An inrush current of approximately 9 A will flow for approximately 0.3 ms when the power is turned ON. *2. The line driver output is a data transmission circuit compatible with RS-422A and long-distance transmission is possible with a twisted-pair cable. The quality is equivalent to AM26LS31. *3. The maximum electrical response speed is determined by the resolution and maximum response frequency as follows: Maximum response frequency × 60 Maximum electrical response speed (rpm) = Resolution This means that the E6B2-C Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed. 2 E6B2-C I/O Circuit Diagrams Model/Output Circuits Output mode Connection E6B2-CWZ6C Brown 5 VDC -5% to 24 VDC +15% Black, white, orange NPN transistor 35 mA max. at 30 VDC 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 Safe Use Incorrect wiring may damage internal circuits. Precautions for Correct Use Do not use the Encoder under ambient conditions that exceed the ratings. ● Mounting • Origin Indication It is easy to adjust the position of phase Z with the origin indication function. The following illustration shows the relationship between phase Z and the origin. Set cut face D to the phase Z origin as shown in the illustration. Phase Z origin Origin 120˚ 120˚ Cut face D • Do not extend the length of the cable to more than 2 m. If the cable must be more than 2 m, use a Model with a Line-driver Output (max. length: 100 m). ● Wiring 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. 30±0.2 dia.
