CAN splitter box saves space

As the suite of on-board electronics in a vehicle has continued to grow, the physical layer in cabling and interfacing has become a restraint. With this in mind, a CAN splitter box (CompactCAN) has been developed by TE Connectivity Deutsch (UK).

THE SPLITTER BOX INCREASES THE DENSITY of nodes and reduces the size of the box in some cases by 75 %. With between 2 and 14 nodes, this box gives the system designer flexibility in compact spaces without sacrificing performance. With its reliability of individual cables it eliminates daisy chaining, and with up to 10 nodes per box it causes less cabling. The box is suitable for the CAN networks CANopen, J1939, Devicenet, and MilCAN. MilCAN is a deterministic protocol that can be applied to CAN technology as specified by ISO 11898. It was initially developed for the Military Land Systems domain, but may be applied wherever there is a requirement for deterministic data transfer. The box also features a dual bus for redundancy and each node only requires one cable.

The splitter box consists of a metal alloy box with black zinc nickel finish for durability in hostile conditions, and an EMI gasket for shielding integrity. As connectors it offers an MC 9 way connector, size 24 crimp contacts, and size 22 non-removable contacts. It needs a maximum of 600 V, 3 A, and 267 Ω. The bus length lies at 320 mm, and the internal stub length at 30 mm. No electrical or mechanical defects occur after 500 cycles, it has a temperature range of -55 °C to +175 °C, and IP67 protection level.
