Explanation of the selection tables

The tables on the following pages list the encoders suited for

individual motor designs. The encoders are available with

dimensions and output signals to ﬁ t speciﬁ c types of motors (DC

or AC).

Rotary encoders for mounting on motors

Rotary encoders for motors with forced ventilation are either built

onto the motor housing or integrated. As a result, they are

frequently exposed to the unﬁ ltered forced-air stream of the motor

and must have a high degree of protection, such as IP 64 or better.

The permissible operating temperature seldom exceeds 100 °C.

In the selection table you will ﬁ nd:

• Rotary encoders with mounted stator couplings with high

natural frequency—virtually eliminating any limits on the

bandwidth of the drive

• Rotary encoders for separate shaft couplings, which are

particularly suited for insulated mounting

• Incremental rotary encoders with high quality sinusoidal

output signals for digital speed control

• Absolute rotary encoders with purely digital data transfer or

complementary sinusoidal incremental signals

• Incremental rotary encoders with TTL or HTL compatible

output signals

• Information on rotary encoders that are available as safety-

related position encoders under the designation Functional

Safety .

Rotary encoders for integration in motors

For motors without separate ventilation, the rotary encoder is built

into the motor housing. This conﬁ guration places no stringent

requirements on the encoder for a high degree of protection. The

operating temperature within the motor housing, however, can

reach 100 °C and higher.

In the selection table you will ﬁ nd

• Incremental rotary encoders for operating temperatures up to

120 °C, and absolute rotary encoders for operating temperatures

up to 115 °C

• Rotary encoders with mounted stator couplings with high

natural frequency—virtually eliminating any limits on the

bandwidth of the drive

• Incremental rotary encoders for digital speed control with

sinusoidal output signals of high quality—even at high

operating temperatures

• Absolute rotary encoders with purely digital data transfer or

complementary sinusoidal incremental signals

• Incremental rotary encoders with additional commutation

signal for synchronous motors

• Incremental rotary encoders with TTL-compatible output

signals

• Information on rotary encoders that are available as safety-

related position encoders under the designation Functional

Safety .
