Title: Rotary encoder shaft size
Post by: ItsDaPlumber on August 26, 2013, 04:01:20 pm
Was wondering what size hole i need for the shaft of the rotary encoder.

most rotary encoder from ebay ( the one with blue base http://www.ebay.com.au/itm/10pcs-12mm-Rotary-Encoder-Switch-with-Keyswitch-New-/110706468028?pt=AU_B_I_Electrical_Test_Equipment&hash=item19c69ea4bc&_uhb=1) a 7mm hole should be enough, but they are a pain to wire because the distance between each pins are very close and they don' t have the best feel. price though can't be beaten

The one from leo bodnar or CTS branded ones, have a much nicer in quality and feel , and the hole size is 9.7mm or 10mm, it's easy to solder and wire, cons: Price.

I used both, the ebay ones are ok for volume chat, spotter, black box etc, but for bias knob , since I want to feel distinct notch each turn in Bias, I used CTS one.

Your the man!!! Thanks for the info. So, what am i looking for inperticular when looking for a rotary encoder? 16 detents? 20 detents? 4 bit or 2 bit? Can i use an illuminated rotary encoder?

diameter of the shaft is 6mm, so I would make a 8-9 mm hole.

no worries :)
16 Dents or 20 dents per revolution all works well, Im not sure if I have seen illuminated encoders before. so I'm not sure if the led from the encoders can be wired into the PCB, it should work, but I can never get the led  of my toggle switch to work properly when switch on so I ended up not wiring it .

Yes. The LED/Illumination portion should be separate from the actual encoder. You can connect this to a DLC247 as an indicator, or to the power output from a Pro Gauge, if you use a resistor to limit current, to have it permanently lit.

Well im not sure if anyone make an illuminated push button switch. I can use a toggle switch for the Mic Mute. I can find those that light up.
