The IMC-21A series industrial media converters offer a compact and rugged solution for converting 10/100BaseT(X) copper signals to 100BaseFX fiber optics. Designed for harsh industrial environments, they ensure reliable network connectivity under extreme conditions. A variety of models—featuring SC or ST connectors and supporting multi-mode or single-mode fiber—provide flexibility for diverse networking scenarios.

The built-in Link Fault Pass-Through (LFPT) feature improves network reliability by detecting and propagating link failures. DIP switches allow for easy configuration of duplex mode, speed settings, and Auto/Force negotiation. The wide operating temperature range of -40 to 75°C (T models) makes the IMC-21A converters suitable for outdoor and cabinet installations.

Their compact housing and DIN-rail mounting capabilities facilitate easy integration in control panels. With built-in reverse polarity and overload protection, operational safety is further enhanced.
