Keyence LR-W500C LR-W Series Self-Contained Full-Spectrum Photoelectric Sensor M12 Connector 500mm

Keyence LR-W500C is a self-contained full-spectrum photoelectric sensor with a 30 to 500 mm detection range. White LED light source with adjustable beam spot. M12 4-pin connector type. NPN/PNP output selectable. IP65/IP67 rated zinc die-cast metal housing. IO-Link V1.1/COM2 (38.4 kbps) compatible. Designed for detection of colour, surface finish, and appearance variations in demanding industrial environments.

Applications:

• Product differentiation based on colour and surface finish

• Registration mark detection on film, labels, and curved surfaces

System Integration:

• This sensor belongs to the Keyence LR‑W series of self‑contained full‑spectrum photoelectric sensors.

• Selectable NPN or PNP output in the same unit simplifies standardization across different machine types.

• M12 4‑pin connector mates with standard industrial M12 female cables; quick disconnect option simplifies installation and replacement.

• IO‑Link V1.1/COM2 (38.4 kbps) support enables parameter setting and diagnostics. Setup file can be downloaded from the KEYENCE website.

• One‑touch calibration and auto‑tuning function accounts for target colour, brightness and surface finish to determine optimal detection method.

• The LR‑W series features a standard mounting pitch of 25.4 mm for compatibility with existing brackets.
