Installation Guide

• Mount the sensor through the mounting hole and tighten to 0.5 N·m maximum.
• Route the M12 pigtail away from high-current cables to reduce electrical noise.
• Set the single-turn trimmer to adjust sensitivity for your target material and color.
• Select LIGHT-ON or DARK-ON mode to match your control logic before wiring.
• Keep the sensing face clean and avoid mounting near strong ambient light sources.
• Maintain at least 300 mm between units when using two sensors side by side.
