SMG: the miniature modular encoder for toothed-wheels and racks 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.

SMG modular encoder is typically intended for speed and position feedback in industrial applications up to 100,000 RPM such as HSC High resolution and accuracy can be achieved by means of an interpolation factor up to x100. Cable outlet can be axial and radial.
