Optical blind / through hollow shaft

Miniaturized EH 17 - EH 30 M encoder series, supplied as a kit, for integration in small sized AC/DC motors, stepper motors or for applications where reduced sizes are required. No wear due to the absence of bearings and easy assembly.

This new model represents an extension of the EH 17 - EH 30 series; it is a miniaturized incremental kit encoder, ideal for the integration on small size AC/DC motors, stepper motors and for applications that require reduced dimensions. The series has been improved with a significant increase of resolution (5.000 ppr), temperature range (-20° ... +85°C) and rotation speed (10.000 rpm), while maintaining the features of easy assembly and no wear.
