1. Introduction
This manual provides essential information for the safe and effective installation, operation, and maintenance of the ELCO EB50P8 Series Rotary Encoders. These encoders are precision devices designed to convert rotational motion into electrical signals, commonly used in industrial automation for position feedback, speed measurement, and direction sensing. Please read this manual thoroughly before using the product.

2. Setup
Proper installation and wiring are crucial for the correct functioning of the rotary encoder. Ensure all power is disconnected before proceeding with installation.
2.1 Mounting
The ELCO EB50P8 series encoders typically feature a hook-type fixed mounting. Secure the encoder firmly to the desired application point, ensuring the shaft is properly aligned with the rotating component to be monitored. Avoid excessive force during mounting to prevent damage to the encoder or its internal components.
2.2 Wiring Connections
Refer to the wiring diagram below for correct electrical connections. The encoder operates on a voltage range of 5-30Vdc. Incorrect wiring can lead to damage to the encoder or the connected equipment.

| Pin/Signal | Wire Color |
|---|---|
| OV (Ground) | White |
| +UB (Power Supply) | Brown |
| A- | Yellow |
| A+ | Green |
| B- | Pink |
| B+ | Gray |
| 0+ | Blue |
| 0- | Red |
3. Operating Instructions
Once properly installed and wired, the ELCO EB50P8 rotary encoder will generate electrical pulses corresponding to its rotational movement. These pulses can be read by a compatible controller (e.g., PLC, microcontroller) to determine position, speed, or direction.
- Power On: Apply the specified DC voltage (5-30Vdc) to the +UB and OV terminals.
- Signal Output: The A+, A-, B+, B-, 0+, 0- terminals provide the encoder's output signals. The specific signal type (e.g., Push-Pull, Open Collector, Line Driver) depends on the encoder variant. Consult your system's requirements for signal interpretation.
- Rotation: As the encoder shaft rotates, it generates a sequence of pulses on the A and B channels. The phase difference between A and B signals indicates the direction of rotation. The Z (0+ and 0-) channel provides a single pulse per revolution for reference.
4. Maintenance
The ELCO EB50P8 series rotary encoders are designed for durability and require minimal maintenance. However, adhering to the following guidelines can prolong their lifespan and ensure reliable performance:
- Keep Clean: Regularly clean the exterior of the encoder to prevent dust, dirt, or debris from accumulating, especially around the shaft and cable entry points. Use a soft, dry cloth. Avoid harsh chemicals or abrasive materials.
- Inspect Cables: Periodically check the connecting cables for any signs of wear, fraying, or damage. Ensure connections are secure.
- Environmental Conditions: Ensure the encoder operates within its specified environmental limits (temperature, humidity, vibration) to prevent premature failure.
- Avoid Mechanical Stress: Do not apply excessive radial or axial load to the encoder shaft. Ensure proper alignment during installation.
5. Troubleshooting
If the encoder is not functioning as expected, consider the following troubleshooting steps:
- No Output Signal:
- Verify power supply (5-30Vdc) is correctly connected and within the specified range.
- Check all wiring connections against the diagram (Table 1) for correctness and secure contact.
- Ensure the encoder shaft is rotating.
- Inaccurate Readings:
- Check for mechanical slippage between the encoder shaft and the rotating component.
- Inspect for excessive vibration or shock that might affect signal integrity.
- Ensure the controller reading the signals is configured correctly for the encoder's resolution and signal type.
- Intermittent Signals:
- Look for loose connections or damaged cables.
- Check for electromagnetic interference (EMI) from nearby equipment. Use shielded cables if necessary.
If problems persist after these checks, contact technical support.
