Bourns is a Riverside, California-based manufacturer of electronic components founded in 1947, producing a broad portfolio of sensors, potentiometers, resistors, inductors, circuit protection devices, and encoders for automotive, industrial, medical, and consumer electronics applications worldwide. Within the encoder category, Bourns manufactures incremental and absolute optical encoders, panel-mount mechanical encoders, and encoder switches, with products used in motor position feedback, human-machine interface controls, industrial test equipment, audio and consumer devices, and medical instrumentation. Bourns encoders are widely available through distribution channels including Digi-Key, Mouser, and Arrow, and are commonly specified by engineers who need compact, cost-effective encoder solutions for control panel, HMI, and light-duty motion feedback applications alongside a full suite of complementary passive components from a single supplier.
