Pepperl + Fuchs has expanded its
ML4.2 Series of subminiature photoelectric sensors with new models offering faster response times, multibeam redundant detection, independent outputs, and zero deadband sensing. High-speed models offer 250 µs response time. Other models include dual-sensor redundant detection models, dual-sensor redundant detection and independent output models, precise sensing models, a retroreflective sensing model with no sensing deadband, and throughbeam sensors. All nonthroughbeam sensors feature integrated crosstalk immunity, 4-in-1 output, high immunity to ambient light, and diagnostic LEDs.
These sensors are perfect for applications that require more signal strength than is available with background suppression sensors, and sense at either very close or long sensing distances.
They can be used when rigid reflectors or even reflective tape must be detected up to the sensor face, as a standard retro-reflective mode sensor would typically not see reflective tape unless it were two to four inches from the sensor.
They are also well suited for detecting objects such as solar cell wafers and packaged tubes or cartons where precise and repeatable leading edge detection is a must.
As one of the Midwest's largest Pepperl & Fuchs distributors, we can help you with all of your photoelectric needs. Whether you need transparent object detection or a long-range through-beam sensor with light on/or dark on, we can help.
We can help with all of your Pepperl + Fuchs needs, just call us. With technical support on staff, we can also assist with your application questions. 800-325-9653!
A photoelectric sensor, or photoeye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter and a receiver. They are used extensively in industrial manufacturing. There are three different functional types: thru beam, retroreflective, and diffused.

Pepperl+Fuchs offers a wide range of photoelectric sensors, fiber optic cables, & accessories. They have the photoelectric sensors you need to keep your applications running. Pepperl+Fuchs, with the brand VISOLUX, is an innovator of photoelectric sensing technologies. For precise, optical control of positioning, sorting, and counting processes and for custom non-standard applications, look to Pepperl+Fuchs to have the answers for every industry.
Whether you need a
photoelectric light sensor, a linear position sensor, or are working on the latest in roller coasters and need some inclination sensors - we can help. Call us today at 800-325-9653. We have tech support on staff and are happy to discuss your application needs with you!
Pepperl+Fuchs has expanded its family of ML4.2 Series Subminiature Photoelectric Sensors. A number of new models are available to help maximize machine productivity by delivering faster response times, multibeam redundant detection, independent outputs and zero deadband sensing, among other significant benefits.
Two precise sensing models are also now available to deliver the sharpest sensing distance cut-off and smallest switching hysteresis on the market for background suppression sensors. The first model is available with a visible red emitter, and senses black and white color extremes within an extremely tight sensing window. A black test object is sensed up to 20 mm from the sensor, a white test object is sensed up to 21 mm away and no targets are detected at or beyond 22 mm. In contrast, a standard version ML4.2 sensor enables background suppression at 25 mm from the sensor. A second model senses black to 40 mm, white to 43 mm and no objects at or beyond 43 mm.
A new ML4.2 series retroreflective sensing model with no sensing deadband is used with a corner-cube reflector and is polarized so that shiny objects will not be erroneously seen as the reflector. An innovative single optical axis design eliminates sensing deadband. A second model also includes an output that monitors signal strength.
Lastly, new ML4.2 series thru-beam sensors deliver maximum signal strength in situations where retroreflective and background suppression models do not have sufficient optical power. They feature an optical alignment aid to indicate marginal signal strength, a status LED to indicate if small objects are not detected at high speeds, and quadruple the speed of previous generation thru-beam sensors. They are ideally suited for applications with sensing distances up to at least 8 meters, and in dirtier environments.

Marshall Wolf Automation, your industrial automation distributor, is your source for
Takex light curtain sensors.
Light Curtain sensors are specialized photoelectric devices that utilize two or more photoelectric beams. These sensors use through-beams (a separate sending and receiving unit) or Reflectors (a sending unit and a reflector). These units are suitable for detection of larger areas where the detection of objects ranging from the the retrieval of parts in a pick-bin to a person entering the area of a robot is non-specific and a wide area must be covered.
Takex has a wide variety of light curtain sensors available ranging from ultra-thin, cross ray, picking, and fail-safe, to name a few.
In addition to a large selection of Takex products, please visit our website at

Baumer has developed the
fastest ultrasonic sensor in the world!

The response time of the new ultrasonic sensor from Baumer is just over one millisecond. This makes the UNAM 12 ultrasonic sensor around 20 times faster than the traditional ultrasonic sensors, and the fastest sensor of its type in the world.
Marshall Wolf Automation, your full-line industrial automation distributor, is an authorized Baumer distributor.
The Baumer
UNAM 12 combines the advantages of ultrasonic technology with a short response time of 1.3 milliseconds which is the equivalent of an photoelectric sensor. The sensor is therefore perfect for use in high-speed processes and make a significant contribution to increasing efficiency in automation.
The UNAM 12 detects, for example, the presence of highly transparent packaging materials such as foils, bottles, wafers or glass, etc. controls the continuous production flow.
In order to provide maximum operational safety, the ultrasonic technology can guarantee problem-free operation of the sensor, regardless of the degree of soiling or the object color.

Baumer recently introduced a real attention-grabber for the beverage industry---SmartReflect, the

first light barrier that operates without a reflector and recognizes all types of beverage packaging, including transparent glass or plastic bottles.
Marshall Wolf Automation, your full-line industrial automation distributor, is an authorized Baumer distributor.
In Baumer SmartReflect light barriers, the light beam is closed by, for instance, a machine component. Detection takes place regardless of the color and material of the background and the relevant object. This dispenses with the separate reflectors or receivers customarily required until now.
In the beverage industry, photoelectric sensors or light barriers are most commonly used in filling and packaging applications. Especially for such operations, Baumer offers SmartReflect in a hygiene-and-washdown design with protection class IP 69K and its proTect+ leaktight concept.
Please visit our website,
www.wolfautomation.com , and view our large selection of industrial automation equipment.
In addition to being 40% smaller than previous generations and offering longer sensing ranges, the Carlo Gavazzi PA18 18mm photoelectric sensors are ideal for the following applications:
Food & BeverageThe
Carlo Gavazzi PA18 is IP69K rated for high pressure/high temperature applications. These photoelectric sensors also have ECOLAB certification for food and beverage apps.
Material Handling/ConveyorsDo you always have an issue with 18mm sensors sticking out from the mounting?
The
Carlo Gavazzi PA18 series come with a new mounting bracket (APA18-MB1) which not only allows a fast mounting but also a smooth design. Objects will not hit the sensors and the convey can be easily cleaned.
Detection of Shiny ObjectsIt can sometimes be difficult to have a retro-reflective sensor sense a can or shiny object.
Using the polarized version of the Carlo Gavazzi PA18 sensor we can eliminate reflections from the can and only light from a reflector is detected!
