EAM 58 B / C - 63 A / D / E PROFIBUS

Product catalog summary

Main Features:
The EA 63 AX / DX is a stainless steel singletur absolute encoder designed for environments requiring high corrosion resistance, such as food and beverage machinery, marine applications, and washing systems. It features optical sensor technology (OptoASIC) with a resolution of up to 13 bits (8192 ppr) and supports a power supply of up to +28 VDC with a PROFIBUS DP electronic interface. The encoder includes a cable gland output and a solid shaft diameter of up to 10 mm, with mounting options via clamping or centering a 2.5” square flange.

Ordering Code:
The ordering code for the encoder includes specifications for series, model, resolution, code type, power supply, electronic interface, shaft diameter, enclosure rating, max rotation speed, output type, and variant.

Mechanical Specifications:
The encoder has a shaft diameter of 9.52 mm (3/8”) or 10 mm, an enclosure rating of IP 66, and a maximum rotation speed of 3000 rpm. It can handle a maximum shaft load of 100 N axial/radial, withstands shocks of 50 G for 11 ms, and vibrations of 10 G from 10 to 2000 Hz. The moment of inertia is 1.5 x 10^-6 kgm², with a starting torque of less than 0.06 Nm at +20°C. The body, shaft, and housing materials are made of 1.4305 / AISI 303 stainless steel, and it includes two ball bearings with a life of 10⁹ revolutions. The operating temperature range is 0° to +60°C, and the storage temperature range is -15° to +70°C. The weight is 1200 g.

Electrical Specifications:
The encoder's resolution ranges from 2 to 4096 or 8192 ppr, programmable during commissioning. It requires a power supply of 11.4 to 29.4 V DC and has a current consumption of 300 mA without load. The output type is RS 485 galvanically isolated, with a maximum bus frequency of 12 Mbaud. Diagnostic features include frequency and position warnings/alarms. The maximum frequency is 25 kHz LSB, with an accuracy of ± 1/2 LSB. The counting direction is programmable during commissioning, and the start-up time is 500 ms. It complies with electromagnetic compatibility standards IEC 61000-6-2 and IEC 61000-6-4.
