Keyence LV-NH42 Laser Sensor Head Area Type

Product Introduction

The Keyence LV-NH42 belongs to the LV-N series of digital laser sensor heads. It uses a diffuse-reflective area-type design for long-distance detection. This configuration suits presence checks and wide-target sensing on production lines.

Engineers choose the LV-NH42 when they need to cover a broad detection area at extended range. The area-type beam spreads light across a wider zone than a spot type. Therefore, the sensor can detect targets that shift position within the field.

Technical Specifications

The LV-NH42 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: 1200 mm maximum in MEGA mode

• Category: Diffuse-reflective, area type

• Type: Long-distance

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-NH42 on a rigid bracket aimed at the target zone. Next, connect the dedicated cable to a compatible LV-N amplifier unit. After that, power the amplifier and check the beam coverage on the detection area.

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 the lens clean to maintain stable detection over long distances.

Finally, verify the sensing response at up to 1200 mm in MEGA mode. However, avoid strong ambient light near the target area. Therefore, shield the sensor from intense reflections when possible.
