Potentiometers, rheostats and trimmers are three-terminal resistors that are used to measure or divide voltages, and to protect or control circuits

Linear potentiometers are sensors that produce a resistance output proportional to the displacement or position

Digital potentiometers are three-terminal resistors with an adjustable center connection. To set the output resistance, a digital signal is sent through an electrical interface

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas.

Rotary position sensors include potentiometers, resolvers and a variety of magnetic and capacitive technologies. Sensors are designed for angular displacement less than one turn or for multiturn displacement

Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC). 

Control knobs are used for the control or adjustment of electronic or electrical devices.

Cable extension linear position sensors are used to measure the movement and displacement of objects. A cable or wire is attached to an object, and as the object moves, the transducer produces an electrical signal proportional to the wire's linear extension.

Industrial knobs are small, usually round, devices that are designed for use on industrial machinery, electronic components, and metal cabinetry. They are usually made out of metal, plastic, or rubber and are available in a variety of sizes, colors, and finishes.

Audio transducers and buzzers are used in electronic equipment, toys and various warning devices as the sounding component.

Audio recorders / voice loggers are used to locate, retrieve, duplicate and/or distribute audio voice or data information from single system environments to large multi-channel networked systems.

Audio switch matrices are electronic switching instruments for interfacing audio signals in scanning, recording and analysis systems.

Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies, receptacles, and battery packs. 

Decade boxes and dividers provide highly accurate and digitally variable standard values of resistance, capacitance, inductance, voltage and/or current for calibration, comparison and testing.

Audio mixers and consoles are units that combine signals from microphones and/or line level sources to produce a combined signal or signals.
