Rotary potentiometers, also known as rotary resistors, are variables of resistive components, which have three terminals. The PCB in such a potentiometer consists of a resistance track that is usually divided into the starting resistance point and the end resistance point. The wiper is connected to a rotating mechanical shaft, and when the shaft turns, the resistance between the wiper and the end point of the track also changes; in other words, the amount of resistance between the two is varied. The third terminal is the ground, and its purpose is to provide a reference voltage.Rotary potentiometers come in various sizes and shapes, and are mainly used for controlling the gain of electronic signals, such as in volume and tone controls. They are also used as analog position controllers in toys, appliances, and other consumer products.PCW1J-R24-BAB103L is one of the many rotary potentiometers available. It is a panel-mount type potentiometer with a round slider. The PCB is made of silver-palladium alloy and the resistor element is formed by a rectangular spiral element. The PCW1J-R24-BAB103L has a continuous rotation angle of 280 degrees and its torque is 0.12N•m (max). It has a resistance value of 10k ohms and a sliding linearity of ±2%. Furthermore, it features a maximum resistant voltage of 6V” and has an operating temperature range from -30°C to +85°C.The PCW1J-R24-BAB103L is mainly used in controlling operations and incrementing parameters in basic audio systems, including personal computers, music systems, computer sound cards, gaming devices, etc.Rheostats are also a type of variable resistor. While similar in form to potentiometers, they work on a different principle. Whereas the output voltage of a regular potentiometer is proportional to the angle of the wiper, rheostats output a voltage that is proportional to the amount of resistance placed in the circuit.Unlike a potentiometer, a rheostat only has two terminals; a wiper, which is connected to a sliding contact, and a stationary contact. When the sliding contact is moved between the two terminals, it increases the resistance in the circuit, thus decreasing the voltage. As such, rheostats are mainly used for controlling the current flowing in a circuit.Although not very common in consumer products, rheostats are used in a wide range of applications, such as control circuits, light dimmers, motor controls, and relays. They are also used in precision measurement devices and laboratory instruments, such as voltmeters, ammeters, and Wheatstone bridges.In conclusion, both rotary potentiometers and rheostats are essential components in a wide range of applications, from consumer products to industrial equipment. While both can be used for controlling the voltage or current in a circuit, the way in which they work is very different; one being angular based, and the other being properly based. The PCW1J-R24-BAB103L potentiometer is a reliable and versatile component, suitable for various audio applications.
