Hello Karl,
I'm actually just starting to put together another group buy - this time for vertical PCB-mount pots.
The order will be from Song Huei - http://www.song-huei.com.tw/e_products.htm, and they have a wide range of vertical pots.
The types I'm looking at are all knurled T18 metal shaft:
12mm - R1212N (http://www.song-huei.com.tw/product.php?mode=show&cid=83&pid=325)
Tapers: A = Log, B = linear, C = anti-log,
W = J.I.S. W (A.K.A. 4B, an "S"-shaped curve)
Resistance values: 1kΩ -> 2MΩ
Tolerance: ±20% < 1MΩ, ±30% > 1MΩ
Ratings: 0.08W Linear (B), 0.04W all others.
$0.24 each (except for some uncommon values), Minimum
Order Quantity (MOQ) 1000. These are *really* nice, only
available with machined aluminum shafts, which is the
reason for the price.
16mm - 16K6 (http://www.song-huei.com.tw/product.php?mode=show&cid=15&pid=61)
Tapers: A = Log, B = linear, C = anti-log, D = 10% log,
M = linear, 0-100% resistance over first half of rotation,
N = linear, 100-0% resistance over second half of rotation,
W = J.I.S. W (A.K.A. 4B, an "S"-shaped curve)
Resistance values: 500Ω -> 2MΩ (custom values possible,
I will be ordering some 2.5MΩ eventually)
Tolerance: ±20% < 1MΩ, ±30% > 1MΩ
Ratings: 0.125W Linear (B), 0.06W all others.
$0.16 each (except for some uncommon values), MOQ 1000.
These are similar to the vertical Alphas sold by Small Bear.
The style I am ordering has the 90° bend in the pins at only
13mm from the center of the pot, whereas the Small
Bear ones have the bend at 16mm from the centerline.
I'll be getting B100k & B2.5M. Anybody who wants to join on these or other values is welcome
Best regards,
