Newly Developed Modules with Lower
Power Consumption and Extra Features.
The IMD Series is comprised of an amplifier and high
performance infrared sensor modules in compact,
hermetically sealed metal can packages.
Power consumption of the module is very low and a Fresnel
lens is included in the module.
Analog & Digital Output Model (IMD-B101-01) and Digital
Output & Brightness Sensor (CdS) Input Model (IMD-B102-
01) are available for different applications.
! Features
1. With the fresnel lens, the sensor is able to detect the
2. The modules have a compact size of 20.3Z12.6Z7.8mm.
3. The modules incorporate an amplifier and a single
4. They have outstanding reliability and EMI characteristics.
5. They have low power consumption.
! Applications
1. Automatic light switches
2. On/off controls for household appliances, industrial
3. Amusement devices (Games, Toys, etc.)
