Industrial IoT hardware, stocked in Riyadh
Technical Fields Trading Co., trading as TEFCO, has supplied vehicle telematics, cold-chain monitoring, industrial connectivity and access-control hardware across Saudi Arabia since 2022.
Beyond supply
Specifying industrial hardware is not the same as buying a consumer gadget. Choosing between a 700mm and 1000mm fuel level sensor, or confirming a data logger meets an audit requirement, takes a conversation.
We provide hardware supply, technical consultancy, technical support, technical manpower and repair services — including support to other tracking companies operating in the Kingdom.
We also pre-configure devices before shipping, so units arrive ready to install rather than ready to set up.
