OMRON Releases Light Convergent Reflective Sensor "B5W-LB series"
KYOTO, Japan, Aug. 1, 2019 /Kyodo JBN - AsiaNet / --

- Realizes Stable Operation of Equipment through Precise Detection of Various 
Objects, Including Shiny, Black, and Transparent Ones -

OMRON Corporation, based in Kyoto, Japan, globally launched the Light 
Convergent Reflective Sensor "B5W-LB series" which can be embedded in 
industrial equipment. The "B5W-LB series" adopts OMRON's unique lens structure 
combining four types of aspherical lenses and realizes stable detection with a 
wide sensing range regardless of colors and materials such as shiny, black, and 
transparent surface.


Recently, advances have been made in a wide range of industrial equipment such 
as packagers and coffee makers, and they have become increasingly sophisticated 
and multifunctional. As a result, needs are growing for sensors that can 
accurately detect products without being affected by the design of containers 
and packages. Conventional reflective sensors (*1) embedded in equipment have 
been adopted on the premise that detection is carried out under specific 
conditions based on the color and material of the object to be detected. 
However, there was a problem of unstable detection when the object was changed 
or added.

By adopting the means of "detection by the light convergent reflective method" 
(*2) that has been used for sensors mainly for factory manufacturing 
facilities, "B5W-LB series" sensors are not affected by a change of object 
color and/or material, contributing to a reduction of malfunctions. On the 
other hand, sensors using the light convergent reflective method have a 
narrower range of distance for detecting an object, and may overlook a product 
that is not in its predetermined position. The "B5W-LB series" sensors adopted 
OMRON's unique lens structure combining four types of aspheric lenses, ensuring 
a wider detection range and allowing stable detection even if product positions 

OMRON will continue to actively promote research and development to realize 
automation of various applications with sensors, contributing to solving 
customers' problems.

Major Applications:

Main Features
- Stable detection of mirror, black, and transparent objects. No need for a 
setting change for each object to be detected, contributing to higher usability.
- Reliable detection of an object regardless of its color and/or background, 
reducing malfunction and contributing to customer satisfaction.
- OMRON's proprietary lens structure combining four types of aspheric lenses 
ensures a wide detection range which is less susceptible to an object's 
positional shift, and contributes to stable operation of equipment.


Release date
Japan: June 2019
Global: July 2019

(*1) A sensor that detects the presence or absence of an object by emitting 
light to the object and receiving the reflected light

(*2) Principle of light convergent reflective sensor
The sensor receives light reflected from an object to be detected for detection 
of the presence of the object. It has an optical system that limits the 
emitting beam and the light-receiving area, and detects only an object at a 
certain distance from itself (the overlapping area of the emitting beam and the 
light-receiving area).
