Economical solutions and innovative technologies for industrial applications The MagLine range is a classic example of SIKO’s innovative power. The systems are based on the magnetic measurement principle. Special benefits of MagLine: �¡�¡ Completely wear-free �¡�¡ Insensitive to dust, shavings, humidity, oil, fat, etc. �¡�¡ Very robust with shock and vibration �¡�¡ No measurement errors caused by gear ratios or gear backlash �¡�¡ High system accuracy and reproducibility �¡�¡ Easy handling and mounting The challenges faced by measuring devices in extreme industrial conditions make great demands on their reliability and reproducibility. MagLine systems are mainly used for extremely precise tracking of linear and radial positions as well as speeds and angles. The contactless technology demonstrates its advantages in all kinds of applications, such as motor feedback or highly dynamic processes in particularly dirty environments. Since its introduction, MagLine has undergone continuous further development. Four product families provide a general overview: Micro, Basic and Macro for linear length measurement and Roto for angle and speed measurement. What is the measurement assignment? The following selection criteria indicate the right MagLine system solution: �¡�¡ Linear or rotating applications �¡�¡ Incremental/absolute processes �¡�¡ System accuracy and reproducibility requirements �¡�¡ Integration into upstream control systems or independent measuring systems Featuring a constantly expanding spectrum of components in various specifications, MagLine is designed for a number of special tasks. The technology offers future-oriented, extremely versatile and flexible measuring solutions, which are easily integrated and can be continually extended in line with customers’ requirements. Its easy handling and mounting have won MagLine a reputation as a paticularly customer-friendly product line which is universally durable and economical. Magnetic encoding The SIKO magnetic bands (flexible steel strips with a magnetic layer) are manufactured precisely and with great care. The bands are equipped with one or more magnetic code tracks in specially developed processes. The scanning principle is determined by this encoding. Incremental encoding serves for robust and all-round solutions with which, for example, flexible magnetic bands can be individually cut to length before self-adhesive mounting. The absolute encoding of the band material ensures that the system features a particularly high standard of reproducibility and measuring reliability. Its easy handling and mounting have won MagLine a reputation as a particularly customer-friendly product line, which is universally durable and economical. After power interruptions, for example when the system is switched off and on once more, the actual position value is determined and converted, even if the sensor position has changed in the meantime. Incremental and absolute encoding methods enable position tracking with different forms of feedback which can be evaluated in various ways (see diagram) SPS SPS MS-Sensors 80818 8 MSK-Sensors LE/LS-Sensors System signals for SIKO magnetic displays und SIKO translation modules Digital signal Analog signal Magnetic band Incremental encoded Incremental band encoding 1 Code track Sensor 80818 8 Magnetic band 2.
