Pepperl+Fuchs X-Series Pile Driver™ Extended Range Inductive Sensors are now available in 8mm diameter models. With barrel lengths as short as 35mm, these miniature sensors deliver a 3mm sensing range – 50 percent more range than is available from larger competitive 12mm diameter models. As a result, 8mm diameter extended range Pile Driver sensors eliminate the need to sacrifice sensing range or durability.
Like all Pile Driver sensors, its robust, single-piece machined barrel is fully embeddable in steel making it an ideal sensing solution for the toughest metalforming and welding applications. 100% stainless steel housings deliver durability more than 20 times that of the competition’s brass and plastic housings, and Black Armor™ coated weld-immune models are available to repel even the hottest slag particles. Pig-tail connect versions feature integral high visibility power supply and target presence LEDs. X-Series Pile Driver extended range sensors are also available in 12mm, 18mm and 30mm diameters to deliver sensing ranges of 5mm, 10mm or 15mm – up to 2.5 times longer range than traditional inductive sensors. “An inductive proximity sensor's detection range is a function of its size.
Larger styles inherently offer longer sensing ranges than smaller, less powerful models. When selecting a proximity sensor, smaller versions aren't typically chosen due to their limited sensing range,” says Marcel Ulrich, Product Manager, Pepperl+Fuchs. “Instead, restricted mounting space often forces machine designers to reluctantly accommodate the limited distance. The drawback to short sensing distances is clear; a closely mounted, loose-tolerance target is more likely to impact and damage the sensor, causing downtime. Additionally, loose or irregularly-shaped targets can also generate erroneous part counts as they enter and exit the sensing field.” X-Series Pile Driver’s extended sensing field is a big benefit in automotive manufacturing applications, as it enables reliable detection of irregularly shaped contours, and increased sensor-to-target distances help eliminate contact-related scuffing of “Class A” hood, door and trunk surfaces.
Weld-immune models are uniquely capable of providing long range part detection with full immunity to both AC and DC weld fields, and repelling weld splatter. “X-Series Pile Driver’s have an up-front cost that is only 35-40% higher than a traditional plastic-faced sensor. So if a sensing application averages even one contact-related failure per year, the X-Series Pile Driver will more than pay for itself in reduced sensor replacement costs and inventory, and increased machine uptime and throughput,” says Ulrich. X-Series Pile Driver’s can detect all metals. Advanced circuitry enables restriction-free mounting while delivering the highest available immunity to the effects of industrial noise and temperature extremes. Unlike traditional inductive sensors that are limited to IP67/68 protection, X-Series Pile Driver sensors are IP69k-rated to withstand high pressure washdown cleaning.
