Advertorials New Low Profile, Quick Release Interconnect from
Amphenol Offers High Performance RADLOK provides low insertion and extraction forces with high mating cycle rating
Amphenol Industrial Global Operations, a global leader in interconnect systems, has introduced a low profile, quick release, high power interconnect which utilises the company’s latest R4 RADSOK technology. The new RADLOK product line provides low insertion and extraction forces with a high mating cycle rating for high power interconnects, making it perfect for frequent mating applications.
This high performance Amphenol connection system features a versatile, low profile right angle design making it ideal for use in the automotive, heavy equipment, power/battery storage, hybrid- electric system, power interconnect and factory automation markets. Its integrated positive mechanical lock/release feature enhances cycle durability.
Amphenol’s cost-effective RADLOK product line can be used as a battery interconnect both internally (cell-to-cell) and externally (battery-to-battery or array-to-power storage units); in electric vehicles, hybrid electric vehicles and fuel cell electric vehicles as well as in servers connecting power to the board.
The connection system employs Amphenol’s unique R4 RADSOK technology that lowers voltage drop, maximises contact surface and reduces temperature rise. It features a rugged, low-profile over mold design making it impact resistant. RADLOK is a preassembled one-piece over mold connector that helps to reduce end user assembly costs. It’s color-coded for visual identification, and easily installed with a simple push and click.
These RoHS compliant connectors have a maximum current rating of 400A, a maximum DC voltage rating of 1,000 V and an operating temperature range of -40ºC to +125ºC. They are available in either crimp-on versions or integrated directly onto cable with customisable lug end configuration.

Wireless Torque Sensor Cuts out Slip Rings
Machine designers are expected to make a beeline to Sensor Technology’s stand at the Sensors & Instrumentation Exhibition, NEC, Birmingham to see a wireless technology for measuring power in drive shafts and other rotating machine elements.
The company’s TorqSense Rotary Torque Sensors are unlike traditional slip ring transducers, using a simple non-contact radio link for collecting real-time torque signals. This means that machine builders and control engineers can do away with expensive and temperamental slip rings – instead, simply mounting the sensors and checking the radio connection.
In a SAW sensor, the surface waves are produced by passing an alternating voltage across the terminals of two interleaved comb-shaped arrays, laid onto one end of a piezoelectric substrate. A receiving array at the other end of the transducer converts the wave into an electric signal.
The frequency of the oscillation used is typically 200MHz. The frequency-basis of the TorqSense concept gives a wide bandwidth and the susceptibility to electronic interference, common with other analogue-based techniques such as inductive devices, is eliminated.

testers Telonic Instruments have introduced a new range of Hipot (Flash) and Insulation Resistance testers manufactured by Japan based Kikusui. Designated the TOS5300 the three models in the range are designed for use in Withstanding Voltage and Insulation Resistance testing to help ensure the safety of Electrical/Electronic components / equipment. Incorporating an innovative PWM amplifier that achieves high stability and has an input voltage regulation of.3%. The series offer rise and fall time control of the test voltage and a stable output which is unaffected by mains voltage variations, plus the ability to select 50 or 60Hz test frequency. Upper and lower
current limits can be set within the range of 0.01mA to 110mA in AC mode and 0.01mA to 11mA in DC mode. AC test voltage is settable from 0.05kV to 5kV. D.C test voltages can be varied from 0 to 6kV. All models will operate from any global AC input voltages and frequencies; and are equipped with a USB interface.

enables high-reliability lighting. ON Semiconductor’s NUD4700 device in the POWERMITE (DO- 216) package offers a compact shunt-protection solution for high-brightness LEDs (HBLEDs) and medium-power LEDs (MPLEDs), in applications where continuous light output is a critical need. These applications include high-reliability lighting in transportation systems such as aircraft, rail and automobiles. LEDs sometimes fail into a SHORT, but often fail in the OPEN (non- conducting) state. In the latter case, if a shunt mechanism is absent, the entire LED string is rendered dark, thereby significantly decreasing light output and lamp lifetime. Street lighting is another application where continuous light output is critical despite the failing of a few LEDs, because it is labour-intensive and hence expensive to replace a broken street lamp. When each LED is equipped with a shunt protector in parallel, the failing of one of the LEDs causes the corresponding shunt to conduct the designed level of DC current, thereby keeping the remaining LEDs in the string lit.
LED Shunt Protector from ON Semiconductor New range of Hipot and Insulation Resistance
In general HBLEDs operate at a minimum current of 350mA. In certain cases a single HBLED emitter can sustain as much as 1A DC. Utilizing a unique technology with snap-back capability, the NUD4700 exhibits low leakage during normal LED operation, a breakdown voltage of ~6.5V and a high DC current capability exceeding 1A. In order to keep heat dissipation to a minimum, its forward voltage is maintained below 1.2V, in contrast to the 3-4V forward voltage of the LED.
