HEDS-9100 HP [Agilent(Hewlett-Packard)], HEDS-9100 Datasheet - Page 4

• Manufacturer Part Number: HEDS-9100
• Description: Two Channel High Resolution Optical Incremental Encoder Modules
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Electrical Characteristics
Electrical Characteristics over Recommended Operating Range, typical at 25 C.
Encoding Characteristics
Encoding Characteristics over Recommended Operating Range and Recommended Mounting Tolerances.
These Characteristics do not include codewheel/codestrip contribution. The Typical Values are averages over
the full rotation of the codewheel. For operation above 100 kHz, see frequency derating curves.
Note: Module mounted on tolerance circle of
k pull-up resistors used on all encoder module outputs.
Frequency Derating Curves
Typical performance over extended operating range. These curves were derived using a 25 pF load with a 3.3
k pull-up resistor. Greater load capacitances will cause more error than shown in these graphs.
