SENPUM – LA-N Series

Digital Long-range (Amplifier+Sensor head)

Brand : SENPUM

The SENPUM LA-N Series is a family of high-precision digital laser sensors designed for accurate distance detection and object sensing in industrial automation applications. These sensors use a visible red laser light source with a stable beam profile, enabling long-range detection with minimal degradation through small gaps or off-axis variations, which helps overcome installation limitations. The digital design supports multiple sensing range modes, making the LA-N Series adaptable to diverse use cases such as presence detection, position verification, and contrast sensing.

Featuring compact sensor heads with configurable detection modes (e.g., SUPER, ULTRA, MEGA) and support for external amplifiers with multi-output control, the LA-N Series gives users flexibility in integrating with PLCs and control systems. With built-in protection against environmental interference, robust industrial construction, and optional reflective boards and tapes for improved target detection, these sensors deliver reliable operation in demanding environments.
