What is the CE-65-M encoder
The TR Electronic CE-65-M is an absolute rotary encoder designed for industrial automation. It measures angular position and motion, sending precise data to controllers that follow the DIN 19258 standard. This hardware component is critical for machinery that requires accurate feedback on shaft rotation, such as robotics, printing presses, and automated assembly lines.
It is important to distinguish this industrial device from other entities sharing the "CE 65" name. The CE-65-M is not a financial exam, a certification program, or related to California Proposition 65 safety regulations. It is a physical sensor built for harsh environments, engineered to withstand vibration and shock while maintaining measurement integrity.
For technical specifications and wiring diagrams, refer to the official TR Electronic documentation. Understanding the encoder's role in your specific control loop ensures you select the correct model and interface for your application.
Key technical specifications
Engineers selecting the TR Electronic CE-65-M encoder need precise data to ensure compatibility with existing control systems. The encoder captures angular motion and conditions measuring data for controllers that adhere to the DIN 19258 standard. This section outlines the hard specifications required for integration, focusing on resolution, interface types, power requirements, and physical dimensions.
The CE-65-M is available in two primary interface variants: Interbus-S and Profibus-DP. Both support absolute position tracking, meaning the encoder retains position data even after a power cycle. This eliminates the need for homing sequences, which is critical for safety-critical applications and machinery where downtime is costly. The choice between Interbus-S and Profibus-DP depends on the specific fieldbus architecture of your PLC or controller.
Power requirements are standardized across variants, operating on a DC voltage range of 11 to 27 V. Current consumption is typically around 350 mA. The physical design is robust, built for industrial environments, with a standard shaft diameter that fits common mounting configurations. Always verify the specific shaft and flange dimensions against your mechanical assembly drawings before procurement.
The following table compares the key technical specifications for the two main interface variants of the CE-65-M encoder. Use this data to select the correct model for your system's communication protocol.
| Specification | Interbus-S Variant | Profibus-DP Variant |
|---|---|---|
| Interface Protocol | Interbus-S | Profibus-DP |
| Supply Voltage | 11–27 V DC | 11–27 V DC |
| Current Consumption | ~350 mA | ~350 mA |
| Position Data | Absolute | Absolute |
| Standard Compliance | DIN 19258 | DIN 19258 |

This document provides the definitive electrical and mechanical drawings required for safe installation. Always consult the primary manufacturer documentation to avoid wiring errors that could damage the encoder or the connected controller.
Common industrial applications
The TR Electronic CE-65-M encoder is designed for environments where precise angular measurement and robust data conditioning are required. Its primary function is to acquire angular motion and send conditioned data to controllers that adhere to the DIN 19258 standard [[src-serp-1]]. This makes it a reliable component in systems that demand high accuracy and reliability.
Machine Tools
In machine tools, the CE-65-M is often used to monitor spindle position and feed axis movement. The encoder’s ability to provide precise angular data helps maintain tight tolerances during cutting and milling operations. This precision is critical for ensuring that machined parts meet exact specifications.
Robotics
Robotic systems rely on accurate feedback for smooth and controlled movement. The CE-65-M encoder provides this feedback by tracking the angular position of robotic joints. This allows robots to perform repetitive tasks with high repeatability, which is essential in manufacturing and assembly lines.
Packaging Machinery
Packaging equipment requires precise control over conveyor speeds and product positioning. The CE-65-M encoder helps manage these variables by providing real-time data on the position and speed of moving parts. This ensures that products are packaged correctly and efficiently, reducing waste and downtime.
How to install and wire the CE 65
Installing the TR Electronic CE-65-M encoder requires careful attention to mechanical alignment and electrical safety. Because this device handles industrial signals for Interbus and Profibus networks, incorrect wiring can damage the controller or the encoder itself. Follow this sequence to mount the unit and connect the cables correctly.
1. Prepare the mounting surface
Ensure the mounting bracket or shaft is clean and free of debris. The CE-65-M must be secured firmly to prevent vibration-induced errors. Use the specified mounting holes and torque the screws to the manufacturer’s recommendation. Avoid overtightening, which can distort the housing and affect internal bearings.
2. Align the encoder shaft
Connect the encoder to the rotating shaft using a flexible coupling. Misalignment is the leading cause of premature bearing failure. Check both parallel and angular alignment before tightening the coupling set screws. The shaft must rotate freely without binding or excessive play.
3. Verify power and safety
Before connecting any wires, ensure the control cabinet power is locked out and tagged out. Verify that the supply voltage matches the encoder’s rating (typically 10-30 VDC). Use a multimeter to confirm there is no residual voltage on the lines. This step prevents accidental short circuits during wiring.
4. Connect the signal cables
Refer to the pinout diagram in the TR Electronic datasheet for your specific variant (Interbus or Profibus). Connect the power lines first, followed by the data lines. Shielded cables are required for industrial environments to prevent electromagnetic interference. Terminate the shield at one end only, usually at the encoder housing, to avoid ground loops.
5. Secure and test
Route the cables away from high-voltage lines and moving parts. Use cable ties or conduits to protect the wiring. Once everything is secured, restore power and check the LED indicators for proper operation. Verify the controller receives valid position data before releasing the machine for production.

Where to buy CE-65-M encoders
You can source the TR Electronic CE-65-M encoder through authorized industrial distributors, specialized surplus dealers, or major online marketplaces. The right channel depends on your timeline and whether you need a certified new unit or are open to inspected used inventory.
For immediate availability and buyer protection, Amazon and eBay are common entry points. Amazon often lists new units with clear return policies, while eBay offers a wider range of new and used options from verified sellers. Always check the part number (such as 110-00226 or 110-00888) to ensure compatibility with your specific Profibus-DP or analog application.
Specialized industrial surplus sites like Maschinenteil24 provide another reliable option. These dealers often stock used encoders that have been tested and come with short-term warranties, which can be a cost-effective solution for maintenance repairs where downtime is critical.
Verify authenticity and condition
Counterfeit encoders are a risk when buying from non-authorized third-party sellers. To avoid this, prioritize sellers with high feedback scores and clear return policies. When purchasing used units, request photos of the label and connector pins to verify there is no corrosion or physical damage.
