Rotary Potentiometers and Rheostats are two different varieties of measuring instruments that allow the user to control the flow of electric current through their associated system. Potentiometers are used to measure voltage and current, and Rheostats are used to regulate current and resistance.

The 81C1A-E28-B15L is one such example of a rotary potentiometer. This device works on the principle of voltage division, where the voltage is divided by the resistance of two interconnected coils. The two coils are connected in series and their resistance is determined by the relative position of the wiper, which is connected to the shaft of the device. The two coils together act as a single, adjustable resistor. Since the voltage is divided unevenly by the two coils, turning the shaft changes the resistance of the system.

The 81C1A-E28-B15L is designed with a robust yet low-profile design that fits into a variety of applications. It is capable of operating in a wide range of temperatures and is highly resistant to shock and vibration. The device also comes with a set of terminals for easy installation, and its shaft is protected by a rubber sleeve to minimize any potential wear. The 81C1A-E28-B15L also offers a wide range of potential applications, from electronics and telecoms to medical equipment and industrial control systems.

Rheostats are used to control current and resistance, and can be used in place of potentiometers when a higher level of power handling is required. Like the 81C1A-E28-B15L, rheostats are composed of two coils which are connected in series. However, unlike the 81C1A-E28-B15L, rheostats do not divide voltage, but instead work on the principle of fixed resistor. As the user turns the shaft of the device, the coils are moved closer together or further apart, in order to increase or decrease the resistance of the system.

Rheostats are typically used in higher power applications, such as in electric motors and heavy-duty electrical systems. They are also often used in medical equipment, where precise manipulation of voltage levels is required. The 81C1A-E28-B15L is not designed to handle the power levels that rheostats are capable of, and should not be used in place of a rheostat for applications requiring higher power levels.

Both rotary potentiometers and rheostats provide a valuable service to the user in controlling the flow of voltage and current in their associated systems. The 81C1A-E28-B15L is an example of a rotary potentiometer, and is designed with a low-profile design for easy integration and installation, as well as a wide range of potential applications. Rheostats, on the other hand, are used in applications where a higher power level is needed.
