• Weight: Approximately 20 g
• Case material: Polycarbonate
• Cable material: PVC
• Lifecycle status: Active; Keyence confirms production status on the official product page (last verified September 2026)

Installation Guide

• Pair the expansion unit with a main amplifier, then connect both units through the side connector.
• Mount each unit on a DIN rail or bracket, and leave space for heat dissipation in stacked setups.
• Connect the M8 connector firmly and route the cable away from motors and inverters to reduce noise.
• Wire the 24 VDC supply with correct polarity, then confirm the ripple stays within the 10% limit.
• Select LIGHT-ON or DARK-ON with the switch, and set the timer mode and value for your application.
• Keep the total expansion at 17 units or fewer, and count each 2-output unit as two.
• Verify the residual voltage at your load current, and never exceed 100 mA per output.

FAQ

• Q: What is the difference between the LV-N12CP and a main unit?
  A: This model is an expansion unit with 1 output, and it needs a main amplifier to form a working system.
• Q: What is the response time of the LV-N12CP?
  A: The fastest mode reaches 80 µs, and you can select slower modes up to 16 ms for stable readings.
• Q: Does this amplifier accept PNP or NPN sensors?
  A: The control output is PNP open collector, so plan your wiring around a PNP interface.
• Q: How many units can I connect together?
  A: You can expand to 17 units total, and each 2-output unit counts as two units.
• Q: What supply voltage does the LV-N12CP need?
  A: It runs on 24 VDC nominal and accepts 10 to 30 VDC with ripple within 10%.
• Q: Can I add network communication?
  A: Yes, the amplifier has no built-in port, but an NU series network unit adds network compatibility.
• Q: What is the operating temperature range?
  A: The unit works from -20 to +55 °C without freezing, and derating applies with multiple units.
• Q: Is the product new and in stock?
  A: Yes, we offer brand-new original units, and we hold stock for immediate order processing.
• Q: What is your return policy?
  A: We support returns within 30 days of delivery.
