Encoders

Encoders are devices designed to measure motion or position. They are commonly used to measure the rotational position of a shaft or axle by recording the number of rotations that have occurred. Encoders are available in a variety of configurations, including incremental, absolute, relative, linear, and rotary encoders.

EN11-HSM1BF30 Application Field

The EN11-HSM1BF30 is a high performance incremental optical rotary encoder designed for servo motors, and is suitable for the most demanding applications. Available in a variety of resolutions and various mounting configurations, the EN11-HSM1BF30 is compatible with both linear and rotary motion, and is designed to provide feedback and control for positioning, speed control, torque control and other motion control applications.

EN11-HSM1BF30 Working Principle

The EN11-HSM1BF30 utilizes an LED source and an optical disk having transparent and opaque areas that represent a decimal series of specific counts per revolution of the encoder’s output shaft. The optical disk is mounted on the output shaft of the motor. As the shaft rotates, the LED source sends a beam of light through the disk. As the beam of light passes through the disk, it is either interrupted or allowed to pass through. Those light pulses are then received by a four-layer photodiode and the pulse count is electronically determined, providing an output of binary data.

The EN11-HSM1BF30 provides both direction and speed feedback as well as index pulse feedback. It is capable of various resolutions that depend on the number of teeth on the optical disk, and the count rate can reach up to 790,000 pulses per revolution (PPR). This type of encoder is also designed to operate with extremely low power consumption, typically below 0.5 watts. In addition to its small form factor and low power consumption, the EN11-HSM1BF30 offers an unparalleled combination of features, including fast, accurate indexing, high cycle rates, high shock/vibration immunity and low noise operation.

Conclusion

The EN11-HSM1BF30 optical rotary encoder is ideal for motion control applications that require fast, accurate position feedback and control. Its high resolution, low power consumption, and shock/vibration immunity make it a perfect fit for servo motor applications. With a range of mounting options and resolutions, the EN11-HSM1BF30 is an excellent choice for a variety of motion control applications.
