renco encoder info

i got three motors with renco encoders on them and found a part
number on the encoder . i e mailed renco for specs for that part
number and this is the info they sent me.
part number 77678-058

hope someone else can use this info .............

Encoder part number 77678-058 = RM21B-1024-1/2-5-CS-LD-C-S
The data sheet is on Internet page http://www.renco.com/106022.htm
Differences from the data sheet:
"B" instead of "D3" means the unit has A, A not, B and B not outputs
only, no Index pulse or Index not.
Performance is only to 85 deg.C (not 100 deg.C) and 100 kHz (not 200
kHz).
"1024" is the resolution in pulses per revolution (possible 4096
quadrature edge counts per revolution)
"CS" is a custom/special cable assembly. The wire colors are the
same as "CA18" on the data sheet, except for Orange and Brown, which
have no connection.
"LD" differential line driver output signals have draw 150mA current
from the +5VDC supply +/-5%.
"S" indicates the unit is special, because of the "CS" cable
assembly.
