Its dual-spot system enhances stability and minimizes interference from surface irregularities or environmental lighting changes. The unit supports both NPN and PNP open-collector outputs with selectable NO/NC configurations, making it compatible with a wide range of automation systems. Its rugged, corrosion-resistant design ensures long-term performance in environments exposed to dust, moisture, and vibration. Key Features: Full-Spectrum White LED: Detects color, contrast, and intensity variations with superior precision. Dual-Spot Optical System: Enhances detection accuracy and minimizes influence from surface variations. Flexible Output: Selectable NPN/PNP, NO/NC configuration for easy integration. Fast Response Time: Adjustable from 200 μs to 999 ms to match application requirements. Simple Configuration: One-touch tuning with selectable delay and one-shot timer functions. Compact and Durable: Zinc die-cast housing with nickel-chrome plating for corrosion resistance. Wide Power Range: Operates on 10–30 VDC with low current consumption. Environmental Protection: IP65/IP67-rated for water and dust resistance. High Ambient Light Immunity: Operates reliably under sunlight up to 20,000 lux. Vibration and Shock Resistant: Built to withstand 1000 m/s² impact and continuous industrial vibration. The LR-W70C is ideal for applications such as packaging inspection, part differentiation, label verification, and assembly automation.
