00:57The push button means one component does select and scroll. At this price you burn one and don't care.
01:05Number 2, the KY040 Rotary Encoder Module. $4.43, 3860 sold, 4.9 stars. Same 20 pulse, 360 degree action,
01:185 volt, with push button.
01:20Difference is the breakout board, it already has the pull-up resistors and the header pins done for you.
01:26If you're wiring an Arduino menu or a volume control and you don't want to think about debounce hardware, this
01:32is the plug-and-play one.
01:33Cheap enough to keep a stack in the drawer.
01:37Number 3, the E6B2CWZ6C, $8.96, 3557 sold, 4.8 stars.
01:46This is where you leave toy territory. It's an industrial 5 to 24-volt DC encoder, NPN output, 2-meter
01:53cable, and it comes in every resolution from 10 up to 1,200 pulses per revolution.
01:59For a CNC build, this is the one you bolt onto a spindle for RPM feedback or onto a ball
02:04screw for position.
02:06Real shaft, real housing, real cable strain relief.
02:10Dirt cheap for a sealed industrial body.
02:13Number 4, the standalone EC11, $1.82, 5 pins, 20 positions, 20 pulse, push button, your choice of 15 or
02:2220-millimeter shaft.
02:242,871 sold, 4.9 stars.
02:28This is the bare component, no PCB, just the encoder itself.
02:33Buy it when you've already designed your own board or your wiring point-to-point.
02:38Cheapest functional encoder here, and for panel-mounted jog dials on a budget CNC controller it does exactly what the
02:44$4 version does.
02:46Number 5, the 38S6G5BG24N photoelectric incremental encoder.
02:521252, 2,772 sold, 4.9 stars.
02:58Optical, not mechanical, so no contact wear, no mist counts at speed.
03:02AB two-phase quadrature, DC 8 to 24 volts, NPN or PNP output, and you pick the resolution, 50 up
03:10to 600 PPR.
03:11This is the upgrade pick, throw it on a spindle for accurate RPM or on a stepper for closed-loop
03:17feedback.
03:18Under $13 for optical sensing is genuinely silly.
03:23Links to every one of these are in the description, with the exact resolution and shaft size options spelled out
03:28so you don't order the wrong variant.
03:30If this saved you an hour of spec hunting, hit like and subscribe, more CNC parts breakdowns coming, and I
03:36only feature stuff I'd actually bolt to my own machine.
