Self-contained full spectrum sensor

Keyence has developed the LR-W line of photoelectric sensors, designed for missing objects check, assembly components control, product differentiation and more.

These devices deliver consistent, unparalleled detection of any changes to appearance or color, easily bolstering the simplest applications and the most complex ones.
Compared to conventional sensors that use a red LED, the LR-W series employs a white LED and the full light spectrum, making it possible to make out a much broader range of products (objects with slight variations in color, metallic objects, sloped, black, etc.).

The system has an automatic brightness adjustment function that optimizes the sensor’s power and sensitivity, guaranteeing excellent performance even with white targets, and boasts an impressive 500 mm range of detection, enabling it to manage applications previously considered out of range.
Easy to use and with a long useful life, the LR-W series is equipped with a display featuring seven segments, prominently positioned and supplying continuous feedback, as well as indicators of detection mode and stability.
It is easy to calibrate, with three different calibrations, including the innovative “master” calibration requiring just the push of a button. A robust metal housing enables use on any machine type under any conditions.
