Linear encoders

Leine & Linde’s new Linear 4000 series linear encoders are easily accessible for installation and service and provide absolute position values. The new Linear 4000 series was designed for a number of different applications. For example, steel mill’s rolling stands operate in one of the industry’s absolute toughest environments, with high temperatures, aggressive chemicals, shock impact and vibrations. The Linear 4000 can stand up against demanding environmental conditions, without the need for being mounted inside a cylinder of an operating machine. These new linear encoders come with an encapsulation which enable them to withstand heat and other strong external stresses, while their absolute inductive scanning resists the hard impact and strong vibrations. To reduce the running costs, this system doesn’t need compressed air to prevent the system against dust. As the 4000 series provides absolute position values directly to the PLC, no additional counter is required as a go-between, and the encoder cannot lose track of its position. The linear sensor in the 4000 series come with measurement lengths up to 260 mm and interfaces SSI and EnDat. Using the gateway solutions from Leine & Linde, PROFINET, PROFIBUS and EtherNet/IP interfaces are available.
