A scanning head reads a steel scale tape with absolute and incremental METALLUR tracks. The safety-related configuration includes functional safety and a failsafe mechanical connection; the head, scale, mounting and downstream electronics must be selected and installed as a matched system.\u003c\/p\u003e\n\u003ch2\u003eTechnical Data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety-related configuration:\u003c\/strong\u003e LIC 4119 with LIC 4009 scale tape and an FS scanning head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring standard:\u003c\/strong\u003e steel scale tape, adhesively bonded to an aluminum or steel mounting surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterface:\u003c\/strong\u003e EnDat 2.2, ordering designation EnDat22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasuring steps:\u003c\/strong\u003e 10 nm, 5 nm or 1 nm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy grades:\u003c\/strong\u003e ±3 µm up to 1020 mm; ±15 µm, with ±5 µm possible after linear-error compensation in the downstream electronics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTypical baseline error:\u003c\/strong\u003e no more than ±0.750 µm per 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterpolation error:\u003c\/strong\u003e ±20 nm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTraversing speed:\u003c\/strong\u003e up to 600 m\/min, subject to interface and system conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply voltage:\u003c\/strong\u003e 3.6 V to 14 V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTypical current:\u003c\/strong\u003e 75 mA at 5 V without load\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1 m or 3 m cable with an 8-pin M12 coupling or 15-pin D-sub connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum cable length:\u003c\/strong\u003e 100 m with the specified cable and clock frequency no higher than 8 MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScanning-head operating temperature:\u003c\/strong\u003e -10 °C to 70 °C; scale length limits depend on operating temperature and mounting surface\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelative humidity:\u003c\/strong\u003e up to 93% under the stated test conditions, with condensation excluded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScanning-head mass:\u003c\/strong\u003e up to 18 g without cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFunctional safety and selection\u003c\/h2\u003e\n\u003cp\u003eThe specified FS configuration is intended for applications up to SIL 2 under EN 61508 and Category 3, PL d under EN ISO 13849-1:2015. These are application limits, not a guarantee that an assembled machine meets them. The specified encoder safe position is ±550 µm, with a safety-relevant measuring step of 220 µm. These safety values are separate from the normal 1 nm measuring step.\u003c\/p\u003e\n\u003cp\u003eFault exclusions for loosening of the head and scale depend on the specified mechanical installation. Confirm the exact FS head and scale IDs, measuring length, mounting surface, temperature range, connection and downstream safety requirements before selecting a replacement. A standard non-FS LIC 4100 part is not automatically interchangeable with an FS configuration.\u003c\/p\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/docs.auto-met.com\/1-HEIDENHAIN-Exposed-Linear-Encoders-2025.pdf\" target=\"_blank\" rel=\"noopener\"\u003eExposed linear encoder catalog, February 2025, including LIC 4100 functional safety and specifications (PDF)\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eMachine down?
