Des Plaines, IL -Parker Hannifin's new 2MA pneumatic cylinder with linear position sensor accurately senses a piston's position in relation to its stroke to the nearest one-thousandth of an inch. "We use a new magnetostrictive transducer for providing feedback to a PLC or digital readout that indicates the piston position," says Fiona Abrams, a Parker-Hannifin design engineer responsible for the product. "The sensor is mounted externally, so there are not a lot of retrofit issues."
With this new magnetostrictive technology, no re-homing of the device is necessary. In addition, the transducer compensates for differences in magnetic fields with automatic tuning.
The company uses standard cylinders from their product line and adds the electronics on top. Externally mounting electronics eliminates drilling through the rod and special end covers. "There is nothing else like it out there," says Mary Morris, engineering manager at the company's pneumatic business unit.
"The 2MA is suitable for use with clevis mounts, head or cap trunions, extended tie-rods, or side or angle mounts," says Abrams. Its typical pneumatic applications are in automotive, material handling, packaging, and mobile equipment industries. Bore sizes range from two to eight inches.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
