HEDT-9000/9100
High Temperature 125°C Two Channel
Optical Incremental Encoder Modules
Data Sheet
Description
The HEDT-9000 and the HEDT-9100 series are high per-
formance, low cost, optical incremental encoder mod-
ules that operate to 125°C. When used with a codewheel,
these modules detect rotary position. The modules con-
sist of a lensed (LED) source and a detector IC enclosed
in a small C-shaped plastic package. Due to a highly
collimated light source and unique photodetector ar-
ray, these modules are extremely tolerant to mounting
misalignment.
The two channel digital outputs and the single 5 V sup-
ply input are accessed through five 0.025 inch square
pins located on 0.1 inch centers.
Standard resolutions for the HEDT-9000 are 500 CPR and
1000 CPR for use with a HEDS-6100 codewheel or equiv-
alent. For the HEDT-9100, standard resolutions between
96 CPR and 512 CPR are available for use with a HEDS-
5120 codewheel or equivalent.
Note: Avago Technologies encoders are not recommended for use in
safety critical applications. Eg. ABS braking systems, power steering, life
support systems and critical care medical equipment. Please contact
sales representative if more clarification is needed.
