Background Suppression Photoelectric Sensor (30~120mm) - แท้จาก DFRobot

INTRODUCTION

Dimension Diagram of Industrial-grade Background Suppression Photoelectric Sensor

Operation (Detection Range Adjustment)

• Factory Default: Pre-set to 30mm detection range. Green LED remains steady; Red LED activates upon detection.
• Adjustment: After securing the sensor, align it with the target object. Turn the knob clockwise until the indicator switches from green to red to set the optimal detection range.

Light-On/Dark-On Mode Switch: Press and hold the button for 10 seconds. Release when the LED color changes to confirm mode switching.

Wiring Instructions of Industrial-grade Background Suppression Photoelectric Sensor

Note: For voltage measurement during installation or maintenance, connect a 1kΩ resistor between the brown (BROWN) and black (BLACK) wires. The output signal can then be measured between the blue (BLUE) and black (BLACK) wires.

Precautions

• Avoid direct exposure to the sensor’s light beam
• Do not expose the sensor’s lens to intense light sources
• Not suitable for detecting mirrored surfaces or specific colors
• If condensation, oil, or dust accumulates on the lens, gently clean it with a dry, lint-free cloth
• Maintain lens cleanliness in dusty or oily environments
• The plastic housing is not impact-resistant; avoid mechanical stress
