The IFM CR3171 is an Ethernet LTE/GNSS radio modem and mobile IoT gateway designed for connecting mobile machines to cloud and remote systems. It combines 4G/LTE, GNSS, WLAN, Bluetooth, Ethernet and CAN communication in one compact unit. Four analogue inputs and a configurable digital output support machine data acquisition and control functions. Its rugged IP6K7 design and -40 to +75 °C operating temperature make it suitable for demanding mobile automation applications.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The CR3171 provides cellular connectivity for machine-to-cloud and remote communication applications. It supports multiple 2G, 3G and 4G/LTE frequency bands, allowing it to be deployed across different mobile network environments. An integrated eSIM simplifies mobile network connectivity.
The device provides an M12 D-coded Ethernet interface together with multiple CAN connections. This allows machine controllers, sensors and other electronic systems to exchange operational information with remote applications.
Integrated GNSS enables positioning and location-related applications, while WLAN and Bluetooth provide additional local communication options. The device can therefore function as a flexible communication hub for connected mobile machinery.
The CR3171 operates from 6...36 V DC and is designed for harsh mobile-machine environments. With IP6K7 protection when suitable connectors or protective caps are installed, it provides strong resistance against environmental exposure.
