LG Unveils Manual & Motorised Rotary Stages

LG Motion has launched a range of manual and motorised rotary stages for precision positioning applications with standard accuracy to 0.1deg and loads up to 500kg. The LGR range covers five models with nominal outside diameter from 82mm to 250mm and a clear aperture (to 110mm diameter on the largest model) to take care of electrical wiring, beamlines or mounted equipment such as optical components and slip ring assemblies.

The smaller LGR0300 and 0400 stages include fine handwheel driven adjustment with a vernier scale for a positioning resolution to within six arc-min and loads up to 5kg. A clamping device is available to lock the turntable. The low-profile aluminium design is supplied with a durable black anodised finish with a selection of base and tabletop M4 or M5 tapped interfacing holes. The LGR1000, 2000 and 3000 series rotary tables are available in a choice of handwheel driven and motorised versions with nominal outside diameters of 88mm, 132mm and 250mm and direct load capacity of 10kg, 50kg and 500kg.

Each model includes a standard positioning accuracy to <0.1deg and repeatability to <0.01deg. Stepper motors or brushed/brushless servo motor drives with optional high-resolution encoders are available along with an inductive datum sensor. The durable design includes a high-specification main bearing and thrust race combined with a smooth 90:1 ratio precision worm and wheel assembly.

Customisation options include directly mounted encoders, hard stops, work holding fixtures and other specialised components. All stages are available with adapter plates for use in multi-axis setups with other rotary stages, or with LG Motion's range of linear positioning stages. LG Motion supports the range with a selection of motion control and drive technologies.

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies

IDEC Corporation announces the PS5R-V line of DIN-rail power supplies, offering their customers high-efficiency in a compact form factor at competitive prices. These power supplies suit a wide range of needs in the industrial marketplace, and carry all of the required certifications necessary for use in these demanding applications. This next generation of the industry standard PS5R power supply family has updated features and specifications to meet current and future needs.

The PS5R-V line of power supplies includes 10W, 15W, 30W, 60W and 120W versions, with additional versions coming soon. These power supplies have a very compact form factor with overall dimensions reduced by up to 25% from previous generations. The reduced form factors combine with DIN-rail mounting to free up valuable control panel space and reduce installation costs.

Operating temperature ranges up to -25 to +75 degrees C offer more versatility. These extended operating temperature ranges often allow these power…
