Mounting the ECN/EQN/ERN 1000 and

ERN 1x23

The rotary encoder is slid by its hollow

shaft onto the measured shaft and

fastened by two screws or three eccentric

clamps. The stator is mounted without a

centering ﬂ ange to a ﬂ at surface with four

cap screws or with 2 cap screws and

special washers.

The ECN/EQN/ERN 1000 encoders feature

a blind hollow shaft, the ERN 1123 a hollow

through shaft.

Mounting the EQN/ERN 400

The EQN/ERN 400 encoders are designed

for use on Siemens asynchronous motors.

They serve as replacement existing

Siemens rotary encoders.

The rotary encoder is slid by its hollow

shaft onto the measured shaft and

fastened by the clamping ring. On the

stator side, the encoder is ﬁ xed by its

torque support to a plane surface.

Mounting the EQN/ERN 401

The ERN 401 encoders are designed for

use on Siemens asynchronous motors.

They serve as replacement existing

Siemens rotary encoders.

The rotary encoder features a solid shaft

with a M8 external thread, centering taper

and SW8 width across ﬂ ats. It centers

itself during fastening to the motor shaft.

The stator coupling is fastened by special

clips to the motor’s ventilation grille.
