120 EE-SX3070/-SX4070 Photomicrosensor (Transmissive)
Photomicrosensor (Transmissive)
EE-SX3070/-SX4070
■ Dimensions
Note: All units are in millimeters unless otherwise indicated.
■ Features
• Incorporates an IC chip with a built-in detector element and ampli-
fier.
• Incorporates a detector element with a built-in temperature com-
pensation circuit.
• 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-SX3070)
• Light ON model (EE-SX4070)
■ Absolute Maximum Ratings (Ta = 25°C)
Note: 1. Refer to the temperature rating chart if the ambient temper-
ature exceeds 25°C.
2. Complete soldering within 10 seconds.
