Description
Robust adapter cable for directly connecting up to four CAN buses via a single DB25 connector. The A040 distributes the signals to four DB9 connectors, providing a compact and mechanically stable connection solution for field devices, data loggers, and gateways. Technical specifications: DB25 (female) to 4 × DB9 (male), cable length 20 cm, operating temperature −20 °C to +80 °C, weight approx. 210 g. Ideal for connecting CAN gateways and streaming interfaces, as well as for parallel connection of multiple CAN loggers.

The A040 DB25-to-4xDB9 adapter cable is a space-saving and robust solution for distributing multiple CAN interfaces via a single DB25 connector. It cleanly transmits CAN High/CAN Low/Ground to four separate DB9 connectors, enabling the parallel operation of devices such as gateways, streaming interfaces, or CAN loggers. With a cable length of 20 cm, the A040 is particularly suitable for compact installations and test setups where short connection paths are crucial. Its temperature range of -20 °C to +80 °C and robust black housing ensure reliable operation even in harsh environments. Typical applications include splitting a primary CAN port for logging and diagnostics, connecting multiple measuring devices to a CANmod router, or using it with CAN streamers and external loggers. The fixed pin assignment prevents incorrect connections and simplifies integration into existing test and measurement setups.
