Panel Mount Resistor: A style of resistor that mounts to a panel, normally an adjustable resistor or potentiometer. Types of Panel Mount Adjustable Resistors are shown below.
The adjustment resistors with the rectangular body are defined in MIL-PRF-22097 as 1 watt with a 17 turn minimum or 27 turns maximum electrical travel;

The maximum voltage is 400 volts,
The temperature range; -55C to +150C [1 watt at 70C].
Also refer to Drawing 86097 -001.

Potentiometer: A variable resistor. Designed for frequent changes, a volume control. The output of a Potentiometer is a voltage that is variable depending upon the position of the wiper contact. The potentiometer is commonly referred to as a variable voltage divider. It, in effect, converts mechanical information into an electrical signal. Companies that Manufacturer Potentiometers.
