Be sure to read Precautions on page 25.
■ Dimensions
■ Features
Note: All units are in millimeters unless otherwise indicated.
• Incorporates an IC chip with a built-in detector element and amplifier.
• A wide supply voltage range: 4.5 to 16 VDC
• Directly connects with C-MOS and TTL.
• High resolution with a 0.5-mm-wide sensing aperture.
• Dark ON model (EE-SX3088)
• Light ON model (EE-SX4088)
• OMRON’s XK8-series Connectors can be connected to the lead
wires without a PCB. Contact your OMRON representative for information on obtaining XK8-series Connectors.

3. The following illustrations show the definition of response
delay time. The value in the parentheses applies to the EESX4088.
Note: 1. Hysteresis denotes the difference in forward LED
current value, expressed in percentage, calculated
from the respective forward LED currents when the
photo IC in turned from ON to OFF and when the
photo IC in turned from OFF to ON.
