LR-W series – Self-Contained Full-Spectrum Sensor

Detect any appearance differences (including color)

1.Innovative Technology

The unique technology in the LR-W series allows it to analyze the full light spectrum.  This series can detect everything from surface finish differences to color changes that are hard to see with the naked eye.

 

 

2.Flexibility

There are three distinct sensors in the LR-W family. With specialties ranging from general purpose, complex targets, or fiberoptic integration, this series solves problems, not just applications.

 

 

3.Lasting Detection

The LR-W’s metal housing and IP65/67 rating allow it to operate in demanding environments.  These features also mean it will last longer and require less maintenance than a conventional photoelectric sensor.

 

 

4.Unprecedented Functionality

Whether it is the 16 outputs, analog signal, or network compatibility, the MU-N series combined with the LR-W maximizes functionality unlike anything on the market.

*1 When alternate frequencies are set, the response time increases by approximately 20%.
*2 195 mA or less (at 10 V, with load)
*3 IO-Link: Specification v.1.1/COM2 (38.4 kbps) is supported. The setup file can be downloaded from KEYENCE website (http://www.keyence.com).
If you are using the product in an environment in which you cannot download files over the Internet, contact your nearest KEYENCE office.
*4 180 mA or less (at 10 V, with load)
*5 When using the IO-Link communication, if the response time is set in 1ms or more, it becomes approximately 10% slower.
*6 160 mA or less (at 10 V, with load)
*7 When the following small-diameter fiber units (the diameter of the cable is ø1.3 ø0.05″ or ø1.0 ø0.04″) are used, the IP65 rating cannot be satisfied (FU-4F/66/91/93/43/63/63T etc.). When any small-diameter fiber units except for the above are used, IP65 is applied.
*8 When the waterproof adapter A/B are not used at the time of installation of a small-diameter fiber unit, the IP65 enclosure rating cannot be satisfied.
