Rotary and Linear Encoders

For commutation, digital velocity and positioning control of our motors we use linear and angular sensors. We supply feedback systems with 3 physical principles:

• Electrical sensors
• Magnetical sensors
• Optical sensors

These sensors use the capacitive principle. They have specific advantages regarding size, sensibility, power consumption and can be easily adapted to batch applications. The electrical sensors provide an absolute position information within one rotation (360°). 

RECKONIC is the exclusive distributor for the Netzer electrical encoders for the German speaking countries.

Magnetic sensors are often used because of their robustness, modularity and insensibility regarding high and low temperatures

• Resolvers by Tamagawa, LTN, Alxion, Harowe, Artus
• Inductosyn
• Magnetoresistive sensors by AMO and Baumer-Huebner

Optical sensors are the most common sensors in position control applications. Therefore we find the biggest variety of types and dimensions in this technology.

These sensors supply the highest accuracy. We use them in our own applications and distribute sensors of the following companies:

• Heidenhain
• SICK-Stegmann
• Renishaw
• Numerik Jena
• Avago

For precise velocity control and disturbance suppression at axis with analog amplifiers the DC-Tachometer is still the best solution. Please ask for our catalogue.
