ComNet CNFE2MC2C ComFit Ethernet Media Converter with Contact Closure Relay, 10/100Mbps

Deliver reliable fiber connectivity and remote relay control for security and surveillance systems with the ComNet CNFE2MC2C ComFit Ethernet media converter. This compact media converter converts 10/100 Mbps copper Ethernet to optical fiber while carrying two bi-directional contact-closure signals—ideal for alarms, door control, I/O monitoring and other security integrations. Use industry-standard SFP modules (sold separately) to select single-mode or multimode fiber and the connector type and distance that match each site.

Designed for installers and integrators, the CNFE2MC2C auto-negotiates the RJ45 electrical port to 10 or 100 Mbps and provides robust 100 Mbps fiber performance without manual adjustments. The environmentally hardened ComFit housing supports DIN-rail or rack mounting and meets NEMA TS-level requirements for traffic and industrial deployments, helping minimize downtime in harsh conditions. With plug-and-play operation, low 8W power consumption and lifetime limited warranty, this ComNet media converter reduces installation time and long-term support costs. Ideal for networked video surveillance, remote monitoring and access control applications—add the CNFE2MC2C to your next security or monitoring deployment for dependable fiber Ethernet extension.
