Keyence LV-NH64 Retro-Reflective Sensor Head

Product Introduction

The Keyence LV-NH64 belongs to the LV-N series of digital laser sensor heads. It uses a retro-reflective area-type design with a magnified beam. This configuration suits long-distance area detection where a reflector sits opposite the sensor.

Engineers select the LV-NH64 when they need broad coverage across a wide span. The magnified beam spreads light across a larger zone than a small-spot head. Therefore, the sensor detects targets that shift position within the sensing area.

Technical Specifications

The LV-NH64 sensor head delivers reliable optical performance for long-range area sensing. Its core parameters appear below for quick reference.

• Light Source: Visible red semiconductor laser, 660 nm

• Laser Class: Class 1 (FDA CDRH Part 1040.10, IEC 60825-1)

• Detecting Distance: 800 to 1300 mm in MEGA mode (1000 to 1700 mm optional)

• Category: Retro-reflective, area type

• Type: Magnified beam, long-distance area

The sensor head contains no built-in ports or communication protocols. Instead, it connects to an LV-N amplifier unit through a dedicated cable. Therefore, output type and power consumption depend on the paired amplifier.

Mechanical and Environmental Parameters

The housing uses glass reinforced plastic for durability in factory settings. Meanwhile, the unit weighs approximately 70 g, which keeps mounting stress low on brackets.

Operating temperature: -10 to +55 °C, no freezing
Relative humidity: 35 to 85 % RH, no condensation
Case material: Glass reinforced plastic
Weight: Approx. 70 g

The protection rating is not specified in available data. Besides, dimensions are not published for this model. For instance, confirm mounting clearance with your Keyence representative before installation.

Installation Guide

First, mount the LV-NH64 on a rigid bracket facing the reflector. Next, connect the dedicated cable to a compatible LV-N amplifier unit. After that, power the amplifier and align the magnified beam with the reflector.

The visible red laser helps operators align the area beam during setup. Specifically, adjust the head angle until the beam covers the full target zone. Furthermore, keep both the lens and reflector clean to maintain stable detection over long distances.

Finally, verify the sensing response within the 800 to 1300 mm window. However, avoid strong ambient light near the beam path. Therefore, shield the sensor from intense reflections when possible.
