1. Introduction and Overview
The Autonics ENC-1-1-T-24 is an incremental wheel type rotary encoder designed for precise measurement of length or speed of continuously moving objects. This encoder provides an output waveform proportional to the measured distance, calibrated to international measurement units (meters or inches). It operates on a 12-24VDC power supply and features a totem pole output.
This manual provides essential information for the safe and effective installation, operation, and maintenance of your ENC-1-1-T-24 encoder.

5. Setup and Installation
5.1 Mounting
Mount the encoder securely to a stable surface, ensuring that the wheels make firm and consistent contact with the object to be measured. The mounting position should allow for proper alignment and prevent slippage during operation. Consider the direction of movement and the desired measurement axis when positioning the encoder.
5.2 Wiring
The ENC-1-1-T-24 features a totem pole output. Refer to the following general wiring guidelines. Always consult the specific wiring diagram provided with your unit for precise connections, as color codes may vary.
| Wire Color (Typical) | Function | Description |
|---|---|---|
| Brown | +V (Power Supply) | Connect to 12-24VDC power source. |
| Blue | 0V (Ground) | Connect to common ground. |
| Black | Output A | Phase A signal output. |
| White | Output B | Phase B signal output (90° phase shift from A). |
| Orange | Output Z (Index) | Reference pulse output (one pulse per revolution). |
Important: Ensure all connections are secure and insulated to prevent short circuits. Incorrect wiring can damage the encoder or connected equipment.
6. Operating Instructions
Once properly installed and wired, the ENC-1-1-T-24 encoder will generate pulse signals corresponding to the movement of the object it is measuring. These pulses can be fed into a counter, PLC, or other control system to determine length, speed, or position.
- Direction Detection: The phase difference between Output A and Output B allows for detection of the direction of rotation or movement.
- Pulse per Millimeter: The encoder generates 1 pulse for every 1mm of linear movement of the measured surface.
- Speed Measurement: By counting pulses over a specific time interval, the speed of the object can be calculated.
- Length Measurement: By accumulating the total number of pulses, the total length of the object can be determined.
Refer to the documentation of your connected control system (e.g., PLC, counter) for specific programming and configuration details to interpret the encoder's output signals.
7. Maintenance
The Autonics ENC-1-1-T-24 encoder is designed for reliable operation with minimal maintenance. However, periodic checks can help ensure its longevity and accuracy.
- Cleaning: Regularly clean the encoder wheels and the surface they contact to prevent accumulation of dust, debris, or oil, which can affect measurement accuracy. Use a soft, dry cloth. Do not use harsh chemicals or abrasive materials.
- Inspection: Periodically inspect the mounting for tightness and ensure the wheels are making proper contact with the measured surface. Check the cable for any signs of wear or damage.
- Environment: Ensure the operating environment remains within the specified conditions (temperature, humidity, vibration).
8. Troubleshooting
If you encounter issues with your ENC-1-1-T-24 encoder, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output signal | No power or incorrect wiring. | Check power supply connections (+V and 0V). Verify wiring against the diagram. |
| Inaccurate measurement | Slippage of wheels, debris on wheels/surface, or incorrect mounting pressure. | Ensure firm contact between wheels and surface. Clean wheels and surface. Adjust mounting pressure if possible. |
| Intermittent signal | Loose connections, damaged cable, or electrical noise. | Check all wiring connections for tightness. Inspect cable for damage. Consider shielding or grounding improvements if electrical noise is suspected. |
| Incorrect direction detection | Output A and B signals are swapped or misinterpreted by the control system. | Verify A and B wiring. Check control system's configuration for quadrature decoding. |
If the problem persists after attempting these solutions, contact Autonics technical support or your local distributor for further assistance.
