BI Technologies Develops Precision Potentiometers for Heavy Sideload Applications

FULLERTON, CA (January 23, 2007) - Providing design engineers with an ideal mechanical set-up for applications involving feedback positioning, TT electronics BI Technologies Electronic Components Division has enhanced four of its precision potentiometers. Designated the model 7288, 7388, 7488 and 8148 devices, the potentiometers are capable of up to one pound (16oz.) of sideload, and feature industry standard specifications that have been designed-in worldwide.

According to Barbara Wiesinger, director of product development for BI Technologies Electronic Components Division, the front bushing of the potentiometers has been upgraded with superior bearing materials and the rear bearing was redesigned to provide for additional internal stability. "Not only do these potentiometers meet or exceed the rotational life of the standard products, but they do so while under the heavy side load," said Wiesinger. "The improved potentiometers are ideal for position feedback and closed loop systems where a mounting configuration that offers full support to the front bushing of the potentiometer is not available."

According to Wiesinger, the enhanced potentiometers are modeled after BI Technologies' proven industry standard potentiometers: the model 7288 device is based on BI's 7286 10-turn wirewound potentiometer; the model 7388 is based on BI's 7386 3-turn wirewound potentiometer; the model 7488 is based on BI's 7486 5-turn wirewound potentiometer; and the 8148 device is modeled after BI's 8146 10-turn hybrid potentiometer. All of the precision devices feature industry standard specifications, including 7/8" diameter, 1/4" shaft and 3/8" bushing.

BI Technologies will produce devices outside these specifications to meet customer requirements. Special shaft configurations and additional wire harnesses are also available.

Pricing for the precision potentiometers ranges from $5 to $10 depending on quantity. Lead times are from stock to 6 weeks.
