High-Speed Valve Driver Offers 160 Microsecond Valve Open Time to Precisely Synchronize Gas Flow with Pulsing Lasers


The laboratory-ready Iota One precision valve driver system from Parker Hannifin’s Pneutronics Division is ideal for research laboratories and critical laser spectroscopy application. The Iota One is a self-contained, rack-mountable system that supplies extremely repeatable control and synchronization of gas flow and laser firing. Its driver offers pulse duration ranges in microseconds, milliseconds, or longer, with internally-generated pulse trains achieved by setting on and off times or an operating frequency. Two externally triggered modes can be selected allowing partial or complete external control.

In addition, the Iota One includes front panel BNC jacks for both input and output TTL signals. The single channel unit produces repetition rates up to 250 Hertz (maximum 50-percent duty cycle), while the multi-channel unit produces repetition rates up to 999 Hertz.

The Pneutronics Division of Parker Hannifin provides precision control of inert and aggressive gas and liquid media through its full range of high performance miniature fluidic products and systems. With application-specific solutions ranging from miniature digital and proportional solenoid valves and pumps to electronic pressure control modules, Pneutronics meets the stringent operating requirements of OEM instrument builders worldwide..

With annual sales exceeding $9 billion, Parker Hannifin is the world's leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety of commercial, mobile, industrial and aerospace markets. The company employs more than 57,000 people in 46 countries around the world. Parker has increased its annual dividends paid to shareholders for 50 consecutive years, among the top five longest-running dividend-increase records in the S&P 500 index.
