Engrenages, Codeur, Codeur magnétique
Lika Electronic continues its commitment to expanding the application specific product range by introducing to the market the new SMG incremental modular encoder for toothed-wheels and racks.
SMG is the incremental modular encoder from Lika Electronic specifically designed to sense a variety of toothed profiles with different pitches in both rotary and linear installations such as toothed-wheels and racks. It features a very compact and space-saving bearingless design with dependable magnetic scanning. The magnetoresistive sensor head measures only about 40 x 20 h mm (1.57” x 0.79”) with a very shallow profile (17-mm / 0.67” thickness). The extremely small dimensions enable the encoder to be easily mounted on spindles, drives and electric motors. SMG is contactless and wear-free; furthermore it is insensitive to dust, water, oil, grease and interferences thanks to the rugged metal enclosure and the full circuitry encapsulation (IP68 protection rate). Thus it offers virtually maintenance-free enduring service even in the most demanding conditions and under moisture, vibrations and mechanical stresses. SMG is designed to provide either AB digital signals with complementary through Line Driver output circuit or sine-cosine signals through 1Vpp output circuit. An additional Reference signal can be provided on request. The pulse frequency is up to 200 kHz. High resolution and accuracy can be achieved by means of an interpolation factor up to x100. Cable outlet can be axial and radial. As stated, SMG is ideally suited for speed and position detection in a variety of toothed profiles in both rotary & linear applications. The sensor is available with different pitches to accommodate several modules (typically M0.3 and M0.5). Standard ferromagnetic wheels with optional module versions can be provided; customized wheels and application solutions with diameters, modules and tooth profiles on request are further available to meet specific requirements.
SMG modular encoder is typically intended for speed and position feedback in industrial applications up to 100,000 RPM such as HSC (High Speed Cutting) spindles of lathes and mills, machine tools and CNC machining centres; assembly equipment, industrial robots and manipulators, welding equipment, torque motors and drive systems in general.
For dependable measurements on toothed-wheels and racks we can provide the ICS model (http://www.lika.it/eng/prodotti2.php?idprod=54&ID=1) as well. It operates using pinion + metric wheel or pinion + rack assemblies and is available in both incremental and absolute versions.
