Redesigned linear encoder series
Heidenhain’s redesigned LIDA 400 series linear encoder is designed for several applications including coordinating measuring machines, linear motion stages, wafer inspection, waterjet cutting, and other related applications. The redesigned LIDA 400 series is fully compatible with previous models and the scanning units are interchangeable. It features a 20-micron graduation, and has interpolation available up to 100 times from the scanning unit. The LIDA 400 exposed encoder system can have a resolution of 50 nm and accuracies to +/- 1 micron. Other features include a multi-colored status LED on the side of the scanning unit to indicate the signal levels during installation, and can be used as a quick status check of the encoder to determine functionality. The status LED also indicates the reference mark signal quality. For the digital TTL versions with interpolation, the interpolation circuits have been miniaturized to fit inside of the scanning unit housing, rather than an extended sized connector as with previous versions, which presents a cost savings advantage to the customer.
