Installation Guide

• Mount the sensor on a rigid bracket and aim it directly at the target surface. No reflector or second unit is required.
• Tighten mounting screws to 0.5 N·m maximum to protect the glass-fiber reinforced PBT housing.
• Connect the M8 connector to a 10–30 VDC supply. Wire the NPN open collector output to a sinking load.
• Turn the 1-turn trimmer to set sensitivity against your actual target material and color.
• Choose LIGHT-ON or DARK-ON with the mode switch before commissioning.
• For side-by-side mounting, install no more than 2 units and enable polarization filters or the automatic different frequency function.
