The Teltonika RUTM52 is a cutting-edge industrial-grade dual-5G router engineered for mission-critical connectivity and demanding IoT applications. Featuring dual 5G modems capable of doubling cellular throughput, it supports both Standalone (SA) and Non-Standalone (NSA) 5G architectures, while maintaining backward compatibility with 4G LTE Cat 20 networks.

Designed for high reliability and flexible deployments, this router incorporates dual SIM slots plus an integrated eSIM supporting multiple profiles to ensure seamless operator switching, failover, and multi-WAN load balancing. Its industrial robustness is complemented by an anodized aluminum enclosure with DIN rail, wall, and flat surface mounting options.

Powered by a MediaTek dual-core 880 MHz CPU with 256 MB DDR3 RAM, the RUTM52 runs on Teltonika's customizable RutOS (OpenWrt-based), offering advanced routing, VPN (WireGuard, IPsec, OpenVPN), and security features. The router supports industrial protocols such as Modbus, DLMS, DNP3, and OPC UA, alongside IoT integrations like MQTT, Azure IoT Hub, and AWS IoT Core.

Connectivity options include five Gigabit Ethernet ports (1 WAN, 4 LAN), dual-band Wi-Fi 5 (802.11ac Wave 2) with MU-MIMO delivering wireless speeds up to 867 Mbps, and multiple antenna connectors including 8 SMA for cellular, 2 RP-SMA for Wi-Fi, and 1 SMA for GNSS (GPS/GLONASS/BeiDou/Galileo/QZSS). The router also has digital input/output ports for simple remote I/O operations.

The device supports a wide power input range of 9–50 VDC with passive PoE on LAN1 and is rated for operation in extreme temperatures from -40°C to 60°C. Comprehensive remote management is enabled through Teltonika RMS with firmware-over-the-air (FOTA), SSH, SNMP, TR-069, and intuitive web UI.

Ideal use cases include industrial automation, telemetry, smart cities, transport, and critical infrastructure where ultra-reliable, high-speed 5G connectivity, extensive protocol support, and flexible deployment options are essential.
