KEYENCE LR-W70C Digital Fiber Optic Sensor M12 4pin

KEYENCE LR-W70C Small/Dual Spot Type M12 connector 4pin type:

The Keyence LR-W70C is a compact digital fiber optic sensor designed for precise detection in industrial automation. Part of the LR-W series, this model utilizes a white LED light source to achieve accurate color differentiation and stable detection, even under varying environmental conditions. It supports a detection range of 30 mm to 70 mm, making it suitable for applications requiring small-spot detection. The sensor features a durable M12 connector with IP65/IP67 environmental protection, ensuring reliability in harsh environments.

The LR-W70C offers flexible output configurations, including NPN and PNP transistor logic, with a maximum output current of 50 mA. It supports multiple response times (200 µs to 500 ms) and timer functions (OFF/ON-delay, single-pulse) to adapt to different operational needs. Advanced features include mutual interference prevention (up to 2 units) and IO-Link compatibility for seamless integration into automated systems. Its intuitive interface and compact design enhance usability, while the zinc-cast housing with nickel-chromium plating ensures long-term stability.
