Product catalog summary

Ordering Code: The ordering code for the EH 50FP encoder includes specifications such as series, model, resolution, zero pulse, power supply, electronic interface, bore diameter, enclosure rating, max rotation speed, output type, and variant. For example, the code 'EH 50FP 1024 S 5/30 P 6 X 6 PR . XXX' specifies an incremental encoder with a through hollow shaft, 1024 ppr resolution, no zero pulse, 5-30 V DC power supply, push-pull interface, 6 mm bore diameter, IP 65 rating, 6000 rpm max speed, radial cable output, and a custom version.

Main Features: The EH 50FP encoder is a 50 mm diameter incremental encoder suitable for motor feedback, especially for small motors due to its compact size. It features a 3-channel encoder (A/B/Z) with up to 1024 pulses per revolution (ppr), a highly integrated optical ASIC, a wide power supply range up to +30 VDC, and a through hollow shaft up to 10 mm diameter. It offers IP 65 protection and operates in a temperature range of -40 to +100°C.

Electrical Specifications: The encoder supports resolutions from 100 to 1024 ppr, with a power supply range of 4.5 to 30 V DC and reverse polarity protection. It has a power draw of 600 mW without load, a max load current of 20 mA per channel, and a max output frequency of 105 kHz. The counting direction is A leads B clockwise from the shaft view. It complies with IEC 61000-6-2 and IEC 61000-6-4 for electromagnetic compatibility.

Mechanical Specifications: The encoder has bore diameters of 6, 8, 9.52 (3/8”), and 10 mm, with an IP 65 enclosure rating. It supports a max rotation speed of 6000 rpm, shock resistance of 50 G for 11 ms, and vibration resistance of 10 G from 10 to 2000 Hz. The moment of inertia is 0.5 x 10^-6 kgm², with a starting torque of less than 0.01 Nm at 20°C. The body and housing are made of EN-AW 2011 aluminum, while the shaft is made of 1.4305/AISI 303 stainless steel. It includes two ball bearings with a life of 10⁹ revolutions. The operating and storage temperature range is -40 to +100°C.

Connections: The encoder provides cable outputs for line driver and push-pull interfaces, with specific color codes for each function such as +V DC (red), 0 V (black), Ch. A (green), Ch. B (yellow), and Ch. Z (blue).

Resolutions: Available resolutions include 100, 200, 256, 360, 400, 500, 1000, and 1024 ppr, with preferred resolutions highlighted in bold. For other pulse options, contact the company directly.
