December, 2014 Continued from page 59 A producer of conveyor systems
for the food and beverage sector needed to design an IP67-compliant product that could withstand harsh conditions such as immersion in wash-down situations. Adopting a connector-based assembly with Han- Yellock modular connectors in place of hardwiring allowed the company to reduce install time and mainte- nance downtime and increase the throughput of the conveyor by 15 percent, with cost savings applied directly to the bottom line.
Acoustic Microscopes Benefit A maker of acoustic microscopes
for analyzing the integrity of semi- conductors was planning a new model that would require 120 leads that carried varying voltages. The goal was to assemble a machine with

components as analog-to-digital con- verters (ADCs), digital-to-analog con- verters (DACs), field-programmable gate arrays (FPGAs), and digital sig- nal processors (DSPs) to form, trans- mit, and receive different forms of modulated and pulsed waveforms. In general, the test equipment devel- oped for military electronic use must be rugged enough to withstand field use and broadband enough to handle the wide frequency ranges used in military electronic systems. As part of those military systems, many indi- vidual components, such as anten- nas, amplifiers, filters, and switches, can require maintenance and upkeep as part of achieving top-level system performance, and essential test equipment such as signal generators and spectrum analyzers can help with that component-level mainte- nance as well. With the growing complexity of
military electronics systems, the com- plexity of test equipment has fol- lowed, with such instruments as vec- tor signal generators and vector sig- nal analyzers developed to represent the increasingly complex modulated signals used in military electronic sys- tems, helping to recreate test signals with complex relationships of ampli- tude and phase. In most cases, portable as well as
laboratory versions of test equipment are available for in-field use, equipped with the capabilities and necessary interfaces to perform electrical tests according to a number of different military environmental test stan- dards,
AS9100:2009 including MIL-STD-810E,
MIL-STD-202, and MIL-STD-883. A number of suppliers provide useful guidance with radar testing. “Simu - lation and Verification of Pulse Doppler Radar Systems,” is a presen- tation available from Agilent Technologies (
www.agilent.com), for example, that provides examples of the pulse generators, signal proces- sors, and signal analyzers that can be used for testing pulsed Doppler radar systems. And Tektronix offers a 20- page application note with practical information on using an arbitrary waveform generator to produce radar pulses: “Generating Advanced Radar Signals Using Arbitrary Waveform Generators.” r

a small footprint, but the design engineers ran out of interior space for such an elaborate power distribu- tion setup. However, by switching to two
heavy-duty connectors with 60 pins each, they were able to streamline the interior wiring and achieve the desired footprint while also benefit- ing from cost savings; internal wiring bundles were eliminated and less metal paneling was required in the acoustic microscope system. In fact, any company using hardwiring in manufacturing or upgrading equip- ment is a candidate to save assembly time and money, and improve effi- ciency and customer satisfaction, by
adding connectors at appropriate locations on wiring and cable runs.
Modularity Means Flexibility The Harting Han-Modular®
connector system introduced the con- cept of user-defined modularity, allowing each customer to build cus- tom connectors with standard cata- log components. With more than 40 inserts, the Han-Modular connector system supports specific power, sig- nal, or data loads as well as fiber- optic, D-sub, coaxial, and pneumatic applications and can withstand harsh environments, including dirt, dust, humidity, tension, vibration, and wide temperature swings. These
modular connectors can handle cur- rents to 200A and voltages to 5000V. Models are available where high EMC protection is required, as well as for high mating cycles in prototyp- ing and testing scenarios and stain- less-steel units for hygienic applica- tions such as food or pharmaceutical production. In addition, these modu- lar connectors can generally replace standard connectors without modifi- cations to a machine or system. Contact: Harting, Inc. of North
