Product catalog summary

Ordering Code: The document provides a detailed ordering code for Eltra's incremental encoders, specifying series, model, motor poles, electronic interface, resolution, zero pulse, power supply, electronic interface, bore diameter, enclosure rating, max rotation speed, output type, and variant.

Main Features: The EH and EF series encoders are designed for feedback control systems on AC servomotors, featuring easy mechanical mounting, compact dimensions, a wide range of resolutions, and high temperature resistance.

Electrical Specifications: The encoders offer resolutions from 200 to 2048 pulses per revolution (ppr), with power supply options ranging from 4.5 to 29.4 V DC. They support various output types including NPN, push-pull, and line driver, with a maximum output frequency of 105 kHz. The encoders comply with electromagnetic compatibility standards IEC 61000-6-2 and IEC 61000-6-4.

Mechanical Specifications: The encoders have bore diameters of 8, 10, 14, and 15 mm, an enclosure rating of IP 54, and can operate at maximum rotation speeds of 3000 or 6000 rpm depending on the model. They are built with PA66 glass fiber reinforced body and housing materials, and stainless steel shafts, with a shock resistance of 50 G and vibration resistance of 20 G.

Resolutions and Connections: The document lists available resolutions and corresponding motor poles, as well as detailed connection information for EH and EF series encoders, including color-coded wiring for various channels.

Accessories: An antirotation pin is available as an accessory, with specific part number and dimensions provided.
