Hi Ya,
I'm looking at the Digi-Key catalog (also availible at
http://www.digikey.com) and they have several flavors of rotary encoders
from $3.38 (24 pulses/360 degree mechanical encoder) to $41.20 (128
pulses/360 degree optical encoder) with the cheapest optical encoder
coming in at $18.86 for either 16 or 32 pulses per revolution.
The hall effect sensors run anywhere from $.75 to $1.75 in a wide
variety of flavors for different strengths of magnets ($1.17 - $4.55
depending on strength).
All this and much more in a good catalog that can be had for free. The
only problem is they have a $25 min order or else they hit you with a $5
fee. If you make the $25 min order the shipping is free (UPS ground).
I say this not as a rep of Digi-Key but as a past customer. If they
ain't got it, you don't need it. They are fast and acurate on small
orders.
C Ya!

| I've found the Hall Effect switches that All Electronics sells to be quite useful. Their part number is the HESW-2 and they are 75 cents each, or 10 for $6.50. (100 for $60.00). They are easily activated by the micro magnets that Radio Shack sells (...) (28 years ago, 15-Jun-96, to lugnet.robotics.handyboard)
