Function

Detailed Description

Background-Suppressed Detection

Eliminates false triggers from distant backgrounds by focusing on targets within the 4–180 mm range, ensuring accurate detection even in cluttered industrial settings.

Adjustable Sensing Range

5-turn potentiometer allows precise calibration of the sensing distance, adapting to different target sizes, reflectivities, and installation requirements.

NPN Digital Output

Delivers a stable NPN light-on (NO) output with a maximum current capacity of 100 mA, enabling direct connection to PLCs, relays, and control systems for real-time process automation.

High-Speed Detection

Response time of less than 0.5 ms and switching frequency of 1,000 Hz support reliable detection of fast-moving objects on high-throughput production lines.

Visible Light Alignment

650 nm visible red PinPoint LED provides a clear, focused light spot (Ø6.5 mm at 150 mm), simplifying on-site installation and alignment with targets.

3. Technical Features

Background Suppression Technology: Advanced optical design ignores background reflections, enabling precise target detection without interference from surrounding surfaces (e.g., conveyor frames, walls), even for semi-transparent workpieces.

PinPoint LED Light Source: 650 nm visible red LED provides a concentrated light beam with a long service life (≥100,000 hours at 25°C), ensuring consistent performance and reducing replacement frequency in continuous operation.

Miniature Slim Design: Compact rectangular housing (12.2 mm × 41.8 mm × 17.3 mm) fits into tight installation spaces, making it ideal for compact machinery, dense automation setups, and robotic end-effectors.

User-Friendly Calibration: 5-turn potentiometer allows fine-tuning of the sensing range, facilitating quick on-site setup and adaptation to varying target reflectivities and installation distances without complex tools.

Comprehensive Electrical Protection: Integrated protection against short circuits, overloads, and reverse polarity safeguards the sensor and connected equipment from electrical damage, extending overall system service life.

Wide Voltage Compatibility: Operates on 10–30V DC power with residual ripple ≤5 Vss, ensuring seamless integration with standard industrial power systems and flexible deployment across diverse automation setups.

Durable Material Selection: ABS plastic housing and PMMA (acrylic) optical lens offer excellent mechanical strength, scratch resistance, and resistance to industrial contaminants, ensuring long-term reliability in harsh environments.

Flexible Cabling: 2-meter 3-core PVC cable (Ø3.4 mm, 0.14 mm² cross-section) allows easy routing and connection; note to avoid bending below 0°C to protect cable integrity and ensure stable signal transmission.
