HEDS-5545 AVAGO [AVAGO TECHNOLOGIES LIMITED], HEDS-5545 Datasheet - Page 5

• Manufacturer Part Number: HEDS-5545
• Description: Quick Assembly Two and Three Channel Optical Encoders
• Manufacturer: AVAGO [AVAGO TECHNOLOGIES LIMITED]

Recommended Operating Conditions
Note: The module performance is guaranteed to 100 kHz but can operate at higher frequencies. 2.7 k pull-up resistors
required for HEDS-5540 and 5640.
Encoding Characteristics
Encoding Characteristics over Recommended Operating Range and Recommended Mounting Tolerances
unless otherwise specified. Values are for the worst error over the full rotation.
Note: See Mechanical Characteristics for mounting tolerances.
