Rotary Potentiometers, Rheostats

A rotary potentiometer, rheostat, or rotary resistor is a three-terminal resistor with a variable resistance dial or knob that is used to adjust the resistance between two of the terminals. It is an electro-optical device for adjusting the resistance of a resistor network. The 91A1A-B28-B20L model is a rotary potentiometer, rheostat or rotary resistor which is a solid-state device with an integrated circuit surround and a conductive wiper assembly.The 91A1A-B28-B20L is a high voltage, high power unit which is constructed with a screw terminal connection type. It has a physical size of 78x42x17mm, with a surface mounting package for minimal assembly effort. The connection type also ensures tight, reliable connections. The resistance of the 91A1A-B28-B20L is adjustable continuously and can be adjusted over a wide range. The 91A1A-B28-B20L model is also a reliable and durable device which can withstand thermal shock, mechanical wear and electrical noise. Its performance is also resistant to shock and vibration.The 91A1A-B28-B20L has a wide range of applications in industrial, automotive and military applications where adjustable resistance is needed. It is used in circuit protection, precision voltage regulation and other applications. It can also be used in applications requiring high power, such as motor control, automotive electronics and high power LED lighting applications.The main working principle of the 91A1A-B28-B20L is that the resistance is adjustable by means of a variable resistor and the resistance value is adjusted by the user by a rotary dial or knob on the device. The device is a three-terminal device, with one terminal designated as ground and two terminals designated as the adjustable terminals. As the user rotates the dial or knob the resistance changes and is monitored by the voltage level or by some other means. In short, the 91A1A-B28-B20L is a versatile rotary potentiometer, rheostat or rotary resistor which is suitable for use in precise voltage regulation and other applications. This type of device is widely used in industrial, automotive and military applications and is a reliable and durable solution to adjustable resistance requirements. It is easy to install and has a wide range of features, such as adjustable resistance over a wide range, resistance to shock and vibration and resistance to electrical noise. The main working principle of the device is the adjustment of resistance by means of a rotary knob or guide.
