USED
Another very nice A & B potentiometer, pulled from some laboratory test equipment
Tested, no problems at all detected. Track resistance 522.7K with smooth (although log taper) wiper travel.
ALLEN & BRADLEY (A.B) - Rotary Potentiometer
Country of origin is unsure!
One side of the pot has MEXICO printed on it (most likely) and the other side has AUSTRALIA printed on it - go figure! I believe the former is more likely.
Series: MOD POT
Miniature
100K Ohm Log taper
Part #70U1G056R104A
Since Allen-Bradley was purchased by Rockwell International, it is becoming quite difficult to decode some of these part numbers so I have made my own physical measurements below
Type: 8715
300 degree rotation
Panel mounting (supplied with washer & nut)
"Locating tab on one side" to secure in position on the panel
Gold plated SHORT (4.5mm) PCB pins (pulled from a board)
DIMENSIONS:
Shaft: 16mm length x 3.25mm diameter round (no flat spot)
Body: 16mm x 16mm x 14.5mm deep
COSMETIC CONDITION:
Like new
Clean body and "legs" (short though) and undamaged physically
TESTING:
As this is a used component, I have undertaken some basic tests AFTER removal. The track resistance measures 110K and the wiper resistance varys with rotation in a smooth (but logarithmic) fashion with no dead spots observed.
To maintain the condition of this potentiometer, it is now sealed in a clear plastic packet
