Slim-design encoders fit in compact applications

Heidenhain has introduced the slim-design ECI 1118 rotary encoder. With a thickness of 0.39 in. and a diameter of about 1.46 in., the encoder can fit into compact applications. Resolution is 18 bits, and accuracy is +/-120 in.

The encoder’s counterpart is the EBI 1135 model rotary encoder, which has the same slim design and single-turn feedback while also offering the option for multiturn capabilities via a battery-buffered revolution counter. This revolution counter can attain distinguishable revolutions up to 16 bits with an external battery connected.

Both encoders offer noncontact design, resistance to contamination, no mechanical self-heating, reduced sensitivity to radial runout, and a high tolerance to vibration and shock.
