Product Introduction
The Keyence LV-NH37 belongs to the LV-N series of digital laser sensor heads. It uses a diffuse-reflective spot-type design with an ultra-small beam spot. This configuration suits micro-component detection and high-precision positioning tasks.
Engineers select the LV-NH37 when they need to detect tiny targets at short range. The ultra-small spot concentrates laser energy on a narrow area. Therefore, the sensor can distinguish small features that a standard beam would miss.
Technical Specifications
The LV-NH37 sensor head delivers precise optical performance for micro-target 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: 70 ±15 mm in MEGA mode
Category: Diffuse-reflective, spot type
Type: Ultra-small beam 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 small fixtures.
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-NH37 on a rigid bracket at the required working distance. Next, connect the dedicated cable to a compatible LV-N amplifier unit. After that, power the amplifier and confirm the spot position on the target.
The visible red laser helps operators align the ultra-small beam during setup. Specifically, position the beam center on the feature to be detected. Furthermore, keep the lens clean to maintain stable detection at close range.
Finally, verify the sensing response within the 70 ±15 mm window. However, avoid strong ambient light near the target area. Therefore, shield the sensor from intense reflections when possible.
