Keyence LV-N11CN Sensor Amplifier Supplier

Keyence LV-N11CN M8 Main Amplifier for Fast Sensor Swaps

Product Introduction
The Keyence LV-N11CN heads an LV-N series laser sensing chain as the main controller. Unlike cable-type units, it uses an M8 connector for power and signal lines. That choice pays off during maintenance, since a failed unit swaps out in seconds without re-terminating wires. The amplifier supplies two control outputs and one external input to the system. Meanwhile, its 9.8 mm body fits tight DIN rail space. Engineers typically choose this model when uptime and quick service matter more than a hardwired connection.

Technical Specifications and Performance

The LV-N11CN accepts 24 VDC nominal, with a working span of 10 to 30 VDC. Maximum consumption sits at 830 mW, about 30 mA at 24 V. Six response levels span 80 µs in HIGH SPEED through 16 ms in MEGA. This flexibility helps when targets vary in color, gloss, or distance. Output logic switches between LIGHT-ON and DARK-ON as needed. Besides that, the timer covers OFF, OFF-delay, ON-delay, and one-shot modes from 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 Outputs: 2 × NPN open collector, 30 V, 100 mA max each

• External Input: 1 input

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

Mechanical and Environmental Characteristics

A polycarbonate housing protects the electronics, sized 32.6 × 9.8 × 78.7 mm. The narrow 9.8 mm width matters when many channels share one rail. Operation holds from -20 to +55 °C without freezing, though Keyence applies derating for clustered units. Vibration tolerance reaches 10 to 55 Hz at 1.5 mm double amplitude on each axis. Shock ratings hit 500 m/s² three times per axis. Finally, humidity stays within 35 to 85 % RH without condensation.

Physical Details:

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

• Weight: Approx. 20 g (unit only)

• Case Material: Polycarbonate

• Cable Material: PVC

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

Installation and System Integration

Begin by mounting the LV-N11CN on DIN rail beside any expansion units. Slide the modules together so the expansion connector locks in place. The full chain, main unit included, must not pass 17 units, and a two-output type counts as two. Next, connect the M8 plug and confirm the supply holds above the minimum under load. Keep sensor leads short in HIGH SPEED mode to protect the 80 µs timing. For network capability, add separately available NU series communication units to the rail.

Installation Notes:

• Power off the system before connecting or removing expansion units.

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

• When more than 9 units are linked, maintain at least 20 V at the supply.

Frequently Asked Questions

Q1: How does the LV-N11CN differ from the LV-N11N?
Both are main units with two outputs and one input. The LV-N11CN uses an M8 connector, while the LV-N11N uses a fixed cable. Choose based on service speed versus hardwired simplicity.

Q2: Can this unit work without expansion amplifiers?
Yes. It runs alone as a single-channel amplifier. Expansion units simply add channels to the same system when needed.

Q3: What is the maximum chain length?
A single system supports up to 17 units including the main unit. Remember that a two-output type occupies two slots in that count.

Q4: Does the M8 connector affect response performance?
No. Response times stay the same across connector and cable types, from 80 µs HIGH SPEED to 16 ms MEGA.

Q5: How do I add network communication?
The LV-N11CN has no built-in ports. Install NU series network units on the same rail to enable fieldbus or Ethernet connectivity.
