Eurotech implements standardised and customised handling and transport solutions in the field of vacuum technology. With three brand new products, Eurotech will demonstrate its competence at the international trade fair for sheet metal processing, the Blechexpo, from November 5 to 8. In addition to a new eT-Hover-panel series lifting device for removal of narrow high-bay drawer racks, the vacuum specialist has expanded its product portfolio with other eT-Hover-modesty series lifting devices. Another focus of this year’s Blechexpo will be the electronic handheld suction device, type Nemo, which will also be available for testing.
Blechexpo visitors can see and test the new products and solutions, specialised for the sheet metal processing industry, in Hall 3, Booth 3412. The vacuum lifting devices of the eT-Hover family are used for lifting vacuum-sealed, flat loads, such as glass panes, sheet metal and plastic or wooden boards. The lifting devices of the eT-Hover-panel series start at a load capacity of 250 kg. Depending on the base frame and equipment, such as longitudinal cross beam and suction plate selection, a maximum load capacity of up to 4,000 kg can be achieved. As an extension of this series, a very flat version was designed for removal from narrow high-bay drawer racks. Things are made easier by a telescopic and swivelling handle with operating panel, which is also used in other models. The operating panel can be used to control all relevant processes if the user desires. A vacuum pump with an integrated non-return valve generates the vacuum. Devices of this design are currently available with a load capacity of 500 or 750 kg.
The eT-Hover-modesty series lifting devices serve as an alternative to similar, more extensively equipped devices. Devices of this series are equipped with two handles for easy manoeuvring and positioning. Despite its simple design, it fulfills all required functions. The devices can be rotated pneumatically, but can optionally also be rotated manually. The new feature of this series is a version that pneumatically enables to swivel of the workpieces by 90°. Lifting devices of this series are operated entirely with compressed air; therefore an electrical connection is not necessary. Due to their compact design and vacuum generation by an ejector, these lifting devices have a very low dead weight.
The Nemo type electronic suction device, modified by Eurotech, is a mobile, electronic, handheld suction device. With a holding force of up to 170 kg, the Nemo can be used on just about any surface. This handheld suction device makes it possible to easily move various materials and place them down safely. The vacuum pump installed in the handle generates the necessary vacuum to hold the workpiece steadily. The installed vacuum meter with red/green area is used for monitoring. The vacuum pump is equipped with an economy circuit. Once the pump reaches the safe negative pressure, it will be switched off. If the vacuum in the suction device drops, it will automatically switch on again. The Nemo battery-powered, handheld, suction device is the perfect addition to the tool kit for a wide variety of professionals – from construction professionals and warehouse employees to service and workshop employees. In all sectors, where heavy lifting is the order of the day, this powerful tool minimises the risk of damaging expensive materials. Nemo maximises productivity while reducing the physical workload.

Power Supply Product
Bi-directional DC-DC converter series has extended voltage
TDK Corporation (TSE 6762) announces the introduction of the EZA2500W-32048 TDK-Lambda brand bi-directional DC-DC converter model to its EZA series. The extended high voltage range now covers 260 to 400Vdc and the lower voltage 36 to 65Vdc. The operating temperature has been increased to -10 to +50°C. Double sided protective board coating and long-life dust resistant fans have also been included.
Designed for energy storage systems with rechargeable batteries, this 2500W digitally controlled, compact 1U power supply can seamlessly change conversion direction from high voltage dc sources, powered by solar or wind, to 48Vdc batteries and vice versa. Other applications include lithium-ion battery testing as well as the use of regenerated energy from robots, cranes, autonomous ground vehicles and lifts. The EZA2500 can be used to replace large power resistors currently used for lift braking and use that previously dissipated energy to charge batteries. That stored energy can be used to either provide peak power for high torque demands or as battery back-up for power cuts.
The output voltage and current can be programmed and monitored using the RS-485 communications port. Multiple units can be operated in parallel by using the RS-485 interface to set units for “droop mode” current share. Alarm signals are also accessible, as well as remote on/off and under/over voltage functionality. The high voltage (grid) to low voltage (battery) isolation is 3,000Vac, grid to ground 2,000Vac and battery to ground 500Vac.
The dimensions for the EZA2500 are 43.6mm (1U) high, 423mm wide and 400mm deep. All models in the EZA series are certified to the IEC/EN/UL 60950-1 and IEC/EN/UL 62368-1 safety standards with CE marking for the Low Voltage, EMC and RoHS Directives. A five-year warranty is standard.

Industry 4.0 progress
In an ordinary year, PI (Profibus & Profinet International) would already – and once again – have presented its progress on Industry 4.0 work at the Hanover Fair – but this is no ordinary year. Nevertheless, the working group experts are working tirelessly on implementing concepts like the use of Profinet over TSN, fail-safe machine-to-machine communication and information models for vertical communication – virtually and at a safe distance, of course.
Obviously, this is not an easy time for an organization which has committed itself to the networking of automation systems, and especially also those of technical experts. PI has been part of the digital transformation from the very beginning, though, which makes it ideally equipped for this situation. This being the case, it is no wonder that the working groups chose to continue developing their concepts. Online meetings and processes have been part of everyday work at PI for many years, enabling effective and easy cooperation. To share this progress with Profinet users as well, PI is now implementing a number of different virtual methods of communication.
The focal point of this communication is the PI website, www.profibus.com/I40, where “Industry 4.0” is being rolled out again in its entirety. PI is focusing on the highlights of its Industry 4.0 work here, beginning with Profinet over TSN, OPC UA Safety and vertical communication. Additional concepts will be addressed and added successively over time. PI won’t just be providing an overview of the technology and leaving it at that – technical details on solutions and use cases for applications will be added as well. This gives device manufacturers and users solid information for their own implementation of Industry 4.0-compliant integration.
In addition to this digital content, PI will also be visualizing the Industry 4.0 workshop to enable discussion with users and enter into dialog in these trying times – times which everyone at PI hopes will be over soon. Regardless, the working groups will continue to work hard on implementing Industry 4.0, in keeping with the motto: Go digital. Go Profinet .
