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.

IX inclinometers, accurate and reliable

Lika's IX inclinometers with analogue, CANopen and Modbus interface are rugged and accurate and provide reliable measurement of inclination even in critical environments such as construction vehicles, solar trackers, agricultural machinery, mobile cranes, forklifts, bucket trucks.

• IXA: 1-axis (0°÷360°) and 2-axis (±10°, ±30°, ±60°) current and voltage analogue inclinometer
• IXA R: redundant analogue version with duplicated electronics
• IXB / IXC: 1-axis (0°÷360°, ±180°) and 2-axis (±5° to ±60°) programmable CANopen inclinometer
• IXM: 1-axis (0°÷360°, ±180°) and 2-axis (±5° to ±60°) programmable Modbus inclinometer
• High resolution down to 0.001°, high accuracy down to ±0.05°.
• Rugged housing for reliable operation in harsh environments

CH59 gets a makeover

CH59 optical incremental encoder has been updated mechanically and electrically.
It adds Sine-Cosine signals for position and speed feedback and CD commutation signals for rotor control on BLDC motors. New mounting option with collar and fixing plate makes installation further easier.

• Compact incremental encoder for position and speed feedback
• Space-saving construction and several installation types
• AB0 /AB0 digital signals and high resolutions up to 204,800 PPR
• 1,024 Sine-Cosine signals + CD signals to control the position of the rotor
• For electro-medical applications, motor testbeds, feedback on gearless and servo motors

CH59 is ideally suited for electro-medical applications, analysis and laboratory equipment, testing instruments, motor testbeds, and also for gearless motors, servo motors (such as for semiconductor manufacturing machines), robotics and any installation in constricted spaces.

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).
