EH 90 A - EH 115 A / R

Product catalog summary

Main Features: The EH 90 A and EH 115 A/R are solid shaft incremental encoders designed for harsh environments requiring high mechanical resistance. The EH 90 model can be mounted using flanges or fixing clamps, while the EH 115 model includes a tachometer generator compatible plug with an optional centrifugal relay. Key features include a 3-channel encoder (A/B/Z) with resolutions up to 2048 pulses per revolution (ppr), redundancy with double electronics and/or resolutions, power supply up to +24 VDC, and output frequency up to 100 kHz. The solid shaft diameter is up to 11 mm, and mounting options include synchronous or REO-444 flanges.

Ordering Code: The ordering code specifies the series, model, resolution, zero pulse, power supply, electronic interface, shaft diameter, enclosure rating, max rotation speed, output type, direction type, variant, and relay intervention speed. Examples of ordering codes are provided for different configurations.

Electrical Specifications: The encoders offer resolutions from 200 to 2048 ppr, with power supply options of 5 V DC or 8/24 V DC. Current consumption without load is 100 mA max, and max load current varies by output type. The max output frequency is 100 kHz, and counting direction is specified. Electromagnetic compatibility is in accordance with IEC standards.

Mechanical Specifications: Shaft diameters range from 8 to 11 mm, with enclosure ratings of IP 54 or IP 66. Max rotation speeds are 6000 rpm (IP 54) and 3000 rpm (IP 66). The encoders can withstand shocks of 50 G and vibrations of 10 G. Materials include EN-AW 2011 aluminum for the body and AISI 303 stainless steel for the shaft. Operating temperature ranges from -10°C to +60°C.

Relay Characteristics: The relay intervention speed ranges from 600 to 4300 rpm with an accuracy of ±3%. Contact capacity is specified for different voltages, and the type of contact is Normally Closed (NC).

Connections: Detailed connection information is provided for various output types and connector configurations, including pin assignments and color codes for cable outputs.

Accessories: Accessories include a set of three fixing clamps for model 90 A.
