INFRARED RECEIVER MODULE
Description
The MIM-R1AA38-1 series are 37.9 KH
Z
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.

NOTE 1. Distance between emitter & detector specifies maximum distance that output wave form satisfies
the standard under the conditions below against the standerd transmitter.
(1)Measuring place ………Indoor without extreme reflection of light.
(2)Ambient light source… Detecting surface illumination shall be 200±50Lux under ordinary
hite fluorescense lamp of no high frequency lighting.
(3)Standard transmitter … Burst wave indicated in Fig 1. of standard transmitter
shall be arranged to 50mVp-p under the measuring circuit specified in Fig 2.
