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 […]
Using LIDAR for Transmission Power Lines
Dave Brown of Terra Remote Sensing explains the use of LIDAR (Light Detection And Ranging) technology to Randy Frank at the IEEE 2011 Power Systems Conference & Expo (PSCE) held March 20-23, 2011, in Phoenix, AZ. LIDAR is being widely used by utility companies to map transmission lines for adverse conditions and vegetation. For more […]
Photoelectric and Inductive Sensors Designed for Hygienic and Washdown Apps
Hygienic applications may require more than one type of sensor. With its newest sensors, Baumer addresses measurements that require photoelectric and inductive sensing. To meet hygienic and washdown requirements, the sensors have smooth, groove-free V4A stainless steel housings. In addition, mounting accessories are EHEDG-certified, Ecolab-approved and the materials are FDA-compliant. Baumer developed its proTect+ concept […]
Infrared Detector Arrays Boast Enhanced Measurement Stability
For those applications that need to sense PbS and PbSe, Cal Sensors’ LMA (Linear Multiplexed Array) family of lead salt infrared detectors can provide up to 25% increased measurement stability. Consisting of six compensation elements and 250 active elements, the 256-element array provides real-time measurement compensation for environmental changes. Measurement corrections are made based on a comparison of the […]
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 […]
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 […]
