specific ALPS encoder part #

Parts Questions

hello there

i am gathering parts to build the sid control unit. i have not used rotary encoders before. it seems like the ALPS ones are popular. is there a specific resolution or # of detents that are needed. it seems like 15 res / 30 detents is the standard. ALPS makes the EC11B series in many flavors - some have push-on switches - some don’t. any assistance in helping me hone in on the right one would be much appreciated.

would this one work ?

i think u prolly want the un-detented ones - for smoothless operation :wink:

the number of pulses doesn’t really matter - it’ll only effect how the param ur controlling will change with the amount of turn u apply to the encoder…i think ;p

u could use one with switches - ud just connect these pins to the DIN like with regular switches - just make sure they’re momentary type…
