electronics BI Technologies' Model P270 27mm rotary potentiometer has been specified for use by manufacturers in industrial, commercial, audio and heavy equipment markets. Since production began nearly a year ago, BI has been awarded four major design wins with the versatile rotary potentiometer.

"The multipurpose design of the P270 device lends itself for use in heavy-duty equipment as well as light panel applications," said Alain Leon, variable products applications engineer for BI Technologies. "With the extended life cycle to 1 million rotations and multiple design options including package sealing, and center-tap and two gangs for redundancy, the potentiometer is ideal for applications ranging from electric guitars to industrial lifts."

Recent design wins for the P270 potentiometer include industrial scissor lifts to raise and lower platforms and heavy duty welders; custom-built scooter controls with special short angle and sealing elements to protect against harsh environments; throttle assemblies in vehicles, directional speed controls for forklifts, and material handling equipment; and a win with a premier guitar manufacturer due to the potentiometer's superior rotational consistency and custom non-linear tapers.

The Model P270 rotary potentiometer features a resistance range of 1k? to 1M ? and standard tolerance to 10 percent. Power ratings are 2W at 70C, with a maximum input voltage of 500Vdc and dielectric strength of 1000VAC. Operating temperature range is -55C to +120 C. BI Technologies will produce devices outside these specifications to meet customer requirements.

Typical pricing for the Model P270 potentiometer ranges from $4.00 to $6.00 each. Samples are available within 2-3 weeks and production lead-time is 4-5 weeks.
