EMKA have developed an extensive range
of hinge types under the 1030 series umbrella

Use of a traditional lay-on protruding door has a number of advantages in electrical or electronic control enclosures since it ensures the greatest usable door area almost to the width of the frame and can often open to 180º even when cabinets are mounted side by side. EMKA have therefore developed an extensive range of hinge types under the 1030 series umbrella, so as to ensure that builders of custom and standard panels can easily find a suitable item for flange returns within the 16mm to 25mm range, or greater.

EMKA 1030 series hinges feature types which fit externally and versions which are concealed internally. Installation methods include screws, welding or stud fixing. All the 1030 series may be demounted with the door open to improve access to the interior or to door mounted equipment during maintenance or build/installation. This has been achieved by use of a lift-off design or removable pins.

Picture shows the EMKA 1030 series hinges featuring types which fit externally and versions which are concealed internally. Installation methods include screws, welding or stud fixing.

This type of cabinet comes in many different types and sizes and are used in environments from offices/factories to oil rigs - so EMKA 1030 hinges are supplied in a range of appropriate materials and finishes. These include: mild steel in ready for weld and paint, or zinc plated; zinc die cast finished in chrome or black powder coat; or stainless steel, for the best in strength and corrosion resistance.

Up to 2m plus height door units are catered for using multiples of 2, 3 or 4 hinges per door, in order to accommodate the weight of the door itself and its indicators, controls etc.

Circular Hybrid Technology from Molex
integrates power and data lines in one connector

Molex Incorporated (NASDAQ: MOLX and MOLXA) has introduced an innovative Circular Hybrid Technology (CHT) connector that combines Cat 5e data speed and power supply for high signal integrity and excellent performance. By combining both the power and data lines in one M12 connector, the CHT reduces both installation and cabling costs in process and automation control applications as well as in HVAC control systems, telecoms infrastructure and base stations.

Based on the robust circular M12 push/pull design, the CHT connector comprises four Cat 5e data lines and two power lines carrying 10A. It is overmoulded to ensure complete sealing and provide strain relief. The fully-shielded 4-pin array with wrap around metal tube (patent pending) allows for perfect signal integrity and performance - the two overlapping tubes channel the signal through without affecting crosstalk and EMI.

Circular Hybrid Technology from Molex integrates power and data lines in one connector.

The CHT 4+2 configuration is already in production in the M12 form factor. "As the Molex shielding concept of the Circular Hybrid Technology connector is not limited to the M12 format," says Gerd Klaiber, European Product Manager for Automation and Electrical Products, "Molex is able to adapt the technology to meet specific customer needs and requirements." Plans to further extend the Molex CHT connector line-up, to include M16 and M23 formats, are in development.

Versatile Y-Junction Chip is suitable for
investigations into fluid interface with laminar flow

Dolomite, a world leader in microfluidic design and manufacture, has introduced the glass microfluidic Y-Junction Chip. Enabling liquid-liquid contact of immiscible fluid streams, as well as investigations into the diffusion of molecules between parallel laminar flow streams, the chip has extremely smooth channel surfaces for an uninterrupted flow.

Picture shows the Y-Junction chip which is available with hydrophilic, hydrophobic, platinum, or gold coatings.

With a compact size of 22.5 x 15 mm, the Y-Junction Chip is compatible with the Mitos Chip Holder H and the Mitos Edge Connector, facilitating ease of use. A wide temperature and pressure range in combination with excellent chemical compatibility enable a broad range of fluids to be used.  Furthermore, excellent spectral transmission facilitates high visibility, making access with microscopy systems quick and easy.

A range of customised options enable the chip to be tailored to fulfil individual user specifications. As such, it can be etched to a range of different depths, and custom channel layouts can be specified. As the surface of the channel walls has an effect on the fluid, the Y-Junction chip is available with hydrophilic, hydrophobic, platinum, or gold coatings.

Stanyl PA46 makes new brushless DC
motor possible for Dunkermotoren GmbH

Dunkermotoren GmbH a world class leader in high quality motion control solutions, has successfully used an adapted grade of Stanyl® PA46 for its BG-series of brushless E-motors.

As a global player in the field of high quality motion control solutions and thanks to its initial success and subsequent market demand, Dunkermotoren GmbH wanted to extend its well-established portfolio of BG-series of high end brushless motors by adding two more compact, high efficiency and high output motors.

Working with molder PVS-Kunststofftechnik GmbH + Co and DSM Engineering Plastics, Stanyl TE250F6 was approved for this application. This included UL1446 testing for the higher temperature class. The excellent high temperature ageing properties of Stanyl PA46 TE250F6 for thin-walled overmolded insulating systems solved breaking issues during winding experienced with competitive materials, especially at thicker diameter copper wire.

According to Pascal Feijts, Application Development Manager Gears, Pumps & E-motors at DSM Engineering Plastics, Stanyl PA46 TE250F6 offers the possibility to low wall thicknesses (down to 0.35mm) in high heat (180ºC) over molded insulating systems according UL1446 thus enabling high speed winding. "Thanks to its excellent flow, high heat ageing and mechanical properties, Stanyl was able to deliver excellent high heat mechanical properties, good heat ageing performance and excellent flow & strenght for the overmolded stator used in these motors." Mr. Feijts added: "In order to meet the needs of this relatively new application area, we upgraded our standard Stanyl grade to a lower thickness in the UL1446 high temperature insulation class."

Stanyl TE250F6 has already been applied successfully in overmolded stators for several years. The material offers a unique solution for reducing wall thickness - one of the key ways to reduce system costs - without loss of quality, in fact offering increased quality. Previously, Stanyl TE250F6 could only be used for these types of applications in combination with UL1446 for temperature class 180(H) with wall thicknessof 0,69mm but not for wall thickness 0,35mm. Now, with the UL1446 180(H) designation the grade can also be used for insulating systems down to wall thicknesses of 0,35mm.

Pascal Feijts: "This Technology is relatively new and a logical step after using varnish (dip & bake) based insulation materials in combination with high performance plastics end-laminates. Beside Technology advantages it will also bring ecological and logistics advantages. The recognition according to UL1446 thermal class 180(H) of Stanyl PA46 TE250F6 in the low wall thickness of 0,35mm gives new opportunities for electric motors, transformers or coils."

Andreas Winterhalder, Head of Motor Development at Dunkermotoren GmbH says: "We are constantly looking to meet the increasing demands for cost effective and reliable drive solutions in industrial automation, medical devices & laboratory equipment, door automation, sun protection as well as land, marine and aerospace vehicles. However, insufficient and inconsistent performance of currently used material did not meet higher requirements for our new and upgraded brushless motor range. Stanyl TE250F6 proved the best material for the application thanks to its excellent flow and mechanical properties at high temperatures."
