EE-SX301/-SX401
I Dimensions
Note: All units are in millimeters unless otherwise indicated.
I Features
• Incorporates an IC chip with a built-in detector element and amplifier.
• 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-SX301); Light ON model (EE-SX401)
• RoHS Compliant.
