Dual Rotary Encoder Pulse values ?

Hi everyone,

I'm considering buying a 5-piece pack of dual rotary encoders from eBay:

5PCS EC11EBB24C03 Dual Axis Encoder with Switch 30 Positioning Number 15 P

There are other Pulse values on offer with the same encoder such as:

PU V2R2

Pulse

Pulse P Z9F3

Pulse PY-4B9

Pulse B6G1

and so on....

Does anyone know what this means and whether it really matters for a cockpit sim build or if any pulse is preferable.

I would be using them initially for G1000 nxi prototype. There is little difference in the price however they are from different sellers.

Cheers,

Rob
