HEIDENHAIN’s ERO Miniature Modular Encoders Suited for Many Motion Control Applications

HEIDENHAIN is offering the ERO 1200/1400 series of modular optical rotary encoders without integral bearing. Being a non-contact solution, the ERO 1200/1400 encoders are well suited for motion control use on dynamic stages and machines in the general automation or semiconductor industries, such as a pick and place machines. They are also used on air bearing spindles, blood pumps, and servo motors in robotic applications.

With onboard interpolation, the ERO 1400 can achieve resolutions of 37,500 signal periods per revolution, facilitating use on high-resolution viscosimeters or portable mass spectrometers.

Thanks to the bearingless design, the ERO 1200/1400 encoders allow axial motion up to ±0.02mm, providing room for thermal growth of motors or machines. This encoder series supports line driven TTL outputs (RS422), as well as differential one volt peak-to-peak signals, which can be interpolated for use in a speed control loop.

With through-shaft diameters of 4, 6, or 8 mm, and a self-centering slide mechanism, the ERO 1400 is a small, versatile encoder with onboard interpolation and easy mounting. The ERO 1200 is available with a 10mm or 12mm shaft, offering a graduation accuracy of ±6 arc seconds.
