Centralab WW-500 Potentiometer 50 Ohms Rotary Panel Mount

Centralab WN500 is a 50-ohm, wirewound rotary potentiometer designed for panel mounting, delivering a precise 0–50 Ω range in a single-turn, linear-taper design. It is rated for 5 W and uses solder-terminal connections for straightforward installation. The compact body measures about 1.16 inches in diameter and 1.32 inches tall, with a 0.375-inch panel bushing and a round knurled shaft 0.25 inches in diameter for dependable manual adjustment. Its resistance tolerance is ±10%, making it suitable as a fixed-low-value attenuator or calibration element in instrument panels, test gear, and control consoles where a reliable, low-resistance setting is required. The unit's panel-mount configuration and lug-style terminals support robust wiring in environments where space is tight and vibration is a consideration.
