This part is used in Shure Mic Products it’s used to turn up and down the volume on a transmitter. I have found similar items but I’m not 100%. I have attached pictures of the part. It’s missing the 6 Pins that point straight down. It’s important that the shaft has a nocte in to for a volume knob to fit on. Thank you in advanced for any help!
Hello @mike907
This is likely a Bourns PTD90 Series potentiometer. I will assume it is this part PTD902-2015F-A103-ND.
For reference, that “05A10K” marking on the body breaks down as:
- 05A = Bourns’ taper code for the A-series curve, which is a logarithmic (audio) taper
- 10K = Resistance value
Before ordering, please pull up the datasheet and double-check the dimensions and pin configuration against your actual part, since there are several similar variants in this series (different shaft lengths, gang counts, and taper options) that look nearly identical from the outside.
