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.

Color Sensors Use Alternative Approach

Instead of using colorimetric level to identify colors, MAZeT’s JENCOLOR color sensors use the radiometric level. The MMCS6 sensor family makes a color measurement with seven spectral characteristics in the range of 380 to 780 nm based on spectral estimation. This data is used to calculate the chromaticity coordinate. This provides a much higher information density in terms of color measurement. The multiple color sensor technology bridges the gap between the three-range sensors with their inherent limitations and spectral measurement devices for sensor applications.

Robotic Floor Cleaner Relies on Sensors

At the Digital Experience at the 2011 International CES in Las Vegas, Evolution Robotics displayed a robotic hardwood floor cleaner that used several different types of sensing technologies. For navigation, the robot uses a NorthStar navigation system that provides a GPS-like beacon using infrared technology to the robot to guide the robot’s path across the floor. Stephan West of Mint explained this and the other sensing capabilities of the robotic floor cleaner to Randy Frank.

Single IR-Based Sensor Performs Ambient Light and Proximity Sensing

At Convergence 2010 in Detroit, Intersil’s Niyant Patel explains how a single infrared (IR) sensor can provide both ambient light and proximity sensing for vehicles. The Intersil ISL29028 ambient light and proximity sensor operates linearly down to 1 millilux and can use 850nm and 950nm external IR LEDs.

The Object of Pepperl+Fuchs Newest Photoelectric Sensors is Clear

That is clear object detection. GLV18 Series photoelectric sensors with Clear Object Detection use reflectors to detect transparent objects up to 2.5 m away, or opaque objects up to 5 m away.

Offered in an industry-standard M18 threaded cylindrical housing, the sensor is up to 50% shorter. In addition, the company claims the power consumption is 50% less than many competitive models. 

The sensors can detect clear shrink-wrap webs or semi-transparent trays or cartons in material handling applications as well as the presence detection of clear clamshells, bottles, or pouch webstock in packaging applications.

Photoelectric Sensor Includes Suppression Sensors

Users looking to standardize on a mid-sized block style photoelectric sensor need to search no further than the BOS 23K sensor family from Balluff. Featuring the conventional sensing modes of diffuse, retro-reflective, and thru-beam, the BOS 23K also includes background suppression sensors, thus making it suitable as a “go-to” family for all of your sensing needs.

• Long sensing ranges for extended sensing ability
• Accurate switching performance for precise positioning tasks
• Highly visible red light for easy alignment
• At-a-glance status indication LEDs, viewable from all sides
• Two mounting options – holes or dovetail – for flexible sensor placement
• Impact-resistant ABS housing with rotating connector suitable for many applications

Ideal for use in material handling and conveying applications, the BOS 23K photoelectric block sensor provides a great combination of high accuracy and long sensing range at a reasonable price. In a typical application for example, two BOS 23K diffuse sensors with background suppression are able to monitor different colored totes as they travel from one production station to another without false triggering on the background.
