Line-scan cameras provide 2k resolution Teledyne Dalsa (Waterloo, Ontario) has released two additional members within its Piranha-4 family of line-scan cameras, bringing the model count to more than 10. The new cameras have 2k resolution and combine CMOS image sensor improvements with improved signal-to-noise ratio for monochrome and color imaging. The monochrome Piranha-4 dual-line scan camera delivers a maximum line rate of 100kHz in TDI mode, or 200kHz in rea mode. The Piranha-4 2k trilinear model delivers a maximum line rate of 70kHz. Advanced features include sub-pixel spatial correction, lens and shading correction, and flat field correction. Both the color and monochrome models provide a GenICam-compliant interface with cable lengths of up to 30 meters. Color applications include print inspection, banknote inspection, package and label inspection, and food inspection. Monochrome applications include railway inspection, printing, wood, film, and label inspection, and general machine vision applications. Teledyne Dalsa www.teledynedalsa.com High temperature DC-DC converters for down-hole tools reduce design time International Rectifier, has introduced the HTH27022S and HTM27092S isolated hybrid hermetic DC-DC converters for high temperature and high shock environments such as oil drilling applications and mud turbine generators. Featuring an operating case temperature of 165ºC with transient up to 175ºC and with a high nominal input voltage of 270 V, the HTH27022S and HTM27092S are commercial off-the-shelf (COTS) converters that can reduce design cycle time, size and design costs associated with high temperature applications. The HTH27022S and HTM27092S products feature internal EMI filter, magnetically coupled current feedback, undervoltage lockout, output over-voltage limiter, external inhibit and short circuit and overload protection. Additional features include small size, low weight and high tolerance to environmental stresses such as wide temperature extremes and severe shock and vibration. Electrical and environmental qualification reports are available for order through local sales representatives.

This MINI-SMD crystal offers a frequency tolerance of ±10 ppm and a temperature stability from ±8 ppm. The user can choose from aging rates of ±1 ppm to ±3 ppm/year, which means that the frequency tolerances, as well as narrowband and broadband wireless applications, can be realised. The crystals, which can be easily configured with a Pierce oscillator (with two external capacities to GND), can also replace high-frequency third overtone crystals and highfrequency crystal oscillators (as long as this is possible with the IC being used). In addition to wireless applications, this crystal can also be used in telecom, medical and industrial applications. Thanks to its very high fundamental range, it also opens up simple opportunities for circuit designers. Petermann-Technik www.petermann-technik.com 100-Ohm backplane connector will support 25 Gbps data rates A range of modular backplane connector features low mating force and a 1.90 x 1.35 mm pitch for optimal performance in traditional backplane and midplane architectures. Molex’ Impact 100-Ohm backplane connector offers speed and density in a modular package designed for high speed applications, with data rates up to 25 Gbps and signal density up to 80 differential pairs per linear inch when using a 6-pair configuration. The Impact backplane connector is suitable for high speed networking equipment and storage servers in the data and telecommunications, medical, military and aerospace industries and conforms to IEEE 10GBASE-KR and OIF Stat Eye Compliant end-toend channel performance. With a 1.90 x 1.35 mm grid, which reduces PCB routing complexity and cost, the broad-edge coupled, differential-pair Impact backplane system supports high bandwidth needs while minimising board and system real estate usage. Compliant pin attach options (0.39 and 0.46 mm) provide the flexibility to optimise designs for superior mechanical and electrical performance in traditional backplane or midplane architectures. The Impact daughtercard mating interface uses an in-line staggered, bifurcated contact system that reduces the mating force per pin and provides ground-signal sequencing without the need for multiple backplane signal-pin heights. Available in conventional, coplanar, mezzanine, orthogonal and orthogonal direct configurations, signal module options vary by configuration and are offered in two to six 6 pairs. Power modules are available in three to six pair sizes in conventional, coplanar and mezzanine configurations with current ratings from 60.0 to 120.0 A per module.
