An inrush current of approximately 6 A will flow for approximately 0.3 ms when the power is turned ON. *2. The maximum electrical response speed is determined by the resolution and maximum response frequency as follows: Maximum response frequency x 60 Maximum electrical response speed (rpm) = Resolution This means that the Rotary Encoder will not operate electrically if its speed exceeds the maximum electrical response speed. *3. No protection is provided against water or oil. *4. 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. 2 E6H-C I/O Circuit Diagrams Model Output Circuits Output mode Connection Open-collector output Direction of rotation: CW (as viewed from end of shaft) T(360) Brown 5 to 24 VDC Black, white, orange E6H-CWZ6C E6H main circuit NPN transistor 35 mA max. 35 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 Correct Use Do not use the Encoder under ambient conditions that exceed the ratings. Mounting * When securing the Encoder, use two M3 screws to secure the leaf spring to the mounting surface. * Use the Allen set screw provided with the hollow shaft to secure the shaft. Use a tightening torque of 0.4 N*m and apply screw lock glue to the screw to prevent it from becoming loose. * If wiring after securing the Encoder, do not pull on the cable. Also, do not apply shock to the Encoder or hollow shaft. * If the Encoder phase Z must be aligned with the origin of the installation device, mount the Encoder while checking the phase Z output. * The diameter of the mating shaft must be 8 -0.012 -0.004 mm and 8 to 11 mm long from the mounting surface. * The allowable displacement in the mating shaft must 0.05 mm in the radial direction and 0.3 mm in the thrust direction. * The mounting surface and shaft must be perpendicular to within 0.03 mm. * When securing the Encoder, do not allow force to be applied to the leaf spring. 0.03 A 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. Eccentricity will develop in the Encoder if the above values are not satisfied, and the mounting leaf spring may be destroyed.
