EH 17 - 30 M

Product catalog summary

Ordering Code: The document provides a detailed ordering code for the EH 30M incremental encoder series, specifying options for model, resolution, zero pulse, power supply, electronic interface, bore diameter, enclosure rating, max rotation speed, output type, and variant.

Main Features: The EH 17 - 30 M series are miniaturized incremental kit encoders designed for small AC/DC motors and limited size applications. Key features include a 3-channel encoder (A/B/Z) with resolutions up to 1024 ppr, power supply up to +24 VDC, output frequency up to 100 kHz, and a compact, easy-to-assemble design without bearings.

Electrical Specifications: The encoders offer resolutions from 50 to 1024 ppr, with power supply options of 4.5-5.5 V DC or 7.6-25.2 V DC. Current consumption is 50 mA bidirectional, increasing to 100 mA with zero pulse. The maximum output frequency is 105 kHz, and the encoders are compatible with IEC 61000-6-1 and IEC 61000-6-4 standards.

Mechanical Specifications: The encoders have a bore diameter of 6 or 6.35 mm, with enclosure ratings of IP40 for model 17 and IP54 for model 30. They support a maximum rotation speed of 6000 rpm, shock resistance of 50 G, and vibration resistance of 10 G. The operating temperature range is -20°C to +60°C, with a storage range of -25°C to +70°C.

Connections: The document details the cable output connections for different electronic interfaces, including NPN, NPN open collector, push-pull, and line driver, with specific color codes for each channel and power supply.
