Performance and Environmental Durability

• The LV-N12CN offers six selectable response modes, so users can balance speed and stability.
• HIGH SPEED mode reaches 80 µs for high-throughput detection tasks.
• MEGA mode at 16 ms suits slow-moving targets and noisy environments.
• The amplifier tolerates -20 to +55 °C and 35 to 85 % RH without condensation.
• Vibration and shock ratings support reliable use on moving machinery and production equipment.
• Interference prevention limits cross-talk between 0 and 4 units, depending on mode and head.
• Reverse polarity, over-current, and surge absorber circuits protect the amplifier during wiring faults.

Installation Guide

• Mount the unit on a DIN rail or panel with the 32.6 × 9.8 × 78.7 mm housing.
• Connect the M8 connector firmly and confirm the pin assignment before power-on.
• Wire the 24 VDC supply within the 10 to 30 VDC operating range.
• Select LIGHT-ON or DARK-ON with the switch to match your detection logic.
• Set the timer from 1 ms to 9,999 ms when your process needs delay or one-shot output.
• Chain expansion units up to 17 total units and check interference prevention settings.
• Keep multiple units within the derating limits for ambient temperature.
