LM13
LM13

The LM13 sensor consists of a sealed measuring head that moves over a magnetic self-adhesive scale with a clearance of up to 1.5 mm and can have a measurement range of up to 100 m.

The sensor head has a built-in LED indicator for the correct position of the head and the serviceability of the sensor. The absence of rigid tolerances and special equipment for mounting the magnetic tape simplify the installation of the LM13. The reference mark can be pre-installed on a magnetic scale or glued over the tape with a self-leveling device, which greatly simplifies the installation process.

The LM13 sensors are manufactured only with digital output and have resolutions of 1, 2, 5, 10, 20, 25, 50, 125 and 250 microns. At the maximum resolution (1 μm), the LM13 travel speed reaches 4 m/s.

Due to its compact dimensions and internal construction, the LM13 is also suitable for designs with curved magnetic tape. Self-adhesive magnetic tape can be installed on a surface with a bend radius of 60 mm or more.

Designed for harsh environments, linear sensors have a process temperature range of -20 to + 85 ° C and a degree of protection - IP68, are highly resistant to shock, vibration and pressure. The magnetic scale is resistant to chemicals used in various industries. Non-contact reading of LM13 ensures the absence of friction and wear of the components of the measuring system, mechanical hysteresis at maximum speed and acceleration.

The LM13 sensors guarantee reliable operation in harsh and difficult operating conditions, they are successfully used in woodworking, stone processing, metalworking, textile, printing, plastics industries and in the packaging industry. They are also suitable for automation systems and assembly lines, for laser, plasma and waterjet cutting, microchip production, printed circuit boards, etc.
