Sontheim provides a broad range of CAN interfaces for deployment in various industries, environments and use-cases. Each interface uses the same multi-threaded API (application programming interface) allowing simultaneous access of numerous threads from application to network, an easy exchange of devices and a combination of interfaces. The Sontheim software tools consist of many components for field-bus configuration, control and analytics.


This piece of interface technology offers a CAN channel along with an EIA-232- (RS-232)-interface and USB for connecting to a laptop or desktop PC. It is the latest one in our portfolio and benefits from a powerful 32-bit microprocessor. Housing, cables and plugs have been designed with regards to a most resource- and cost-saving setup.


The CANUSB is a CAN-to-USB interface that is used in mobile applications on notebooks and desktop PCs. As the CANUSB is built into a massive aluminum case with a size of 100 mm x 57 mm x 32 mm, it can also be used in rough environments.

The field-proven interface holds several technical attributes for a maximum of usability. Its optional features like error-frame detection and analog level measurement for the physical CAN networks level make it a reliable and easy-to-use interface for various applications in the fields of automation and automotive. It provides two opto-isolated CAN channels with a data transmission of up to 1 Mbit/s. on both channels. The device is available in different versions, e.g. only one single CAN-channel and less diagnostic functions.


For standardized applications with only one CAN channel, the Sontheim Industrie Elektronik GmbH supplies the CANUSBlight with one opto-isolated CAN channel. This CAN-to-USB interface is built into a compact synthetic case with a size of only 52 mm x 3 6mm x 21 mm and even more suitable for a mobile use. All mobil interfaces can be used with Windows versions like 2000, XP Embedded and Professional, up to Vista and Windows 7.


The PowerCAN-PCI is a CAN interface and controller card for the PCI bus which provides up to three opto-isolated CAN channels to the user. Each channel has a maximum transfer speed of 1 Mbit/s. The PowerCAN-PCI is used as a controller card in complex machines. Its C167 micro-controller provides high computing power, which is topped up by 16 KiB DPRAM, 256 KiB Flash and 256 KiB RAM.

As a producer of industrial PCs, Sontheim also offers the PowerCAN card as a CPCI and a PC104+ version for embedded purposes with up to two opto-isolated CAN channels.


The next generation of the CAN controller family has several new hardware features for increased performance. It contains a 32-bit Coldfire microprocessor as well as 32 KiB DPRAM, 2 MiB Flash and 8 MiB RAM. There are two opto-isolated CAN channels and additional diagnostic functions integrated like level measurement and an error frame detection that allows seeing the relation between error frame and timestamp. The PowerCAN-PCI V2 is available as a PCI or PCI104 version.

The firmware update is handled directly via USB or PCI interface with a free software tool to keep the CANUSB features up-to-date. Moreover, the hot plug-and-play system enables an even faster and more efficient application without the need for restarting the computer.
