Multi-Purpose Digital Laser Sensor

LV-N series

LV-NH42 Area Beam Reflective

Small size and highly flexible installation

Detecting irregular shaped targets is not a problem with the LV-NH42 laser sensor head

LV-NH42 Long Distance, Wide-area Detection Laser Sensor

With this powerful, long distance, wide-area detection sensor, once difficult and expensive problems can now be solved easily and at lower cost. Even with a varying target shape the LV-NH42 enables stable detection in most applications.

Area Spot for More Reliable Detection

With conventional sensors, the detection area can be out of focus when the sensor is further away from the target, or if the detection area is limited when using a small spot. The LV-NH42 solves both of these problems. Even when the sensor is a long way from the target, the sensor produces a clear linear spot. This results in reliable detection even if there is variation in the position and shape of targets.

Clear linear spot results in reliable long range detection even with irregular shaped targets

Semiconductor laser sensor is a compact size

The Ultra-compact Sensor Head can be Mounted Almost Anywhere

The size of the LV Series sensor head is half the size of our conventional sensor heads even though it is a reflective type that uses a semiconductor laser.

Detection stability level indicator included as a standard feature

The Sensor Head is Equipped with a "Level Indicator" that Indicates the Detection Stability

A "level indicator" is a standard feature on all KEYENCE laser sensors and indicates the detection stability. The operation status and detection stability can be easily checked without viewing the indicator on the amplifier.

A Semiconductor Laser is used as the Light Source.

By using a semiconductor laser as a light source it allows the LV series to form a sharp beam spot even at a long distance.

Even when mounted away from the target, the LV series can accurately detect and differentiate that which would have been impossible with a sensor using a LED as a light source.

Applications

KEYENCE LV Series

KEYENCE LV Series

Confirmation of the Presence of a Suspension System

Using a wide beam spot ensures stable and reliable detection even when the target path slightly deviates.

Detection of Filaments

A filament is detected through a glass window. Although a thrubeam type sensor can be used, the setting is difficult. The bright beam spot of the reflective type laser sensor allows for easy set up.
