Of HEIDENHAIN's 400 series, the ECN/EQN 400 rotary encoders with stator couplings are available with a blind-hollow or hollow through-shaft.

The TSI40 recessed hollow-shaft encoders are available with shaft bore sizes of 3/16 in., 1/4 in., 5/16 in. and 3/8 in. shaft couplings.

Featuring a new shaft coupling that provides mechanical fault exclusion for connection to the user’s machine shaft, the encoders are of particular use in safety-related applications up to SIL 2 PL d ...

The encoder shaft couples to the motor shaft with a belt, coupling, or gear train. Hollow shaft encoders are similar, but the motor shaft fits into the encoder shaft bore.

Additional features include a 10 mm or 12 mm diameter shaft bore, an alarm output, and operating voltages of 10V to 30V or 5V. PEPPERL+FUCHS, Twinsburg, OH. (330) 486-0001. Company:PEPPERL+FUCHS ...

SICK’s new large bore hollow-shaft encoder family therefore gives end-users and machine builders the confidence of universal machine compatibility while stocking minimal inventory. The DGS80 is also ...

For the latter, perfect alignment of encoder and driving shaft centers of rotation is impossible, so flexible couplings are often used. Manufacturers offer detailed guidelines on proper mounting.
