SLX-5MS-MDM Industrial Ethernet Switch

SlimLine Plus Industrial Connectivity with Landline Modem

industrial_ethernet_modemSixnet’s SLX-5MS-MDM couples a 5 port managed industrial Ethernet switch with an integrated landline modem. This powerful combination enables organizations to use a standard telephone line to securely access the network from all remote locations. Designed to be rugged, reliable and secure, our unmanaged SLX switches offer protected circuitry and tough DIN-rail metal packaging to ensure rugged reliability and long-term service in harsh environments. With over 1,000,000 hours MTBF, industrial networks will stay up and running for many years to come.
