NR/L2/SIG/30060 Axle Counter Cable

Application

Axle Counter cable is used to connect the various elements of the AzLM Axle Counter System. It is suitable for

installation in trackside cable troughing, buried duct route and installed in open air on the ballast and clipped to

sleepers as required. Quad types XQS and XQZ are used to connect the EAK Junction box or termination to the

EAK (Mushroom) and Multi Twisted pair types XPS and XPZ are used to connect EAK to the ACE (Axle Counter

Evaluator) equipment.
