SENSORS Cable extension sensors have selectable outputs Variohm is offering a rugged cable extension sensor with a plastichybrid potentiometer and winding drum that can be configured for 4– 20mA or 0–10V DC outputs by connecting the appropriate signal wires during installation. The Celesco SP3 String Pot sensor provides absolute linear position measurements in four ranges from 120–1,270mm, with an accuracy of 0.25–1% of full-scale, depending on the stroke length. The sensor needs no critical cable alignment, making it suitable for awkward applications where there is insufficient space for traditional measurement devices, or where the moving components may be submerged or obscured by other equipment. The 120mm-travel version has a rated life of more than 2.5 million cycles, and repeatability is said to be better than 0.05% FS. The supply voltage is 8–40V DC for the current output version, and 12–32V DC for the voltage version. Variohm EuroSensor 01327 351004 www.variohm.com Scanning array detects web positions Sick has announced a scanning optoelectronic sensor for web-positioning and edgedetection applications. The Ax20 array sensor offers repeatable automated object detection with a resolution down to 50 microns, allowing precise control of web positions, even at high speeds. The device operates from one side of the web and has a measuring range of up to 30mm. A visible light spot makes accurate alignment easy, without needing a teach-in procedure. The sensor is said to be more versatile and reliable than fork sensors, and easier to set up. It needs no reflector, making it simple to mount. It is unaffected by ambient light and reflective or transparent materials. Applications include measuring the thickness of, and detecting the edges of, sheet-fed materials such as paper, even in stacks. It can also count small parts, determine widths, and track glue beads. Sick (UK) 01727 831121 www.sick.co.uk High-power LEDs boost sensor performance Pepperl+Fuchs has released a range of miniature photoelectric sensors for applications requiring long ranges and high reliability. The ML100 sensors use powerful lenses and PowerBeam LEDs, said to guarantee good visibility of the red light spot and easy alignment. The high power density and quality of the light spot improve the sensors’ reliability and service lives. The IP67- protected sensors have low power consumption, are insensitive to ambient lighting, and are protected against ifm has introduced inductive ring and tube sensors for detecting the passage of small metal items such as screws, rivets and springs. The high-resolution sensors have a 0.2ms response time. They can detect 0.6mm-diameter steel balls moving at up to 35m/s. For the ring sensors, the tube is guided through the ring. Because the sensing crosstalk. Indicator LEDs show the operating and switching status. There are two versions that optimise the light spot for different applications. The ML 100-8-H diffuse-mode sensors with background suppression are suitable for short ranges, providing a bright, sharp spot for simple setup and reliable detection of dark objects. The ML100-55 sensors provide a larger spot for easy alignment and longer detection ranges. Pepperl+Fuchs GB 0161 6336431 www.pepperl-fuchs.com Inductive rings and tubes detect small parts field lies inside the ring, external disturbances are minimised. The tube versions can be installed quickly and one type of sensor can be used with different diameter tubes. Pulse stretching and sensitivity are adjustable, and users can select normally open or closed operation. ifm electronic 020 8213 0000 www.ifm.com/uk
