Potentiometer life cycle is 2 million rotations

The Model P232 potentiometer is sealed to withstand harsh environments, allowing it to meet the most stringent life requirements.

Providing design engineers with a robust rotary device designed to withstand harsh environments, BI Technologies Electronic Components Division has developed a 24mm rotary potentiometer with a life cycle of 2 million rotations.

According to Barbara Wiesinger, director of product development for BI Technologies Electronic Components Division, the 24mm rotary potentiometers were originally offered with a rotational life of 10k to 100k cycles.

"We enhanced the design by adding a CP element and improved contact spring, allowing for a more robust end product", says Wiesinger.

The Model P232 potentiometer is also sealed to withstand harsh environments, allowing it to meet the most stringent life requirements, particularly those in industrial applications.

Typical applications for the Model P232 potentiometer include joysticks, foot pedals, industrial controls, position sensors and board mounted panel controls.

The Model P232 potentiometer features a resistance range of 1kOhm to 1MOhm and standard tolerance to +/-10%.

Maximum input voltage is 200V DC, with a dielectric strength of 500V AC.

Operating temperature range is -10 to +85C.

BI Technologies will also produce devices outside these specifications to meet customer requirements.

The RoHS-compliant rotary potentiometer features dual-gang availability along with both linear and audio tapers.

BI will also develop gears, special shaft configurations or electrical outputs upon request.

Typical pricing for a standard Model P232 rotary potentiometer ranges from $2.50 to $4.00 depending on volume.

Lead times are from stock to 5 weeks, with custom samples available in as few as 2 weeks.
