AEDR-8400 Series
Reflective Surface Mount Optical Encoder
Data Sheet
Description
The AEDR-8400 encoder is the smallest optical encoder
employing reflective technology for motion control
purposes. The encoder houses an LED light source and a
photo-detecting circuitry in a single package.
The AEDR-8400 encoder offers two-channel quadrature
digital outputs. Being TTL compatible, the outputs of the
AEDR-8400 encoder can be interfaced directly with most
of the signal processing circuitries. Hence the encoder
provides great design-in flexibility and easy integration
into existing systems.
Features
• Reflective technology
• Surface mount leadless package
• Two channel quadrature digital outputs for direction
sensing

LED Current Limiting Resistor
A resistor to limit current to the LED is required. The recommended value is 121Ω (±1%) for 254 LPI and 255Ω (±1%)
for 318 LPI. The resistor should be placed in series between the 2.8 V supply and pin 1 of the device (VLED). This will
result in an LED current of approximately 6mA.
Moisture Sensitive Level
The AEDR-8400 is specified to moisture sensitive level (MSL) 3.
