LM13 Incremental Magnetic Encoder UNIQUE REFERENCE MARK SMALL SIZE AND SIMPLE INTEGRATION The LM13 is a high-speed, non-contact magnetic rotary encoder system designed for linear or rotary motion in harsh environments. If features a compact readhead and a self-adhesive magnetic scale or ring. Simple to install, the LM13 features a set-up LED and large mounting tolerances. The encoder is available with digital or analogue output variants and offers a range of customer-selectable resolutions from 0.244 μm to 250 μm or from 25 dpi to 25,600 dpi for printing applications. WEAR-FREE MEASURING PRINCIPLE Customer selectable resolutions High speed operation Excellent dirt immunity to IP68 Linear or rotary position sensing COMPACT SIZE ASSEMBLY LINES LINEAR MOTOR Non-contact and wear-free measuring principle Unique bidirectional reference mark CE compliant, including RoHS PRINTING TECHNOLOGY

General information Engineered for extreme service, the solid-state LM13 linear encoders operate from –10 °C to +80 °C, have water-proof sealing to IP68 and are highly resistant to shock, vibration and pressure. The robust magnetic scale and ring are also resistant to various of chemicals commonly found in industry. The non-contact, frictionless design eliminates wear and reduces hysteresis. Choose your LM13 system The robust LM13 readhead is compatible with the RLS MS10 incremental scale as well as the RLS axial and radial rings. You can select the length of the MS scale up to 150 m. There...

Storage and handling All data given below refer to the readhead only. Complete systems with magnetic scale or ring may have other limitations. For more information, see the MSD01, MR01D01 or MR02D02 data sheet at RLS Media center. Storage temperature Operating temperature Readhead is ESD sensitive - handle with care. Do not touch electronic circuit, wires or sensor area without proper ESD protection or outside of ESD controlled environment. This encoder system is a high performance metrology product and must be handled carefully. The use of industrial tools during installation or exposure...

Label on the readhead contains: full PN, 6 digits long serial number and 2D code containing the serial number. Dimensions Dimensions and tolerances are in mm. Dimensions without tolerance values are in accordance with ISO 2768-m. Reference sensor side 3D model available for download at RLS Media center. General tolerances for linear dimensions according to ISO 2768 m Tolerance class

Installation instructions Fasteners M2,5 The readhead LED must be green at all measuring length positions. Otherwise, the installation is not performed correctly. The (not provided) 0.1 mm to 1.0 mm thick plastic spacer (shim) can be used to facilitate installation. For optimal installation, the recommended thickness of the shim is 0.3 mm. After mounting the magnetic scale, place the plastic shim and the readhead on the magnetic scale. Make sure that the readhead, shim and magnetic scale are in full contact. Installation surfaces Improper mounting of the magnetic scale and readhead can...

Response time Set-up time Interpolation conversion time Transition time Set-up time is the time needed for the encoder readhead to start reading the position information after power-on (see diagram 1). Interpolation conversion time is the time needed for the encoder readhead to convert the position information into an output signal. Transition time is the time it takes the encoder readhead to switch from an alarm state to a valid output signal (see diagram 2). Diagram 1: Set-up time Power supply voltage ABZ High impedance * In alarm state LED flashes red/green. Diagram 2: Transition time...

Status indicator LED After installation of the magnetic scale or ring (for MSD01, MR01D01 or MR02D02 data sheet refer to RLS Media Center), the readhead can be easily adjusted on the machine using the set-up LED indicator. Error output (special option 07) LED Signal Good signal strength/set-up Poor signal strength. Possible reasons: • Incorrect readhead orientation. • Readhead installation out of tolerance. • Demagnetisation of measuring scale. • Insufficient power supply voltage.
