IMC-21 Series
Entry-level industrial 10/100BaseT(X) to 100BaseFX media converters
The IMC-21 industrial media converters are entry-level
10/100BaseT(X) to 100BaseFX media converters designed to provide
reliable and stable operation in harsh industrial environments. The
converters are a cost-effective solution that run on either a 12 to 48
VDC power input and can operate reliably in temperatures ranging
from -10 to 60°C. The rugged hardware design ensures that your
Ethernet equipment can withstand demanding industrial conditions.
The IMC-21 converters are easy to mount on a DIN-Rail or in
distribution boxes.
