PILZ FB/F11/180SEK.

The FB/F11/180SEK is a potentiometer with a time-based feature, where "180SEK" likely refers to 180 seconds (or 3 minutes). This suggests the potentiometer is designed for applications requiring a controlled adjustment or delay over a 3-minute period. It is typically used in circuits that need gradual, time-dependent resistance changes, such as in dimming controls, timers, or other electronic systems that require slow, precise adjustments over a set duration. The FB/F11/180SEK is ideal for applications where such a gradual change is crucial for performance, such as in industrial or consumer electronics that involve time-sensitive control.
