Keyence LV-N10 Expansion Unit Supplier

Keyence LV-N10 Expansion Amplifier for Precision Laser Sensing

Product Introduction
The Keyence LV-N10 serves as a dedicated expansion unit within the LV-N series ecosystem. It enables users to build multi-channel laser sensing systems without duplicating the main controller. This module is specifically a zero-line type, meaning it lacks built-in control outputs or external inputs. Consequently, it must be paired with a compatible main amplifier unit to function. The compact form factor allows for tight DIN rail mounting in control cabinets. Its primary role is to add sensing channels to an existing setup, providing scalability for complex inspection or positioning tasks.

Technical Specifications and Performance

The LV-N10 operates on a nominal 24 VDC supply, with an allowable range of 10 to 30 VDC. Power consumption is efficient, rated at a maximum of 830 mW under normal conditions at 30 V. Users can select response times ranging from 80 µs in HIGH SPEED mode to 16 ms in MEGA mode, balancing speed and stability for different target materials. The output selection is switch-configurable between LIGHT-ON and DARK-ON operating modes. Furthermore, the built-in timer function supports OFF-delay, ON-delay, and one-shot operations with a setting range of 1 ms to 9,999 ms.

Key Electrical Parameters:

• Supply Voltage: 24 VDC nominal (10–30 VDC operating)

• Response Time: 80 µs (HIGH SPEED) / 250 µs / 500 µs / 1 ms / 4 ms / 16 ms

• Control Output: NPN open collector 30 V, 100 mA max (stand-alone)

• Timer Range: 1 ms to 9,999 ms (selectable)

Mechanical and Environmental Characteristics

Designed for industrial durability, the LV-N10 features a polycarbonate housing that measures just 9.8 mm in width. This slim profile is critical for high-density panel layouts. The unit is rated for operation in temperatures ranging from -20 to +55 °C without freezing. It also withstands vibration (10 to 55 Hz, 1.5 mm amplitude) and shock (500 m/s²). When installing multiple units, thermal derating may apply; therefore, adequate ventilation or spacing is recommended in enclosures.

Physical Details:

• Dimensions: 32.6 mm (H) × 9.8 mm (W) × 78.7 mm (D)

• Weight: Approx. 20 g (bare unit)

• Case Material: Polycarbonate

• Protection Circuit: Reverse polarity, over-current, and surge absorber

Installation and System Integration

Integrating the LV-N10 into an existing system requires careful attention to the expansion bus. First, mount the unit onto a DIN rail alongside the main amplifier. Next, slide the units together to engage the expansion connector. The total number of connected units, including the main unit, must not exceed 17 (with a two-output type counted as two units). Power wiring should be daisy-chained or distributed appropriately, ensuring the supply voltage stays above the minimum threshold when several units are linked. For network connectivity, this amplifier can be combined with NU series communication units to enable fieldbus integration.

Installation Notes:

• Always power off the system before connecting or disconnecting expansion units.

• Use a Class 2 or LPS power supply to meet safety standards.

• When connecting more than 9 units, ensure the supply voltage is at least 20 V.

Frequently Asked Questions

Q1: Does the LV-N10 work as a standalone sensor?
No, this is an expansion unit. It lacks main control outputs and requires a main amplifier (such as the LV-N11N) to function and provide output signals.

Q2: What is the maximum number of units I can connect?
You can connect up to 17 units in total, including the main unit. Please note that a two-output type amplifier counts as two units toward this limit.

Q3: Can I adjust the response speed on this expansion unit?
Yes. The response time is selectable via the main unit or software, offering speeds from 80 µs (HIGH SPEED) up to 16 ms (MEGA) depending on the connected sensor head and cable length.

Q4: What is the function of the timer on the LV-N10?
The built-in timer allows for delayed or extended output signals. Options include OFF-delay, ON-delay, and one-shot, with adjustable duration from 1 ms to 9,999 ms.

Q5: Is the LV-N10 compatible with network communication?
Directly, no. However, it can be integrated into a network by using separately available NU series communication units, which mount alongside the LV-N series amplifiers.
