Product Overview

The document describes the Orbray ETD16-2D/E/F series optical incremental encoders designed for motor feedback applications. These encoders provide 2 or 3 channel outputs and are compatible with the CMS16 series motors, with BMS16 compatibility under development.

Specifications

• Encoder Type: Optical incremental
• Output Signal: CMOS/TTL compatible
• Number of Channels: 2 or 3 (optional third channel Z)
• Resolution Options: 213, 512, or 1024 pulses per revolution
• Maximum Frequency Response: 110 kHz to 220 kHz depending on resolution
• Supply Voltage (Vcc): 4.5 to 5.5 V DC
• Typical Supply Current: 20 mA
• Output Voltage Levels: High level max 2.4 V (Voc), Low level approx 0.4 V
• Output Current per Channel: 1.5 mA
• Rise and Fall Times: 100 ns each (with load RL=2.7 kΩ and CL=25 pF)
• Operating Temperature Range: 20 to 85 °C
• Storage Temperature Range: 20 to 85 °C
• Maximum Speed: 25,000 rpm
• Inertia: To be determined (TBD)

Output Signal Characteristics

The encoder outputs incremental signals with a 90° phase shift between channels A and B, enabling direction detection. The logic state width is approximately 90° ± 45°. The output signals correspond to motor shaft clockwise rotation.

Electrical Connections

• Pin 1: MOTOR+ (Motor positive terminal)
• Pin 2: Vcc (4.5 to 5.5 V DC supply)
• Pin 3: Channel A output (CMOS/TTL compatible)
• Pin 4: Channel B output (CMOS/TTL compatible)
• Pin 5: NC or Channel Z output (optional third channel)
• Pin 6: GND (Ground)
• Pin 7: MOTOR- (Motor negative terminal)
