Background Suppression Photoelectric Sensor (30~120mm)

Industrial-grade Background Suppression Photoelectric Sensor delivers precise short‑range object detection with an adjustable sensing distance of 30–120mm, depending on operating conditions. This background suppression detection module uses a focused red spot light source and rotary sensitivity control to reliably distinguish targets from surrounding surfaces. Constructed with a durable ABS housing, the industrial optical sensing unit maintains stable operation even under varying colors or background materials. Fast 1ms response performance enables reliable detection in automated production environments such as packaging inspection, electronic assembly, and motion control systems where accurate presence sensing and background rejection are essential.

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.

Adjustable Background Suppression Detection

This optical background suppression sensor provides an adjustable detection distance from 30mm to 120mm using an integrated rotary knob. Precise distance tuning allows reliable target discrimination while minimizing interference from surrounding surfaces. Strong immunity to background color and object reflectivity enables stable detection across various materials. Minimal sensitivity to surface roughness further improves measurement consistency, making this industrial proximity sensing unit suitable for automated equipment that requires dependable short-range object recognition.

Fast Response with Stable Optical Performance

A rapid 1ms response time enables accurate sensing during high-speed automation tasks. The red spot light source forms a focused Ø10mm detection area at a distance of 100mm, providing clear and repeatable detection points. Step detection capability down to 3mm allows precise identification of small positional differences. Reliable optical detection performance supports demanding industrial processes including pick‑and‑place systems, conveyor inspection, and high‑speed sorting equipment.

Industrial Protection and Reliable Operation

This compact industrial photoelectric detection module integrates multiple protection mechanisms including reverse polarity protection, over current protection, and over voltage protection. The plastic housing design ensures durability while maintaining lightweight construction. With IP64 ingress protection and tolerance for indoor lighting up to 20,000 Lux, the sensing unit remains stable in challenging factory environments. Operating temperature support from −20°C to 55°C allows deployment across a wide range of automation installations.

Flexible Output Modes and Clear Status Indicators

Light-On and Dark-On operating modes can be switched through a 10‑second button press, allowing flexible integration into various control systems. LED indicators provide immediate operational feedback: a green indicator shows stable operation while a red LED signals output status during object detection. Adjustable sensitivity combined with visual indicators simplifies setup and calibration in industrial automation workflows.
