Rotary Encoders measure the number of rotations, the rotational angle, and the rotational position. Linear Encoders are also available to measure linear movement.

Bearing Life | Cable Extension Characteristics |
E6B2-C | E6B2-CWZ6C Measurement Example Power supply voltage: 5 VDC Load resistance: 1 kΩ (Output residual voltage is measured at a 35 mA load current.) Cable: Special Cable |
・ This graph shows the relationship between mechanical life and the load applied to the shaft. ・ The size of the load during rotation affects the life of the bearings. | ・ This graph shows the effect of the output waveform if the cable is extended. ・ Extending the cable length not only changes the startup time, but also increases the output residual voltage. |
Mounting
To mount the Rotary Encoder directly, secure it with screws from direction A. If a servo mount is used, attach a Flange to the Rotary Encoder and mount the Rotary Encoder from direction B.
Example: Attaching an E69-FCA02 Flange to the E6C2-C
