Heidenhain 253329-02 is an AE LS 603 scanning head intended as a replacement component for encapsulated LS 603 and LS 603C linear scales. Within the measuring system, Heidenhain 253329-02 photoelectrically scans the DIADUR graduation on the glass scale. The documented grating period is 20 µm, and the unit produces sinusoidal current signals with an amplitude of 11 µApp. Following interpolation, this signal supports submicrometre position resolution for precise movements in machine tools and measuring equipment. The scanning unit operates from a 5 V DC supply with a tolerance of ±5 %. A 15-contact Sub-D connector combines power and signal transmission. When correctly installed with the corresponding scale, the complete system reaches protection rating IP 53 for resistance to dust and splash water. Typical applications include conventional milling machines, lathes and coordinate-measuring equipment that use linear scales for axis-position feedback. The documented accuracy class is ±10 µm. Its scanning-head housing is made of aluminium, combining a low weight of approximately 0.75 kg with mechanical stability. Heidenhain 253329-02 is compatible with LS 603 and LS 603C scales across all measuring lengths, allowing the same spare-part number to be used throughout that length range. Before replacement, compare the exact ID, connector, output signal, scale type and mechanical installation with the existing measuring system.
