In the field of industrial automation and precision manufacturing, KEYENCE's LR-W70C photoelectric sensor has become a critical tool for enhancing production efficiency and quality across numerous industries, thanks to its exceptional performance and flexibility.

Technical Parameters and Data

As a flagship product in KEYENCE's LR-W series, the LR-W70C's technical specifications demonstrate precise responses to high-precision detection demands:

• Detection Distance and Spot Size: Operates stably within 30-70mm, with a minimum spot diameter of just 1.6×2.9mm (at 50mm detection distance), ensuring accurate identification of micro-targets.
• Light Source and Anti-Interference Design: Uses a white LED light source combined with frequency setting functionality (supports up to 2 devices with different frequencies), effectively reducing mutual interference and enhancing detection reliability.
• Response Speed and Timer Functions: Offers multiple response time modes (200μs to 999ms) and supports timer functions like OFF/ON delay and single-pulse, adapting to rapidly changing production line demands.
• Electrical Characteristics: Power voltage range of 10-30VDC, with current consumption as low as 60mA (at 24VDC). Supports NPN/PNP open-collector outputs with a load capacity of 50mA (residual voltage ≤2V).
• Environmental Adaptability: IP65/IP67 rating ensures stable operation in temperatures from -20°C to 50°C, 35%-85% humidity, and 1000m/s² shock environments. A metal housing (zinc die-cast with nickel-chrome plating) further enhances durability.
