An inrush current of approximately 9 A will flow for approximately 0.1 ms when the power is turned ON. *2. Complementary Output Power E6C3-CWZ5GH supply The complementary output has two output transistors (NPN and PNP) as shown below. These NPN two output transistors alternately turn ON and OFF transistor depending on the high or low output signal. When OUT Signal 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 transistor the output current and thus the rising and falling 0V 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: Maximum response frequency Maximum electrical response speed (rpm) = × 60 Resolution This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed. *5. The phase Z signal is output when cut face D on the shaft and the cable connection direction are as shown in the following diagram (output position range: ±15°). 120˚ Cut face D 120˚ 40 dia. 2 E6C3-C I/O Circuit Diagrams Model/Output Circuits Output mode Connection E6C3-CWZ5GH Brown 7.5 Ω 30mA max.

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 Connections 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) * 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. (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
