Everlight Electronics Co., Ltd.
Document No:DMO-0000206
‧ High protection ability against EMI
‧ Circular lens for improved reception characteristics
‧ Available for various carrier frequencies
‧ Min gap length: 12 cycles
‧ Low operating voltage and low power consumption
‧ High immunity against ambient light
‧ Long reception range
‧ High sensitivity
‧ Pb free and RoHS compliant
The IRM-37xxM3 devices are DIP type infrared
receivers which have been developed and designed by
using the latest IC technology.
The PIN diode and preamplifier are assembled onto
a lead frame and molded into a black epoxy package
which operates as an IR filter. The demodulated
output signal can directly be decoded by a
microprocessor.
