Custom and OEM Encoders for Robotics

Lika, custom and OEM encoders for robotics

Technavio’s analysts forecast the Robotics market to grow impressively at a CAGR of over 15% in Europe and at a CAGR of over 12% in the USA by 2020. To meet the requirements of a such booming sector and of the automation world in general, Lika Electronic develops and manufactures specific custom-designed incremental and absolute modular encoders, in both optical and magnetic configuration.

Lika’s products and solutions are engineered for direct integration into automation systems that need compact and accurate devices for high-precision position and speed feedback operations. Both the mechanical characteristics (through hollow shaft bore diameter, PCB shape and size, etc.) and the electrical features (resolution, interface, type of connection, etc.) can be easily and quickly tailored to meet individual requirements. Thanks to the compact and low-profile design, they can be integrated comfortably, while the bearingless and contactless mechanics preserves them from wear and fatigue. Measuring systems with magnetic ring are further distinguished by the high degree of protection (up to IP69K) and the very large bores for installation in diameters up to 300 mm (11.811”). The fully overmolded electronics is an additional benefit and ensures excellent durability under harsh environments affected by dirt, lubricants, dusts, etc. Sensing heads can be paired with custom size rings in order to accurately and reliably detect position values and speeds up to 100,000 rpm. Optical modular encoders are very high resolution devices and equipped with through hollow shaft, so they are ideally suited for advanced industrial machinery, thru-bore motors and linear guides. The high singleturn resolution up to stunning 25 bits and the multiturn resolution up to 16,384 rev. allow also for real-time control of very long travels.

AMM8A is an optical frameless encoder (kit encoder) with multiturn resolution up to 34 bits (1,048,576 cpr x 16,384 rev.). It is equipped with BiSS C-mode interface. It further integrates an additional Sine Cosine track with 1,024 sinusoidal signals per revolution.

ASM36 is an optical frameless encoder (kit encoder). It is miniature (Ø 35 mm / 1.378”) and provides singleturn resolution up to 21 bits (2,097,152 cpr).
Interface is BiSS C-mode with an additional Sine Cosine track that provides 256 sinusoidal signals per revolution.

ASC85 is a rotary encoder fitted with large 50 mm / 1.968" through hollow shaft. It provides high 25 bit singleturn resolution and high accuracy (±0,005°). The shaft clamping system by fixing plate and three eccentric screws allows to reduce the overall encumbrance. SSI / BiSS C-mode interfaces.

SMAB + MRAB is a magnetic modular encoder with low profile sensor head + 80 mm / 3.149” thru-bore flat ring. It features an unconventional installation, poles are oriented axially, the sensor head is mounted over the flat surface of the ring instead of radially as usually. The protection rate is up to IP69K. It offers 16-bit resolution and SSI / BiSS C-mode interfaces.

SMLA absolute encoder + MRA/262 segmented ring easily fit around large shafts in inaccessible mounting areas. SMLA is paired with a ring that is expressly designed and segmented into two pieces for simplified installation in large diameter shafts up to 190 mm / 7.48” where access for mounting or servicing is difficult. It provides 15-bit resolution through SSI or BISS interface.
