The P11159-201AS is an optical encoder module integrating a red LED and a 4-element photodiode-based photo IC for detecting displacement or rotation via 2-phase TTL-compatible digital output. The module operates with a supply voltage of 3.0 to 7.0 V, draws 6.0 to 10 mA, and delivers a maximum response frequency of 50 kHz. It produces phase A and phase B outputs with a typical phase difference of 90 degrees and a duty ratio of 50%. The device has a forward LED voltage of 1.9 V at 10 mA and a peak emission wavelength of 650 nm. It is rated for operation from -40 to +85 °C and supports lead-free flow soldering. The package is small, designed for easy alignment with positioning pins.
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-element 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.
