Skip to product information
These are new items and come with a nut and a washer for mounting on a front panel. The T18 splined shaft is 6mm diameter. The mounting hole required is 7mm diameter. The connection pins will allow either PCB mounting or soldered wire connections. The "A" prefix before the track resistance value denotes a logarithmic audio track taper intended for direct analogue audio volume control. The max power rating is 0.1W.
The length of the turning part of the shaft varies between 8 and 12mm depending on the particular track resistance. The length of the threaded part of the shaft is 6mm.
If you have a pot with a track label of A503, this is an A50K where 3 is the number of zeros after 50 in Ohms. A 502 would be 5K, a 472 would be 4K7 etc. Sometimes pots may also be labelled with the A as a suffix e.g. 50KA.
