Photoelectric Sensors Offer Application Advantages

Pepperl+Fuchs ML4.2 Series Subminiature Photoelectric Sensors have faster response times, multi-beam redundant detection, independent outputs and zero deadband sensing. The newest ML4.2 high-speed models offer 250 µs response time, half the time of the standard ML4.2 models. ML4.2 dual sensor redundant detection models have dual light beams from two emitter LEDs that reflect light to two receivers.  Compared with single beam sensing, the redundant light beam enables more reliable sensing of transparent or glossy objects that are foil or plastic-wrapped.

Multi-Pixel Array Sensors Increase Sensing Distance up to Three Times

Compared to similarly sized sensors, Pepperl+Fuchs RL31-8-H-800 multi-pixel array sensors can sense up to three times further away from the target. The sensors use an ultra high-intensity emitter called PowerBeam that provides a visible and uniform light spot, even on dark and dull black materials, to simplify sensor alignment and detection. With extremely low sensitivity to objects’ colors, the sensors can reliably and consistently detect objects and do not require re-adjustments or re-teaching if printed material changes or plastic parts fade or a new container is introduced.

Getting the Right Harsh Environment Photoelectric Sensor

Diffuse Contrast Sensor Operates within 50 µs

Print mark detection in high-speed packaging and printing operations requires a rapid response sensor.  Baumer’s FKDK 14 diffuse contrast sensor uses a white LED to precisely detect print marks within a response time of 50 µs. With the white light source, the photoelectric sensor can reliably detect print marks of all colors, even with slight contrast to the background. A yellow LED visible through the sensor’s transparent housing base indicates the switching status.

The sensor’s 14.8 x 43 x 31-mm size allows easy integration into machines.

Sensing Print Mark Detection

TRI-TRONICS MARK•EYE PRO sensor has a 45-µs response time and high immunity to ambient light. Using the broadband characteristics of a white light LED, the sensor achieves high-resolution for detecting the greatest variety of color combinations on any color background.

With the sensor’s “One-Touch” AUTOSET, setup simply involves putting the background in view, pressing the black button if the background is darker than the registration mark or pressing the white button if the background is lighter than the registration mark.

Units are available with lens and fiberoptic light guide options as well as 6-ft cable or connector options.

SICK’s W15 Photoelectric Sensors

Minneapolis, MN – SICK announces the launch of its W15 Photoelectric Sensors. These high-performance sensors use SICK’s third generation custom ASIC (application-specific integrated circuit) chip that incorporates OES3 technology to provide exceptional background suppression at an extended range. OES3 technology enables the W15 to ignore stray background reflections, detect multi-colored/shiny objects without false trips, and provide high immunity to ambient light.

The W15 provides flush mounting that reduces setup time and prevents the disruption of product flow. All W15s are assembled in the U.S. so customization options, such as cable cut to length, cable wrap with customer-specific part number, special connectivity, sensor pre-mounted to a bracket, kitted together with bracket and reflector, can help reduce material and labor costs. The W15’s advanced background suppression technology makes it ideal for a variety of applications in the packaging, material handling, and food and beverage markets.
