Keyence LV-NH32 Laser Sensor Head Guide
Product Introduction
The Keyence LV-NH32 belongs to the multi-purpose digital laser sensor LV-N series. This sensor head uses a visible red semiconductor laser with a 660 nm wavelength. Firstly, it operates as a Class 1 laser product under FDA and IEC standards. The detecting distance ranges from 200 mm in HSP mode up to 1200 mm in MEGA mode. Moreover, the unit weighs approximately 65 grams and features a glass-reinforced plastic case.
Core Value
This model delivers exceptional flexibility for automated positioning tasks. The LV-NH32 provides an adjustable beam spot, which allows users to optimize the laser diameter for different target sizes. Therefore, engineers can achieve stable detection on tiny components or broader areas without changing hardware. Besides, the diffuse-reflective sensing method simplifies mounting by eliminating the need for a separate reflector. This sensor head integrates directly with LV-N series amplifiers to form a complete measurement system.
Technical Insights
The LV-NH32 supports multiple response modes through its amplifier connection. Specifically, users can select HIGH SPEED mode for fast moving targets or MEGA mode for long-range stability. The light source operates at 660 nm, which provides a clearly visible spot for alignment. Furthermore, the sensor head includes a focus ring for manual spot adjustment. This mechanical design enables precise control over the beam diameter before locking the setting with a dedicated screw. Meanwhile, the ambient temperature rating spans from -10 to +55 °C with no freezing.
Installation & Maintenance
Proper mounting is critical for achieving rated performance. Firstly, always use the included mounting bracket and tighten the screws to a maximum torque of 0.3 N·m for the LV-NH32. Over-tightening may damage the sensor housing. Secondly, adjust the spot diameter by turning the focus ring, then secure the focus lock screw to prevent drift. In addition, keep the lens cover clean using a soft cloth to avoid measurement errors. Finally, verify the amplifier settings match the selected detection distance mode after installation.
Buyer's Guide FAQ
