Encoder accessories Manufacturers online

Encoder accessories play a crucial role in the correct installation, reliable operation and protection of encoders.

Encoders are important components for measuring positions, angles and speeds in mechanical systems.

Below you will find a list of accessories offered for the safe operation of encoders:

1. Couplings:
Couplings connect the encoder to the shaft to be measured, transmit the torque and compensate for mechanical inaccuracies or misalignment between the encoder shaft and the drive shaft.

The following types of couplings can be found:

• Rigid couplings: Offer no flexibility, but are suitable for applications where shaft misalignment does not occur.
• Flexible couplings: Can compensate for small misalignments and vibrations, extending the life of the encoder.
• Spring steel couplings: Very flexible, ideal for applications with dynamic movements.

Use: Applications with small shaft misalignments or vibrations require flexible or elastic couplings to protect the encoder and ensure measurement accuracy.

2. Mounting flanges and adapters:
Mounting flanges and adapters enable stable attachment of the encoder to the system or machine. They provide mechanical support and ensure correct alignment of the encoder.

The following types of flanges are available:

• Servo flanges: Commonly used for mounting encoders in servo applications.
• Retaining flanges: Used for stable mounting in industrial environments.
• Adapter plates: Allow the encoder to be adapted to different shaft or housing sizes.

They have the following important features:

• Shielding: To prevent electromagnetic interference and ensure reliable signal transmission.
• Robustness: Cables and connectors often need to be resistant to harsh environmental conditions such as high temperatures, moisture or chemicals.
• Connector types: Encoders offer different connection types such as M12, M23 connectors or special industrial connectors.

Use: Robust, shielded cables are crucial for use in industrial environments, while flexible connectors support easy replacement and maintenance.

4. Terminals and retaining arms:
Clamps and retaining arms are used to secure hollow shaft encoders and help prevent unwanted rotation of the housing.

A distinction is made between the following types of holding arms:

• Rigid holding arms: Ensure a firm attachment and prevent movement of the housing.
• Flexible mounting arms: Allow a certain degree of flexibility and compensate for mechanical vibrations.

Application: Particularly important for hollow shaft encoders to ensure precise measurement and reduce mechanical stresses.

5. Indicators and signal converters:
Display devices show the measured values of the encoder in real time (e.g. position, angle of rotation or speed). Signal converters convert the encoder signals into formats suitable for control or evaluation.

There are the following types of signal converters:

• Analog-to-digital converters: Convert analog signals into digital formats and vice versa.
• Pulse counters: Count the pulses from incremental encoders and display them as position or speed values.
• Protocol converters: Convert signals into various protocols such as Profibus, Profinet or CANopen.

Use: These devices are useful if the measurement data needs to be monitored directly or transferred to the control system in a different format.

6. Brakes and slipping clutches:
Brakes and slipping clutches provide protection against overload and prevent the encoder from being damaged by excessive torques.

The following types of brakes are available:

• Mechanical brakes: Block the rotary movement if certain speeds are exceeded.
• Slipping clutches: Compensate for overloads by "slipping" when the torque is too high to protect the encoder.

Use: In applications with high loads or potential overloads, brakes and slipping clutches are used to protect the encoder and minimize downtime.

7. Speed limiters:
Speed limiters protect the encoder by regulating the maximum speed and preventing the encoder from being loaded beyond its operating limits.

Use: Speed limiters are useful in high-speed applications or for machines that experience sudden load changes to prevent damage to the encoder.

8. Special housings and protective covers:
Protective covers and housings protect the encoder from environmental influences such as dust, dirt, water or chemicals. They help to extend the service life of the encoder and increase its reliability.

Application: In harsh environments, such as food processing, mining or chemical plants, special housings are essential to protect the encoder and maintain operation.

9. Encoder software:
Specialized software tools are used to configure encoders, monitor their performance and perform diagnostic functions.

Use: Software is particularly useful in modern, complex applications where the encoder needs to be configured or monitored via digital protocols.

The right accessories for encoders are critical to their performance, longevity and safety.

It ensures that the encoder is correctly installed, protected from environmental influences and mechanically relieved, which guarantees precise and reliable measurement.
