluminum mounting clamps with swivel ball joint. The clamps, which are RoHS compliant, allow precise and variable adjustment of the ball pivot within the rotation range. They can be mounted from below via the internal thread, or mounted with the company’s GN 784.1 flange using three through-holes from above. The housing is aluminum with a black anodized finish, while the base plate and ball are aluminum with a plain finish. An adjustable hand lever is zinc die cast, powder coated in silver with a textured finish. The threaded stud, retaining screw, and set screw are stainless steel.

Electric Linear Module

The ELP electric linear module from SCHUNK (Morrisville, NC) comes with direct drive and an integrated controller. It is scope-free guided using a pre-loaded roller guide, and can be adjusted in two steps. The end positions are mechanically adjusted with a screw, and the speed of extension and retraction is adjusted using rotary switches on the side of the unit. Speed can be automatically adjusted, depending on extension weight, and no shock absorber adjustment is necessary because the drive automatically regulates the brake process. The control and power electronics are directly integrated into the module, and can be controlled by a Fieldbus distributor or through digital signals.

6-Axis Robots

TM Robotics (Elk Grove Village, IL) offers three models of its TVM 6-axis robots. The robots are compatible with other Toshiba Machine products, including its injection molding machines and machine tools. The TVM is a vertically articulated robot series aimed at a multitude of industries. The three models of the TVM are: TVM900/TSL3200E with a 1124 mm reach and 20 kg payload, TVM1200/TSL3200E with a 1418 mm reach and 15 kg payload, and TVM1500/TSL3200E with a 1715 mm reach and 10 kg payload. Combined with the company’s robot vision recognition package, TSVision3D, the TVM supports implementation of bin-picking automation.

Modular PLC

Delta Americas (Raleigh, NC) announced the AS300 Series compact programmable logic controller (PLC). The modular PLC features integrated 6-axis motion control via pulse control (200 kHz or 4 MHz), and built-in encoder feedback. Up to eight of the company’s ASDA-A2 Series servos can be controlled with the addition of a CANopen network module. The rack-less design includes the company’s “Slide-Lock” feature for connection and expansion without moving other modules. A 32-bit CPU provides execution speed of 40k steps/ms, and supports up to 32 extension modules or up to 1,024 outputs. The AS300 includes a built-in Ethernet port, SMTP email server connectivity for alarm notification, an integrated light-webserver, and direct database connectivity via the eServer tool. It provides multi-layer password protection and includes a Micro SD card with up to 32 GB of additional storage.

Angle Sensors

Novotechnik, U.S. (Southborough, MA) introduced the RFC4800 series of touchless rotary angle sensors that provide absolute rotary position. Partial and fully redundant versions are ISO pulses and ISO 11452 tested for safety and mission-critical applications. The sensors use a magnetic pickup to provide a touchless measurement range of 0 to 360°, and make measurements through air and non-magnetic materials. A magnetic pickup mounts to a shaft on the target design, with seven different size markers available. Features include ingress protection from liquids and dust to the IP 69K standard, resolution of 14 bits, repeatability of 0.36°, and independent linearity of ±0.5%. Analog and digital output versions are available that include CANOpen and IO-Link.

Planar Gantry

Festo (Hauppauge, NY) expanded its line of planar gantries with two larger models, the EXCM-30 and EXCM-40. The EXCM series provides two- or three-axis Cartesian motion for benchtop assembly machines and medical laboratory devices. The units can be installed directly on a worktable without an external control cabinet. The EXCM-30 has a clean look housing, and the cover of the Y-axis provides basic protection against the ingress and discharge of particles. The Y-stroke can be expanded to 16, 18, and 20 inches (410, 460, and 510 mm). The EXCM-40 has a larger working area of up to 78 inches (2000 mm) in the X direction and 39 inches (1000 mm) in the Y direction. A 48-V power supply can dynamically handle loads of up to 8.8 pounds (4 kg). A controller package consisting of two motors and a CMXH controller is available for both versions.

Compact Air Cylinders

Bimba (Monee, IL) introduced the Flat-1® compact air cylinders with 19 new product enhancements, such as permanent grease lubrication, an improved bumper design, and hard chrome-plated piston rods with an option for stainless steel. The cylinders are available in eight bore sizes, and are rated for 3,000 miles of travel with L Option seals. Additional options include thick-walled aluminum and composite cylinder bodies, low pressure hydraulic designs, metallic scrapers, magnetic reed switch compatibility, and a standard mounting hole interchange for another compact cylinder manufacturer. Single acting spring return cylinders include rod seals to provide for standard fail safe operation.

Spring Engaged Tooth Brakes

SEPAC Inc. (Elmira, NY) offers the SETB electromagnetic spring engaged tooth brake for medical applications. This power off brake has less than 0.5° of backlash within the brake once properly installed, and has a high number of index positions. Its high-temperature, Class H insulation, fully potted coil is rated for 180 °C. The brake typically offers a 2:1 reduction in size when compared to a friction-style brake with similar torque ratings. The lead wires can also be routed through the bore or the rear of the magnet body. Custom bore sizes are available, and each brake is virtually maintenance-free under proper operating conditions.

Fluid Transfer Pump

Fluid Metering, Inc. (Syosset, NY) offers the valveless Fluid Transfer Pump that integrates the company’s CeramPump® pumping technology with a brushless DC motor and integral driver electronics to provide precision fluid control for process instrumentation. CeramPump valveless fluid control technology utilizes one moving part — a rotating and reciprocating ceramic piston — to accomplish all fluid control functions within the pump, thereby eliminating the need for the check valves typical of reciprocating pump designs. One complete piston revolution is required for each suction/discharge cycle. The sapphire-hard, dimensionally stable ceramic internal components have high accuracy that is not dependent on the memory and integrity of flexible tubing.
