Hold down the button while targets are moving past the sensor beam.
You can apply logic delays to the output signal to accommodate slower PLC scan times. No timer delay applied.
: While newer models exist, the LV-N11N remains a "gold standard" for its reliability in humid or vibrating environments, leading to its continued high demand on the secondary market. LV-N11N Market Availability keyence lv n11n user manual pdf verified
The LV-N11N features several calibration methods via its "SET" button. Below are the two most common methods verified for optimal stability. Two-Point Calibration (Standard Object Detection)
The LV-N11N utilizes NPN output. The wiring includes a power supply ( ) and control output lines. +Vpositive cap V Blue: Black: Output 1 (NPN) White: Output 2 (NPN - optional) 3. Connecting Sensor Heads Open the connector cover on the side of the main unit. Insert the sensor head cable connector until it clicks.

When it comes to industrial automation, few components are as critical as the sensor. The is a flagship model in Keyence’s LV-N series of digital laser sensors, renowned for its high-performance, long-distance sensing capabilities. However, owning this powerful device is only half the battle. To truly harness its potential—from adjusting gain settings to troubleshooting output errors—you need the official documentation.
You can access verified technical manuals and data sheets through these authoritative sources: : While newer models exist, the LV-N11N remains
Press "SET" once with the target present and once without. This is ideal for detecting small differences in distance or reflectivity.
While this guide covers over 90% of daily operations, highly specialized setups (such as setting up the zero-shift function, configuring cross-talk prevention for multiple side-by-side units, or using the analog output window) may require the official schematic diagrams from the manufacturer.
The manual clarified it instantly. The grey wire was the . In his haste during the last repair, a junior technician had taped it off, assuming it was a spare. The manual, however, explained that leaving it floating could cause erratic behavior in certain "Gate" timing modes. He stripped the wire and grounded it correctly. The unit powered up with a solid green light.
