HEDS-9040 HP [Agilent(Hewlett-Packard)], HEDS-9040 Datasheet - Page 4

• Manufacturer Part Number: HEDS-9040
• Description: Three Channel Optical Incremental Encoder Modules
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Recommended Operating Conditions
Note: The module performance is guaranteed to 100 kHz but can operate at higher frequencies. For the HEDS-9040 #T00 for operation
below 0 C and greater than 50 kHz the maximum Pulse Width and Logic State Width errors are 60 e.
Encoding Characteristics
HEDS-9040 (except #T00), HEDS-9140
Encoding Characteristics over Recommended Operating Range and Recommended Mounting Tolerances
unless otherwise specified. Values are for the worst error over the full rotation of HEDS-5140 and HEDS-
6140 codewheels.
