Our Products

x4 Automotive has been responsible for the launch of many pioneering products, all of which have been created after extensive consultations with our clients to address a specific customer need (or needs).


Automotive Ethernet Translator (AETM) Module

The AETM is designed to convert Ethernet signals between a vehicle’s ECU and a PC to support the updating of software modules (re-flashing) or to be used in any test simulation environment.

Key Features:

  • Rugged enclosure

  • Converts between 100/100Base-T1 & 100/100Base-Tx


  • Temperature range: -20°C to +70°C

  • Supply voltage range (normal operating): 9Vdc to 16Vdc

  • Dimensions (H x W x D): 33mm x 62mm x 96mm

  • Data rate: 100 Mbit/s guaranteed

  • Current consumption: <100mA

  • Weight: 96g

  • IP rating: 40


Transit Relay Extender Box (TREB) – Manufacturing Aid

We developed our TREB module for use in Jaguar Land Rover (JLR) assembly plants. JLR stipulated that the product needed to:

  • Keep the vehicle connected to the battery during manufacturing;

  • Stop false flagging diagnostic trouble codes during the manufacturing process;

  • Allow the vehicle battery to charge for 3600 seconds on every umbilical connection;

  • Be robust enough to survive a 1.5m drop test;

  • Boast good connectivity robustness;

They also wanted to ensure that one side of the terminations must have 50mm of exposed cable, ready to be terminated on site.


INTERFACE BOARD – System Testing Aid

Our interface board was again created for Jaguar Land Rover (JLR). The product was produced in a relatively small batch, and the project included:

  • Incorporation of SMT sockets

  • PCB assembly – through-hole soldering

  • The final assembly of the switches and display unit

  • A functional test
