Overview

This document provides technical specifications and connection details for the Orbray ETD10 series optical incremental encoders, specifically models ETD10-2C, ETD10-2D, and ETD10-2E. These encoders are designed for use with the CMS10 motor series, with BMS10 compatibility under development.

Encoder Description

• Type: Optical incremental encoder
• Channels: 2 channels standard; 3 channels optional
• Output Signal: CMOS/TTL compatible

Key Specifications (at 25°C)

Output Signal Characteristics

The output signals correspond to the motor shaft rotating clockwise. The signal cycle is 360°, with each pulse width at 180°. The two channels (A and B) have a phase shift of approximately 90° ± 45°, enabling direction detection. The logic state width is approximately 90° ± 45°.

Electrical Connections

Additional Notes

• Moment of inertia is to be determined (TBD).
• Specifications are subject to change without notice.
• Contact information for Orbray Co., Ltd. is provided for further inquiries.

Summary of Critical Parameters and Best Practices

• Ensure supply voltage remains within 4.5 to 5.5 V for proper operation.
• Maximum operating temperature should not exceed 85°C to maintain device reliability.
• Use CMOS/TTL compatible inputs on the receiving device to match output signals.
• Verify correct wiring according to pin assignments to avoid damage or malfunction.
• Consider the maximum frequency response and resolution when integrating with high-speed motors.
