E3S-A Safety Precautions WARNING This product is not designed or rated for ensuring safety of persons. Do not use it for such purposes. Precautions for Correct Use Do not use the product in atmospheres or environments that exceed product ratings. Mounting Position of Optical Axis of Through-beam Model Unlike conventional through-beam sensors, the E3S-A Through-beam Photoelectric Sensor incorporates 2 lenses. The lens actually in use is the one marked with an arrow indicating the position of the optical axis. When using a Slit, attach it to the lens marked with the arrow. Mounting Bracket (Provided)...
