MEDER electronic Announces 3-D Magnetic Mapping Of Reed Sensors
Optimize components and eliminate issues that may result in faulty operations
Meder electronic Inc., a manufacturer of precise, reliable, and long-lasting miniature switches, sensors and relays, announces its 3-dimensional magnetic mapping capabilities for reed sensors. This process allows designers to more accurately place sensors and magnetic components within a system, thus eliminating any issues that may result in faulty operation.
MEDER electronic conducts 3-D magnetic mapping by incrementally measuring the reed sensor’s closure and opening points as it enters and exits the influence of a magnetic field. This information is then analyzed, allowing the user to visualize the magnetic field in three dimensions. Understanding the interacting magnetic fields allows designers to better position the magnet and sensor in the system for optimal operation. 3-D mapping also helps designers adjust the magnetic sensitivity of the reed sensor and/or the magnet’s size and strength.
The ability to know where the key operating points are is critical to sensor applications, because it allows designers to properly position the magnet and sensor well within appropriate guard bands and avoid tolerance issues. It is particularly useful in applications using more than one reed sensor or more than one magnet. For applications in which ferromagnetic material like iron, steel, nickel or cobalt are present in the area where sensing takes place, 3-D modeling becomes quite extensive and unpredictable, so magnetic mapping is the only way to know for sure where the boundaries are.
In addition to ensuring operations are well within the magnetic envelopes to avoid tolerance issues, 3D magnetic mapping helps designers optimize the sensor and magnet components, which can significantly reduce costs.
MotorSolve v4 with New Switched-Reluctance Analysis & Enhancements to Thermal Module
Infolytica Corp. has announced MotorSolve v4 is available. This release has numerous improvements, which include a new SRM analysis module and major enhancements to the recently added Thermal analysis module.
MotorSolve now includes a fully automated finite element analysis (FEA) module for switched-reluctance machines. Users can select between an extremely rapid static FEA solve (well suited for early in the design process) or a full time-stepping non-linear FEA simulation (well suited for final design verification), depending on the level of accuracy they require.
MotorSolve SRM outputs the standard performance charts and field plots that motor designers require. Design parameters, performance data and summary comparisons can be recorded in an experimental log or report. Results are also easily accessible either with the use of the clipboard or export functionality.
"We refer to MotorSolve as an automated FEA design tool since the user doesn't have to worry about the mesh or any typical post-processing tasks associated with FEA software," said Chad Ghalamzan, Marketing manager at Infolytica Corp. "They select from an extensive list of performance indicators, quantities, charts, field plots, etc, what data they require. MotorSolve runs the automated FEA solver by handling all these 'typical' pre and post processing steps for the user, and produces the desired results as required."
Building on the recently added MotorSolve Thermal module, new cooling types and other enhancements have been added to the package. Another key feature is the ability to display temperature fields as a shaded plot. This can be shown on radial or axial slices – extremely useful when trying to determine hot spots and heat flow between components.
The MotorSolve software suite supports brushless dc (BLDC), induction machine (IM) and switched reluctance machine (SRM) devices. Infolytica plans to release a new DC motor module by the end of 2012 as well.
CST Launches New Product CST Boardcheck
Computer Simulation Technology (CST) has launched a new product that analyzes PCBs with respect to EMC and SI related design rules.
Design engineers dealing with electromagnetic compatibility (EMC) and signal integrity (SI) of PCBs, can now employ CST Boardcheck to get a quick overview of potential problems in their layout. CST Boardcheck supports a multitude of popular layout formats such as Cadence Allegro, Zuken CR 5000, Mentor Graphics Expedition and ODB++, which are read-in using the sophisticated CST Studio Suite import filters.
Once imported, the engineer can easily check nets critical to the design against a number of individually selectable, industrially well established design rules, in order to ensure the EMC and SI of the design. EMC rules include net reference (net crossing split), wiring, crosstalk (critical net near I/O net), decoupling (capacitor density), and placement (I/O filter distance). SI rules include net integrity (net length) and via integrity (unconnected via pads). CST Boardcheck rapidly generates a report listing all violations and enables the user to highlight the corresponding problematic portions of the design.
If required, the user can carry out further analyses with a CST PCB Studio solver or perform a push-button export for 3D full wave simulation in CST Microwave Studio.
“We are happy to see that with the release of CST Boardcheck, the knowledge and expertise of EMSAT is now available inside CST Studio Suite. EMSAT is a well established design rule checker for EMC and SI rules used by major companies world-wide that is built based on hundreds of man-years expertise gathered at IBM”, commented Dr. Bruce Archambeault, Distinguished Engineer, IBM. “This brings the analysis speed of design rule checking to a 3D environment and enables users to quickly and easily study the detected violations in full detail.”
“Our customers require tools that enable them to find problems in their designs quickly,“ said Dr. Bernhard Wagner, Managing Director Sales & Marketing, CST. “An excellent design rule checker such as EMSAT can help them to survey their device. With the release of CST Boardcheck we have made the state-of-the-art EMSAT rules for EMC and SI available to them, stand alone or inside CST Studio Suite.”
AVX’s Multilayer Organic High Current Inductors Now in 0402 Size
AVX Corp. has developed a multilayer organic RF inductor in a 0402 case size that offers high current in a small footprint. Providing high current and high self-resonance, the RoHS-compliant device features an inductance range of 1 nH to 32 nH.

Omron to Release High Capacity DC Power Relay
Omron Corp. has announced the release of the G9EN DC power relay. The relay is 50 percent smaller and lighter than Omron's previous comparable relays because of the use of newly developed proprietary sealing technologies and new magnetic control methods.
With the global expansion of the market for environmentally-friendly clean energy vehicles such as hybrid and fuel-cell cars, there is quickly growing demand for mileage extension and new high-capacity battery DC load control technologies. Omron has been working over the last decade to meet the needs of clean energy car manufacturers for greater circuit design flexibility and components that enable down-sizing and weight reduction of onboard electrical equipment. With the G9EN (60A), Omron is taking down-sizing and weight reduction to the next level, and the company is also preparing for the release of other advanced new products including a 150A main relay, and an air-break switch pre-charge relay.
Features of the G9EN DC power relay include a 50 percent reduction in volume (28 by 40 by 50 mm) and weight (140g) compared with previous Omron models in the same product class, and non-polarized contact circuit (contact terminal) (the first model in this class to feature this). This contributes not only to device downsizing and weight-reduction, but also makes wiring and mounting much simpler.
Main applications include Main relays and pre-charge relays for vehicles with high voltage batteries such as hybrid and electric vehicles (in BDUs – Battery Disconnect Units); chargers, feeders, and accessories for electric vehicles and plug-in hybrid cars; feeder circuits and condensers for fuel cell cogeneration systems and solar power systems; and Industrial equipment (elevators, industrial robots, testing devices, etc).
DC power relays enclose pressurized gas which enables them to hinder arc formation by cooling. Typically, a ceramic housing is used to keep the pressurized gas sealed in, but Omron has achieved down-sizing and weight reduction of the relay body by changing the ceramic sealing construction from a conventional box-shaped ceramic case to a combination of ceramic plating and metal casing.
This makes it possible to maintain or increase the interior volume of the air-tight space of the main contact circuit (main terminal) structure compared with existing comparable products.
Omron has designed the layout, spacing, and shape of the switching circuit and the permanent magnet circuit specifically to extinguish the arcing which occurs during DC load interruption across narrow contact gaps.
This enables high-speed arc interruption regardless of current direction, and has resulted in a non-polarized main contact circuit (main terminal) which up till now has been difficult to achieve with direct-current type relays using arc interruption via magnetic blow-out.
This non-polarization means the device is suitable for use in applications requiring two-way current flow. It also means it is not necessary to consider the mounting direction or the orientation of the device, making wiring and mounting much easier, and reducing the risk of incorrect wiring.
