Sensor-Technik releases AT8 interface for vehicles

A Sensor-Technik product story
Edited by the Engineeringtalk editorial team Dec 22, 2008

Sensor-Technik UK has introduced Graf-Syteco's AT8 interface, which is ideal as an in-vehicle control panel for CANbus systems.

It combines a high-visibility quarter-VGA colour TFT display with programmable function keys.

This offers simple operator control of the controller area network systems typically employed in vehicle systems such as engine or transmission management or in vehicle-mounted machinery such as lifting gear or agricultural equipment.

The unit can be supplied with one or two CANbus interfaces, allowing a single operator interface to be switched between two separate systems, without interrupting the operation of either network.

The AT8 HMI can withstand the rigours of the commercial vehicle environment.

It is available for dashboard mounting or as a fully enclosed unit.

The front panel is sealed to IP65.

The assembly is qualified to IEC standards for shock, vibration and electromagnetic compatibility, including Level II automotive load dump resistance.

The high-visibility TFT liquid crystal display features 320 x 240 pixel resolution with a screen size of 111 x 83.5mm.

This makes it suitable for displaying text and graphics.

With an optional interface the AT8 can display video, for example from a reversing camera.

The AT8 interface contains eight pushbuttons and a single potentiometer, enabling single-handed control.

All the controls feature halo illumination to enable night-time operation.

The functions of all the controls are freely programmable and the complete HMI can be programmed in C or using optional graphical programming software.

The AT8 HMI runs from a power supply range between 10 and 32V DC (covering both 12 and 24V automotive battery voltages), typically consuming just 600mA from a 24V DC supply.

Internal backup batteries may be specified as an optional extra to maintain control of critical systems should the main vehicle supply fail.
