BACKGROUND:
Ex TEPCO BOP 50-8M Bipolar Power Supply (fully functioning but it has now become an "organ donor")
BOURNS - Rotary Potentiometer
Type: 3590S series
Value: 20K
5% tolerance
Linearity: +/- 0.25%
Taper: Linear
10 turn with stops each end
Panel mounting (supplied with nut & washer)
Round 1/4" shaft (not a D shape with flat spot) with a slot at the end of the shaft. Fine for use with a grub screw or collet fixing knob or just leave it "as is" for through hole screw driver adjustment.
DIMENSIONS:
Body: 22.5mm diameter x 18.5mm height
Panel mounting hole required: minimum 9.5mm
Shaft length: 12.25mm
Side mounted solder tag terminations
COSMETIC CONDITION:
USED
Clean and undamaged physically
Solder tags have been cleaned and "dags" removed
TESTING:
Being a USED potentiometer,
Measured track resistance: 20.13K Ohm
NO issues with linearity that I could observe and no dead spots detected - nice smooth variation across the track.
To maintain the condition of this potentiometer, it has now been sealed in a clear plastic packet
