Introduction Quick Response Center The “heart” of the Bourns Sensors and Controls operation located in Tijuana, Mexico, is the Quick Response Center (QRC). The QRC employs a technical base of engineers, technicians, and production personnel to process all customer inquiries and sample requests. Producing samples with modied features for application specic requirements in a relatively short time is the main focus of the QRC. By utilizing the sustaining engineering and fabrication departments, the QRC can modify parts produced to customer specications and coordinate sample fabrication in production...

Introduction Reliability Test Facility Once our engineering team has developed a product design, the Reliability Test Facility takes a major role to insure performance standards. The lab is equipped with specialized test equipment designed to run for thousands of hours, providing environmental, electrical and mechanical testing of potentiometers and encoders. Humidity, salt spray, rotational cycling, and exposure to high and low temperature extremes are just a few of the specialized tests performed on our products. In addition to testing nished products, our lab is set up to test individual piece...

No other manufacturer offers a broader selection of potentiometers than Bourns Sensors and Controls. Types of potentiometers in the Sensors and Controls product line include: • Multiturn Precision • Single-Turn Precision • Panel Control • Commercial Grade Precision Potentiometers are...

Potentiometers Wirewound Element Technology Wirewound elements offer good stability, excellent linearity, low noise, high power capabilities and good operational life. Wirewound elements offer a wide range of resistance values up to 500 kΩ. One primary limitation of wirewound elements is the nite resolution steps, which result from the wiper moving from turn to turn perpendicular to the coil of wire. (These steps are distinct, sudden, repeatable changes in output.) Resolution improves as resistance values increase due to the manufacturing processes whereby smaller diameter wire and a higher number...
