Draw-Wire Encoder Advantages

Draw-wire encoders are a little-known type of measuring system.
That's why they are seldom considered when it comes to designing a new solution for an industrial application. But there are a number of good reasons why designers should appreciate their functional characteristics and discover that sometimes they can be an excellent answer to measuring needs.

  • Measuring lengths from 2 m (3.28 ft), 5 m (16.4 ft), 10 m (32.8 ft), and up to 50 m (164 ft)
  • Any type of encoder can be integrated: incremental, absolute, fieldbus, Ethernet, analogue (including potentiometer), ATEX, special models for individual applications
  • Resolution down to 0.01 mm / 10 µm
  • Speed up to 2 m per second / 78.7 inches per second

AMM33 modular encoder integrates energy harvesting technology

AMM33 multiturn modular magnetic encoder from Lika Electronic uses Energy Harvesting Technology to produce electricity and power the multiturn counter. The battery and multiturn mechanical gears that equips the standard multiturn counters can be eliminated.

Energy Harvesting Technology uses variations in the magnetic field to generate electricity.
This pulse of electricity is sufficient to power the multiturn tracking circuitry and write the turns count to non-volatile memory. Batteryless multiturn design gives several advantages over the common geared multiturn versions: the elimination of the gears in fact provides more compactness, reduces the issues related to wear and increases the accuracy of the measuring system at the same time. It's the perfect solution for servomotor feedback applications.

Miniature and high IP protected SMAR3 modular encoder

SMAR3 is the new off-axis absolute singleturn modular encoder from Lika.
It offers a fully protected one-piece readhead instead of an open PCB readhead and shares the MRA magnetic ring with the other models of the SMAR series. SMAR3 has an ultra-compact and ultra-flat readhead, it is only a few millimetres in size. Its robust construction with encapsulated electronics and IP67 protection rate enables the measuring system to be installed in harsh industrial environments affected for instance by contaminants, dust, humidity, oil, cooling lubricant emulsion as well as susceptible to vibrations and temperature fluctuations.
Also the ring is very thin and axially magnetized and has an outer diameter of 34 mm with max. 18 mm through bore. Thanks to the minimum size and weight (only a few grams) the SMAR3 is also suitable for integration into space and weight critical applications such as into robotic joints, hollow shaft motors (direct drive torque motors, …), brushless and servo motors, OEM equipment.

SOIC/SOAC Encoders for Hydraulic and Pneumatic Cylinders

SOIC/SOAC encoders are designed for high precision and high resolution (down to less than 50 µm) position sensing in hydraulic and pneumatic cylinders. Available in both incremental and absolute versions, their installation is very simple and non-invasive.

They offer several advantages over the measuring solutions that are commonly adopted on cylinders. They are easy to install on any type of cylinder and do not need customization such as dedicated mechanics or additional space for mounting internal parts. What's more, they do not require any invasive (and expensive) mechanical machining and the rod must not be drilled, so it preserves its whole robustness.
Also, they let you save time and money as the sensor is easily mounted on the outside of the cylinder housing (a great benefit, for example, should a replacement be required).
