KEYENCE LV-NH32 Adjustable Beam Spot Reflective Laser Sensor Head

The KEYENCE LV-NH32 is a spot reflective laser sensor head designed for the LV-N series of digital laser sensors. Its ability to adjust the beam spot diameter enables flexible detection of both minute targets and larger objects across a wide range of distances. Class 1 visible red laser, 660 nm wavelength. Glass‑reinforced plastic housing, IP67 rating, –10 °C to +55 °C.

Applications:

• Semiconductor and electronic component detection (small parts, fragile wafers)

• Automotive parts manufacturing and assembly verification

• Packaging machinery for label registration and web control

• General parts presence and positioning in industrial automation
