Product Introduction
The Keyence LV-NH47 belongs to the LV-N series of digital laser sensor heads. It uses a diffuse-reflective area-type design with definite-reflective characteristics. This configuration suits stable detection of targets at a fixed working distance.
Engineers select the LV-NH47 when they need consistent sensing across a defined range. The definite-reflective behavior reduces false triggers from background objects. Therefore, the sensor performs well in applications with reflective surfaces nearby.
Technical Specifications
The LV-NH47 sensor head delivers reliable optical performance for fixed-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: 55 to 85 mm in MEGA mode
Category: Diffuse-reflective, area type
Type: Definite-reflective
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
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-NH47 on a rigid bracket at the target working distance. 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 position until the beam covers the target zone evenly. Furthermore, keep the lens clean to maintain stable detection at short range.
Finally, verify the sensing response within the 55 to 85 mm window. However, avoid strong ambient light near the target area. Therefore, shield the sensor from intense reflections when possible.
