Programmable R-to-D Converters

The RD-19230 series of 16-bit resolver-to-digital converters is ideal for high-performance industrial and commercial positioning systems. The single CMOS monolithic chip offers user-programmable encoder simulation, resolution, bandwidth, tracking rate and velocity scaling. Accuracy is 2.3 arc minutes, and a synthesized reference capability ensures accuracy with a phase shift of up to 45 degrees. ILC Data Device Corp, 105 Wilbur Pl, Bohemia, NY 11716-2482. 516-567-5600.

Sealed Miniature Switches

V9 series components are miniature single-pole switches sealed and pressure-tested against the ingress of liquids. Versions now include a 3mm contact gap snap-action switch for European requirements, and a positive-action, forced-break switch for safety applications. The moving contact is silver and the fixed contacts are silver cadmium oxide. SAIA-Burgess Electronics Inc, 1335 Barclay Blvd, Buffalo Grove, IL 60089-4527. 800-644-7032. USA.com Circle 453.

High-Power Laser Diodes

A wide selection of laser emitters in the 650nm to 1550nm range are being offered at various power outputs. Configurations include PIN photo diodes and laser modules, the latter featuring integrated driver circuitry and built-in GaAs monitor photo diodes. Applications for the product line include laser pointers, barcode scanners and readers, telecom systems, and medical devices such as diagnostic and surgical systems.

Power Capacitors

These power capacitors employ a range of dielectric materials, electrode material, impregnation and packaging technologies, with capacitance up to 12,000µF and maximum voltage of 36 kV. The TFM/IFM Series is for DC filtering; the PPX/FPX Series is designed for GTO protection; the FAI Series is for use in tuning induction heating equipment; and there are capacitors for defibrillators and energy storage applications.

Current Sensing Relays

Current reaching a set level on the trip-point adjustment of the CR4395 series energizes the electromechanical relay. A precision voltage reference circuit ensures a highly repeatable trip-point. Variable time delays inhibit activation during motor start-up, and electronic isolation between circuits protects instrumentation from high voltage. The series is offered in trip ranges from 0.010 to 100 AC amps. CR Magnetics Inc, 544 Axminister Dr, Fenton, MO 63026. 314-343-8518. http://www.crmagnetics.com Circle 454.
