Product catalog summary

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

Main Features: The encoders are designed for harsh environments with high mechanical resistance. They offer up to 10000 pulses per revolution (ppr), various power supply options up to +28 VDC, and multiple electronic interfaces. The encoders have a metal cover for heavy-duty applications and can be mounted using synchronous or REO-444 flanges.

Electrical Specifications: The encoders support resolutions from 1 to 10000 ppr, with power supply options ranging from 4.5 to 29.4 V DC. They have a power draw of 800 mW without load and support various output types including NPN, push-pull, and line driver. The maximum output frequency is 500 kHz.

Mechanical Specifications: Shaft diameters range from 8 to 11 mm, with enclosure ratings of IP 54 and IP 66. The maximum rotation speed is 6000 rpm for IP 54 and 3000 rpm for IP 66. The encoders can withstand shocks of 50 G and vibrations of 10 G. They are made from aluminum and stainless steel, with a weight of 750 g.

Connections: The document details the connections for various output types, including cable and connector outputs, with specific pin assignments for each function.

Resolutions: The document lists available resolutions for both EL and ER series encoders, with preferred resolutions highlighted in bold.
