Encoder module
P11159-201AS
Small package and high resolution encoder
module
The P11159-201AS is an optical encoder module that consists of a photo IC and red LED. The photo IC incorporates a 4-el-
ement photodiode and a 2-phase digital signal output circuit. When using 0.2 mm pitch slits, the P11159-201AS produces a
2-phase digital signal output matching the slit movement.
Features
High resolution: 0.05 mm (2-phase output)
Positioning pin for easy alignment
Small package
Suitable for lead-free ow soldering

*1: Forward current decreases at a rate of 0.5 mA/°C above Ta=55 °C
*2: Power dissipation decreases at a rate of 3.1 mW/°C above Ta=25 °C
Note: The P11159-201AS is not suitable for reow soldering.
Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.

*3: Measured when recommended slits are used in specied position
Response frequency f is the reciprocal of the time required to move one pitch.
*4: Maximum frequency at which no error occurs in the output transition sequence (See operation timing diagram.)
Note: Connect a capacitor of 0.1 μF or more between Vcc and GND terminal.
