Rugged industrial wired router with VPN, firewall, and protocol gateway for IIoT

RAM-6021 Industrial IP67 Wired Router

Item number RAM-6021M12

The RAM-6021M12 Industrial IP67 Wired Router is a flexible, connects and secures local industrial networks to wider area networks (LAN-to-LAN or LAN-to-WAN) using M12-style connectors. It combines the functions of a router, firewall, VPN gateway, and protocol converter into a single, rugged device.


Features and benefits

  • M12 Connectors for High Vibration

    Utilizes secure, lockable M12 connectors for all Ethernet ports. This design ensures connection integrity against extreme shock and vibration, ideal for rail and transit use.

  • IP67 Rated for Dust and Water

    Housed in a fully sealed enclosure with an IP67 rating. Provides comprehensive protection against dust ingress and temporary water immersion in harsh outdoor environments.

  • Extreme Temp Networking

    Functions as a secure router with an extended operating range of -40 °C to 80 °C. Ensures reliable, high-speed routing in non-climate-controlled locations.

  • 5-Port 10/100 Ethernet Switch

    Provides five M12 Ethernet ports (one configurable as WAN/LAN). Functions as an integrated switch/router to simplify network architecture and reduce component count.

  • Integrated Security via Firewall/VPN

    Features a built-in Stateful Inspection Firewall and supports up to 25 IPsec/SSL VPN tunnels. Protects critical systems and enables secure remote monitoring access.

  • Protocol Gateway for Field Devices

    Includes support for protocols like Modbus and DNP3. Allows legacy and multi-vendor industrial devices to communicate seamlessly over the modern network.

  • Ruggedized Transportation Ready

    Certified for extreme environmental conditions including shock and vibration standards. Perfect for deployment on trains, buses, and heavy-duty mobile equipment.

  • Connect Legacy Serial Devices

    Equipped with a Serial (RS-232) port, allowing for Serial-to-IP conversion. Provides a robust pathway for integrating older PLCs and devices into the secure IP network.
