Re: Bridgeport retrofit servo questions

Luke,
This encoder from US Digital looks like it will do the job: E6S-2000-
625-PKG1

Here's the breakdown of the part#:
E6S - series number
2000 - CPR
625 - 5/8" shaft
PKG1 - includes hex key and spacer tool

I like this one over the E3 because it has a nice snap-in connector
on it. Yes, you're paying a little more for it, but I think that
since they sell the shielded cable ready to go, it makes life a lot
easier and makes for a cleaner/reliable installation.

The price breakdown is this:
Base price for E6S = $49.

>= 2000 CPR add $8.82 (because it is HiRes)

5/8" shaft add $12 (because it is an oddball size..or most popular
size depending on your perspective)
PKG1 add $3 (only need one)...so 1 PN would be E6S-2000-625-PKG1 and
the other 2 E6S-2000-625
------------------------------
Total for each encoder = $69.82 X 3 = $209.46 + $3 for PKG1 = 212.46

Now to the cables:

CA-3131-6FT - 6ft cable w/ connector on one end, shielded round
conduit and no connector on other end.

$10 ea X 3 needed = $30. Also offer custom lengths if 6' isn't long
enough...not cheap I know, but done right. This is not an area where
I want problems!

GRAND TOTAL for encoders w/cables:
$242.46 + shipping

Quite a hidden cost in the retrofit...costs more than the motors! Now
I know why people say encoders are so expensive.
