The complementary output has two output
transistors (NPN and PNP) as shown below. These

using them, pull up to the positive power supply
voltage level or pull down to 0 V. The
PNP
complementary output allows flow-in or flow-out of

the output current and thus the rising and falling

speeds of signals are fast. This allows a long cable
distance. They can be connected to open-collector
input devices (NPN, PNP).
*3. The line driver output is a data transmission circuit compatible with RS-422A and long-distance transmission is possible with a twisted-pair cable. (AM26LS31
equivalent)
*4. The maximum electrical response speed is determined by the resolution and maximum response frequency as follows:

This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed.

WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Do not use the Encoder under ambient conditions that exceed the
ratings.

Cable Extension Characteristics
•
When the cable length is extended, the output waveform startup
time is lengthened and it affects the phase difference
characteristics of phases A and B. Conditions will change
according to frequency, noise, and other factors. As a guideline,
use a cable length of 10 m* or less. If the cable must be more than
10 m, use a Model with a Line-driver Output or Complementary
Output.
(max. length for line-driver output: 100 m,
max. length for complementary output: 30 m)

•
The output waveform startup time changes not only according to
the length of the cable, but also according to the load resistance
and the cable type.
•
Extending the cable length not only changes the startup time, but
also increases the output residual voltage.
●
Connection
Spurious pulses may be generated when power is turned ON and
OFF. Wait at least 0.1 s after turning ON the power to the Encoder
before using the connected device, and stop using the connected
device at least 0.1 s before turning OFF the power to the Encoder.
Also, turn ON the power to the load only after turning ON the power
to the Encoder.
