LS101-D100ND Photoelectric Sensor

Ultra-small specifications

The sensor is only the size of a fingertip. Therefore, its ultra-small and ultra-thin design makes it suitable for installation in various narrow spaces.

Sensitivity adjuster in ultra-compact size

Despite its small size, the sensor has a built-in sensitivity adjuster. As a result, users can conveniently fine-tune the sensitivity when required.

Long-distance detection

Despite its small size, the LS series can still detect objects over long distances. Therefore, it can also work well on wide conveyors.

High detection accuracy

The sensor can accurately detect small objects. In addition, it provides high detection accuracy for reliable object detection.

Outlet method

The sensor comes with a two-meter bend-resistant cable. This design provides a convenient outlet method for installation.
