CAN-bus installations running at long distances and low speeds can use fairly long stub lines. This allows for a simpler wiring topology where the different nodes can be placed up to 5 meters away from the 'backbone'. Particularly on long distances, this is extra beneficial because the effective length of the CAN-bus can remain shorter, which saves on wiring cost and - more importantly - reduces voltage drops along the line.
To aid such install, we have this field bus distribution box, which allows for up to 6 or 12 cable segments to be joined together. This is done with 5-pole spring terminal connections. The connections are mounted in an IP67/NEMA4X rated polycarbonate enclosure with M16 holes for cable glands. Integrated termination resistor and 2mm multimeter probe-points allow for easy configuration and diagnostic of the network wiring.
