The pressure’s on!
P
osition sensors for hydraulics are nothing new, but these new sensors from ifm electronic are the toughest yet, and come at a great
price. The new MFH and M9H sensors are designed for operation at 500 bar, but can take peaks of 1000 bar (and have been tested to 2000 bar), because the entire construction is stainless steel, including the sensing face. They also cope well with the temperatures prevalent in hydraulics, having a maximum operating temperature of 120ºC. The high IP rating (up to IP69K) ensures that they will survive in wet conditions too. The MFH features a standard M12 thread and is available in two lengths as well as different output versions, while the M9H has an M14 thread, allowing both to be fitted to standard hydraulics. Both types connect via an industry-standard M12 connector. Using an ifm connector will guarantee performance. Besides use as a limit switch in hydraulic
cylinders, these sensors can also be used on other hydraulic components such as valves or pumps. Other high-pressure applications in mechanical engineering processes, such as in plastic injection moulding where challenging pressures and temperatures occur, are tailor-made for the MFH or M9H. The new MFH and M9H series sensors offer an impressive performance at a competitive price. ifm is committed to working closely with its customers to develop products which precisely match their needs, and the company provides expert, readily accessible technical support to help users maximise the

Technology for temperature extremes, from wenglor
I
nductive Sensors from wenglor and wenglorMEL ensure reliable detection of metallic objects in extreme temperature ranges. With three different sensor series, the product portfolio covers a comprehensive range of temperatures from -60 to +450°C. System availability is increased thanks to extended switching distances and the patented maintenance output. With a long service life of seven to ten years, the twelve rugged sensors are reliable, high performance products for use in the automotive, metalworking, food and glass industries. The INRT450 Inductive Sensor for extreme temperature ranges is the absolute worldwide forerunner where resistance to heat and cold is concerned. With a range of use from -60 to +450°C and a switching distance of 25mm, the sensor masters demanding detection tasks in extreme temperature ranges, made possible by spatial separation of the evaluation unit and

the sensor head, as well as cable lengths of 5-20 meters. The INTT25 and INTT40 models are also highly convincing where resistance to extreme temperatures is concerned. Equipped with a sensing distance of either 25 or 40mm, the new sensors are designed for hot and cold zones within a range of
-10 to +250°C. The Teflon (PTFE) sensor head withstands an ambient temperature of 250°C for an impressive 60,000 hours, and even 100,000 hours at 200°C. In particular the innovative combination of longevity and resistance to heat and cold make wenglor’s inductive sensors especially adept. www.wenglor.com
