Keyence LR-WF10C Full-Spectrum Color Sensor

Keyence LR-WF10C Fiber Color Sensor for Precise Detection

The Keyence LR-WF10C belongs to the LR-W series of self-contained full-spectrum color sensors. This fiber-type unit uses a white LED light source, so it detects subtle color differences on fast-moving production lines. Because the detecting distance and minimum spot diameter depend on the attached fiber head, the LR-WF10C adapts to many mounting setups. Meanwhile, its M12 connector 4-pin design simplifies wiring in tight panels.

Technical Specifications of the LR-WF10C

The Keyence LR-WF10C delivers a selectable response time of 250 µs, 1 ms, 10 ms, 100 ms, or 500 ms. Therefore, engineers can balance speed and stability for each application. The timer supports OFF, ON-delay, OFF-delay, and one-shot modes. In addition, the output type is selectable between NPN open collector and PNP open collector. This output handles 30 VDC or less, 50 mA or less, with residual voltage at 2 V or less. Furthermore, N.O. and N.C. logic are both selectable, which adds flexibility during commissioning.

The external input supports tuning or transmission OFF selection. For communication, connector-type models include IO-Link v1.1 at COM2 (38.4 kbps). However, no built-in ports or expansion ports exist beyond that interface. Besides, the supply voltage ranges from 10 to 30 VDC with 10% ripple (P-P), Class 2 or LPS. Power consumption stays at 50 mA or less (no load) at 24 VDC, and 90 mA or less (no load) at 12 VDC.

Mechanical and Environmental Parameters

The LR-WF10C weighs approximately 95 g. Its protection rating is IP65 under IEC60529, so dust and water spray cause no harm. Operating temperature ranges from -20 to +45 °C with no freezing. In addition, relative humidity must stay between 35 and 85 % RH with no condensation. These ratings suit automotive, packaging, and electronics assembly areas. For instance, the sensor can verify cap color, label presence, or wire jacket shade. Moreover, the white LED source resists ambient light better than many simple color sensors.

Installation Guide for the LR-WF10C

First, mount the fiber head at the correct distance for your target color. Next, connect the M12 4-pin connector to the supply and output circuit. Then, set the response time to match line speed. After that, use the external input or teach button to tune the color reference. Finally, verify NPN or PNP output logic against the controller input card. Keep the cable away from high-voltage drives, because electrical noise can disturb weak color signals. Additionally, confirm the supply stays within 10 to 30 VDC and uses a Class 2 or LPS source.
