EE-SY169B
Be sure to read Precautions on page 24.
■ Dimensions
■ Features
Note: All units are in millimeters unless otherwise indicated.
• High-quality model with plastic lenses.
• Highly precise sensing range with a tolerance of ±0.6 mm horizontally and vertically.
• With a red LED sensing dyestuff-type links.
• Limited reflective model
• Higher gain than EE-SY169.
• Possible to get the same IL as EE-SY169 with IF=10 mA. (half of
EE-SY169 condition)
• Recommended sensing distance = 4.0 mm
