Terminal blocks

The QUiX-COMBICON insulation displacement, printed circuit board terminal blocks are busable and pluggable. Made as a time-saver for "daisy chain" wiring applications, they are available with 5-mm pin spacing, 10A at 300V, and in 2 through 6 positions. Plug is suitable for multiple printed circuit board wiring. Phoenix Contact, www.phoenixcon.com. Enter 668

DPSS lasers

PowerGator(TM) 355-10 industrial-grade DPSS lasers deliver 10W average power and greater than 100 GW/cm2 peak power intensity. The system microfabricates high aspect ratio features in hard materials more than 1 mm thick. Short 15 ns pulses and 355 nm (UV) improve plasma penetration. Other features reduce heat-induced effects, microcracking, and redeposition of material, yielding higher quality surfaces. High beam quality permits high focusability for feature sizes below 10 microns, critical for a number of micromachining applications. Lambda Physik, www.lambdaphysik.com. Enter 669

Biochip

Molecular test biochips measure approximately 1/4 cm2. Each biochip contains 128 homogeneous "wells" that are 100 microns in diameter. Biological mini-probes can be linked to these wells, effectively allowing 128 miniaturized different tests on a chip. The electronic circuits fabricated on the same chip are used to replace optical analysis of samples with measurements of electric currents depending on the test samples' properties. The result is a reportedly smaller-than-average optical system. Infineon Technologies Corp., www.infineon.com. Enter 670

Switching controller

The FAN4822 PFC controller is an average-current boost-type device that functions with power supplies of 500W or more and employs zero-voltage switching (ZVS) control circuitry. This circuitry is designed for efficient operation at high switching frequencies. The continuous boost architecture allows designs to achieve a power factor up to 98%.
