INFRARED RECEIVER MODULE
MIM-93M2AKF
Description
o
The MIM-93M2AKF is 37.9 KHZ 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.
Features
l Photo detector and preamplifier in one package
l Internal filter for PCM frequency
l High immunity against ambient light
l Improved shielding against electric field disturbance
l 5-Volt supply voltage; low power consumption
l TTL and CMOS compatibility

1-3 H level output voltage
1-4 L level output voltage
2.Items except above mentioned are not inspected particularly , but shall fully satisfy
CAUTION ( When use and storage of this device )
1.Store and use where there is no force causing transformation or change in quality .
2.Store and use where there is no corrosive gas or sea(salt) breeze .
3.Store and use where there is no extreme humidity .
4.Solder the lead-pin within the condition of ratings. After soldering do not add extra force .
5.Do not wash this device . Wipe the stains of diode side with a soft cloth. You can
use the solvent , ethylalcohol or methylalcohol or isupropylene only .
6.To prevent static electricity damage to the Pre-AMP make sure that the human body
, the soldering iron is connected to ground before using .
7.Put decoupling device between Vcc and GND for reduse the noise from power supply line .
8.The performance of remote-control system depends on environments condition and ability
of periferal parts. Customer should evaluate the performance as total system in those conditions
after system up with components such as commander , micon and this receiver module .
