New Vishay Sfernice PRV4 Panel Potentiometer ....

Features High 2-W Power Rating and Cermet Element in Compact, Fully Sealed Package

Device Offers Resistance Ranges from 20W to 10 MW and 1% Typical Contact Resistance Variation for Industrial Control Applications

MALVERN, PENNSYLVANIA - May 18, 2007 - Vishay Intertechnology Inc. (NYSE: VSH) today announced a new compact panel potentiometer with a cermet element and a high 2-W power rating.

With US bushing threads and a fully sealed package, the PRV4 is intended for industrial control panel, heavy-duty control, and position control applications in end products including trucks and tractors, HVAC systems, welding machines, tooling machines, field and mine equipment, and water-resistant equipment.

With only a 19.6-mm diameter, the new device is smaller than other 2-W panel potentiometers, offering designers a compact alternative to the Mil RV4. Its cermet element provides better stability than carbon elements, while its nickel-plated brass shaft offers greater reliability and robustness. Custom shafts are available in accordance to drawings supplied by customers.

The new Vishay Sfernice device offers resistance ranges from 20W to 10MW, with a low 1% typical contact resistance variation. The potentiometer features a maximum operating torque of 4.3 oz.-inch, and an end stop torque of 6 lb.-inch. An operating temperature range of -55°C to +125°C ensures reliable operation even in extreme environments.

The PRV4 uses faston 2.86 connections and its electrical performance is in accordance with MIL-PRF-94 standards.

Samples and production quantities of the PRV4 are available now, with lead times of eight weeks for larger orders. Pricing is $6.00 per unit in small quantities, and $4.00 per unit in large quantities.
