Claiming the first photoelectric light barrier to operate without a separate reflector or receiver, Baumer’s SmartReflect light barriers have several features. The devices create a closed light beam between the sensor and any background for reliable detection of target objects regardless of color, shape, transparency or surface texture. Substitution of any machine part in the […]

Robot Provides Virtual Presence at 2012 CES (Pt 2)
At the 2012 International CES (Consumer Electronics Show) in Las Vegas, Alexandra Dopplinger, a marketing manager at Freescale Semiconductor explains the capability of a remote robot that she controls from her location in Ottawa, Canada. Freescale’s pressure sensors and accelerometers are used in the design of the robot as well as proximity sensors to detect […]
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 […]
Measuring with a 2D Optical Micrometer
Keyence calls its TM-3000 the world’s first in-line 2D optical micrometer. By combining the functionality of a laser scan micrometer, machine vision system and optical comparator into a single device, the sensor eliminates the need for expensive positioning mechanisms to ensure the best precision. The 2D optical micrometer has a dual telecentric lens and a two-dimensional […]
Make Non-Contact Precision Displacement and Thickness Measurements
In a manufacturing environment, non-contact measurements are especially useful for moving processes, hot parts, machined parts and soft or sticky parts. Banner Engineering addresses these kinds of applications with the L-GAGE LH Series Non-Contact Laser Sensor. Developed to solve measurement and quality control inspections on materials such as wood, metal, rubber, ceramic and plastic parts, […]
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 […]
Getting the Right Harsh Environment Photoelectric Sensor
Photoelectric Sensor Targets Harsh Environments
Banner Engineering Corp. repackaged its TM18 EZ-BEAM photoelectric sensor for use in heavy duty environments. With its nickel-plated, die-cast zinc metal housing and completely epoxy encapsulated electronics, the TM18 achieves an IP69K rating. This design provides the durability and resistance for harsh industrial sensing environments, such as those with high pressure washdowns. For easy alignment […]
ROHM Semiconductor’s Sensors Race Track
At Sensors Expo 2011, Steve Chutka, a field applications engineer at ROHM Semiconductor USA explains the sensors on its small demo truck to Sensor Tips’ Randy Frank. The six sensors communicate to a sensor hub via ZigBee wireless protocol. For more information about ROHM Semiconductor’s sensors and other products, click here. To watch the video, […]
Vision Sensor Reads Linear and Data Matrix Codes
With its Sharpshooter ID vision sensor, Balluff now has an ID version designed to read a large range of linear bar codes and 2D Data Matrix codes, as well as optical character verification (OCV). The vision sensor can read more than 10 types of linear bar codes, including PDF417 and 2D Data Matrix codes. The […]
