Keyence LV-NH62 Retro-Reflective Sensor Head

Product Introduction

The Keyence LV-NH62 belongs to the LV-N series of digital laser sensor heads. It uses a retro-reflective spot-type design with a standard small spot. This configuration suits long-distance detection where a reflector sits opposite the sensor.

Engineers choose the LV-NH62 when they need reliable sensing across a wide span. The retro-reflective method uses a reflector to return the beam to the receiver. Therefore, the sensor achieves an 8 m range while keeping the wiring on one side only.

Technical Specifications

The LV-NH62 sensor head delivers reliable optical performance for long-range retro-reflective 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: 8 m maximum in MEGA mode

• Category: Retro-reflective, spot type

• Type: Standard (small spot)

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 65 g, which reduces mounting stress on brackets.

Operating temperature: -10 to +55 °C
Relative humidity: 35 to 85 % RH, no condensation
Case material: Glass reinforced plastic
Weight: Approx. 65 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-NH62 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 beam with the reflector center.

The visible red laser helps operators align the small spot during setup. Specifically, adjust the head angle until the returned beam reaches the receiver. Furthermore, keep both the lens and reflector clean to maintain stable detection over long distances.

Finally, verify the sensing response at up to 8 m in MEGA mode. However, avoid strong ambient light near the beam path. Therefore, shield the sensor from intense reflections when possible.
