OPTICAL: This is a very nice heavy
duty optical rotary encoder. These are removed from equipment, in
excellent condition. Oak Grisby. There is a 4 conductor cable terminated with a 2mm connector.
We also include a 4 pos 2mm hright angel header for the PCB.
The Aug 2009 version of the DDS PCB has a place to solder the 4 pin 2mm header.
This is a very smooth operating encoder, you need to set the parameters via the serial port to turn off
the debounce and delays because it's very fast, and clean electrically.
[ Hook up instructions ]
There is no push switch.
The price is $12.99 with the FULL DDS kit. In leiu of standard encoder.
Connector, header for PCB, and Mounting hardware (nut and washer) included, see photo above
The middle one in the top photo is a mechanical encoder with
detents, no push switch. Fits into PCB. Bournes #
- No longer avaiable -
NORMAL: The one on the right in the top photo is the encoder I originally designed the
board for and have been shipping with all kits. It's a smooth
turning mechanical encoder with push switch. There is some
contact bounce but the micro is programmed for this, but the action is
less precise as a result. The push switch normally controls the
speed. Bournes # PEC11-4020F-S0024 This one is inclued in the Full Kit. Mounting hardware included (nut and washer)
NOTE: Encoders are only availbe with a DDS kit, I am not offering them seperatley.
A note about the push switch: There are a total of 3 switches on the DDS
board, normally the push switch on the encoder controls speed, and the
other two are memory up and down. If you buy one of the other
encoders without a push switch you can either install a separate
pushbutton switch, or reassign one of the other switches, and only use
one switch for memory up (it rolls at M#9) Ideally if you are
mounting switch on a front panel, get a (on)-off-(on) momentary
toggle switch and use that for the memories, it works very nice that
way, then a separate pushbutton for encoder speed.
