Rexroth expands line of vacuum non-contact transfer units

The Non-Contact Transfer (NCT) unit from Rexroth is a unique picking device that operates on the Bernoulli principle, which applies airflow under the device to create a vacuum and lift force between the center and circumference. The line is now expanded to include a high-grade polymer version.

In the last few years, the NCT transfer system has solved many customer problems associated with how to effectively handle materials that are porous, delicate, or have rough or soft surfaces. Now, in addition to the standard aluminum version, the NCT is available in PEEK (Polyetheretherketone), a high-grade polymer. The material expands the potential applications of the NCT to areas where aluminum components are not suitable. Resistance to chemicals, conventional solvents, acids, salts and oil are properties that make this new version of the NCT an ideal handling component for both the packaging and food/beverage industries. FDA- and EG-approved materials guarantee the safe use of these components, even in direct contact with food products. A low friction coefficient and high resistance to wear ensure a long service life and hygienic handling.

The Rexroth NCT unit provides a solution to handling challenges where suction cups are not feasible because good contact cannot be made with an object’s surface. Another advantage of the NCT is that a machine with mechanical grippers can be easily converted to the NCT, since it does not require a vacuum generator, unlike other devices that operate using vacuum pressure. The NCT series is available in four sizes accommodating lift capacities up to 2 lb (0.9 kg) each, and multiple NCTs can be used together for lifting larger weights.

Pneumatic Valve Fieldbus Protocol with Sercos III and Ethernet/IP

The expansion of B-Design fieldbus components includes support for Sercos III and Ethernet/IP for valve manifold systems Series HF03-LG, HF04, and CD01/02-PI. The valves include body sizes with 10, 15, 18 and 26 mm widths. All electric pneumatic, supply and exhaust connections are on one plane for clean installation. Discrete output modules control up to 2 A current draw per point, and modular expansion of discrete and solenoid outputs is possible.

The Sercos III version features up to 32 outputs per valve manifold and up to four valve manifolds can be controlled from one bus module.

The EtherNet/IP version features up to 48 inputs per valve manifold in addition to solenoid and discrete outputs, and up to four valve manifolds can be controlled by one bus module. The standard module works with EtherNet/IP, Modbus TCP and TCP/IP protocols.
