Rotary Potentiometers, Rheostats, and the PTV112-3412A-A204 are three very popular electrical components used in many electronic systems. The way they work is similar, but there are some key differences between the three. In this blog post, we will review their applications and working principles.

Rotary Potentiometers

Rotary Potentiometers or Potentiometers are commonly used as electronically variable resistors. They are used to adjust or control levels of electrical currents and voltages, or as a position and speed detector. Some of the applications where Potentiometers are used include medical equipment, audio equipment, measurement and control systems, automotive systems, instrumentation, and others. Potentiometers have two end terminals and one wiper terminal. A sliding contact or wiper is connected to the resistance element, and when rotated by a knob on the rotary shaft the wiper makes contact with the resistance element. This type of connection is known as a potentiometric connection, and this is what makes the Potentiometer work. As the wiper moves along the resistance element the current going from one end terminal to the other end terminal will decrease or increase depending on the movement of the wiper.

Rheostats

Rheostats are variable resistors that are used to adjust electric current. They are made up of a resistor with two end terminals and a wiper that slides along the resistor. As the wiper moves along the resistor the current going from one terminal to the other will decrease or increase depending on the resistance of the resistor. Rheostats are used in a variety of applications, including controlling current in motors, lamps, and other applications where the current needs to be adjusted. They are also used in circuits to adjust the voltage divider bias in amplifiers and to adjust the gain of an audio amplifier.

The PTV112-3412A-A204 is a rotary potentiometer of the two-wire type. It is typically mounted on a PCB with an encoder motor attached to its outer housing. It has two end terminals and one wiper terminal. The wiper can move along the resistance element electrically, allowing the current passing from one end terminal to the other to be adjusted and controlled. A major application of the PTV112-3412A-A204 is in the medical field, specifically in the control of electric current in medical devices. In addition, the PTV112-3412A-A204 is also used in audio equipment, measurement and control systems, and instrumentation.

Conclusion

Rotary Potentiometers, Rheostats, and the PTV112-3412A-A204 are three very popular components found in many electronic systems. Although their working principles are similar, each has their own unique applications and uses. Potentiometers are used mainly as adjustable resistors or as position and speed detectors. Rheostats are used to adjust current in motor circuits, lamps, and other applications that require current adjustment. The PTV112-3412A-A204 is a rotary potentiometer that is used in medical and audio equipment, as well as in objectives for measuring and controlling systems.
