Unity Opto Technology MIM-0KM2AKL Datasheet

INFRARED RECEIVER MODULE MIM-0KM2AKL

Description

The MIM-0KM2AKL SERIES is miniaturized infrared
receivers for remote control and other appplications
requiring improved ambient light rejection.
The separate PIN diode and preamplifier IC are assembled
on a single leadframe.
The epoxy package contains a special IR filter.
This module has excellent performance even in disturbed
ambient light applications and provides protection against
uncontrolled output pulses.
