*1. An inrush current of approximately 9 A will flow for approximately 5 μs when the power is turned ON.
*2. Complementary Outputs
The complementary output has two output transistors (NPN and PNP) as shown at the right. These two output transistors
alternately turn ON and OFF depending on the high or low output signal. When using them, pull up to the positive power
supply voltage level or pull down to 0 V. The 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 opencollector input devices (NPN, PNP).

Safety Precautions
Refer to Warranty and Limitations of Liability.
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.
● Wiring
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.
* Recommended Cable
Conductor cross section: 0.2 mm2
Spiral shield
Conductor resistance: 92 Ω/km max. (20°C)
Insulation resistance: 5 Ω/km min. (20°C)
• 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.
• When the complementary output is used, the output will turn OFF
when the load short-circuit protection circuit operates. To clear this
condition, turn OFF the power supply, check the condition of the
