Teltonika PR4MK04K 4-Pin Power Plug with Contact Terminals for RUT and TSW Devices

Sometimes no pre-made cable fits the installation: the run is an unusual length, the panel standard dictates a specific wire gauge and color code, or power must come from a source no stock lead anticipates. The PR4MK04K exists for exactly these builds. It is the 4-pin power connector Teltonika devices use, supplied as a kit with contact terminals so an installer can terminate custom wiring and assemble a plug that mates with the device like the factory part it is.

The workflow is familiar to anyone who builds panel wiring: crimp the contact terminals onto your conductors, insert them into the plug housing in the pin order your device's manual specifies, and connect. Because all four positions are available, the finished lead can carry the router's I/O lines alongside power — ignition sense in a vehicle, an alarm contact in a cabinet — through one connector.

Compatibility spans the devices sharing this power interface: RUT240, RUT300, RUT360, RUT950 and RUT955 routers, RUTX08, RUTX10, RUTX11 and RUTX12, the TSW100 and TSW110 switches, and the TCR100. That breadth makes the kit a standard stock item for integrators — one bag of connectors covers nearly every Teltonika build on the bench.

Two cautions from the field: always verify the pinout for the specific model before energizing, since pin assignments are model-documented, and use a proper crimp tool rather than pliers — a cold crimp joint is the kind of fault that surfaces six months later as an intermittent reboot.
