The Keyence LV-NH67 belongs to the LV-N series of digital laser sensors. Specifically, this unit serves as a retro-reflective spot-type sensor head designed for long-distance applications. Its narrow spot beam travels far and returns from a reflector, which makes it ideal for large conveyors and wide production lines. Additionally, the visible red laser spot simplifies optical alignment over extended distances. Therefore, technicians can position the head and reflector accurately without special tools. The head contains no output circuitry. Instead, it relies on a dedicated cable connection to an LV-N series amplifier for power and signal processing.
The optical performance of the LV-NH67 centers on a 660 nm visible red semiconductor laser. This light source meets Class 1 laser safety requirements under FDA CDRH Part 1040.10 and IEC 60825-1 standards. Consequently, the sensor operates safely in typical industrial environments without additional protective enclosures.
The detecting distance depends on the response mode selected on the connected amplifier. In MEGA mode, the LV-NH67 achieves a range of up to 30 m using the included reflector. Furthermore, when paired with the optional OP-42198 reflector, this range extends to 50 m. Other modes provide shorter but faster detection: ULTRA, SUPER, TURBO, FINE, and HSP. Next, users should select the mode that balances speed and range for their specific application.
This sensor head contains no built-in communication ports or output transistors. Instead, all signal processing occurs within the LV-N series amplifier. Therefore, the LV-NH67 requires a compatible amplifier unit (such as LV-N11N or LV-N12N) to function. The amplifier supplies power and converts the optical signal into a usable NPN or PNP output.
The LV-NH67 housing uses glass-reinforced plastic for the main case. This material provides dimensional stability across the operating temperature range of -10 to +55 °C (no freezing). Moreover, the sensor tolerates relative humidity from 35 to 85 % RH without condensation.

First, secure the LV-NH67 using the included mounting bracket. The tightening torque for the bracket screws should not exceed 0.3 N·m. Over-tightening may damage the plastic housing. Next, position the reflector directly opposite the sensor head. The spot beam requires careful alignment, but the long range allows flexible placement of both units.
Open the dust cover on the amplifier and lower the hold lock lever. Then, insert the sensor head connector fully into the amplifier port. Finally, raise the hook and secure the lock lever before closing the dust cover. After connection, verify that the amplifier recognizes the LV-NH67 head. If the display shows an unexpected model code, initialize the amplifier settings and reconnect the head.
Power on the amplifier and set the response mode to MEGA for maximum range. Align the sensor head so the red laser spot strikes the center of the reflector. Meanwhile, observe the amplifier's incident light intensity indicator. Adjust the head angle until the intensity reaches its maximum. For small targets, consider switching to FINE or HSP mode to improve detection stability.

Q1: Does the LV-NH67 work without an amplifier?
A: No. The LV-NH67 is a sensor head only. It requires an LV-N series amplifier unit for power and signal output. Without an amplifier, the head cannot operate or produce a detection signal.
Q2: What is the maximum detecting distance of this model?
A: In MEGA mode with the standard included reflector, the range reaches 30 m. When using the optional OP-42198 reflector, the maximum distance extends to 50 m.
Q3: What is the difference between LV-NH67 and area-type heads?
A: The LV-NH67 projects a narrow spot beam rather than a wide area beam. This design concentrates laser energy for long-distance detection, while area-type heads spread the beam for close-range coverage.
Q4: Can I use the LV-NH67 for outdoor applications?
A: The LV-NH67 is designed for indoor industrial use. Direct sunlight may interfere with the laser beam. Therefore, use shielding or indoor mounting whenever possible.
Q5: How should I clean the sensor lens?
A: Gently wipe the lens cover with a soft, dry cloth. Avoid solvents or abrasive materials. Since the case is plastic, harsh chemicals may cause clouding and reduce optical performance.
