Dual Channel Encoder
OPB822S, OPB822SD
OPB826S, OPB826SD
Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/癈 above 25?C.
(3) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons    
and ketones. Spray and wipe; do not submerge
.
(4) Derate linearly 3.33 mW/癈 above 25?C.
(5) All parameters tested using pulse techniques.
(6) Feature controlled at body.
