15-pin (ISO 12098)

Definition: 15-pin (ISO 12098)

What does a 15-pin collector do?

It is impossible to imagine public roads without trucks these days. To keep the roads safe, rules have been drawn up to guarantee traffic safety. An important part of road safety is lighting on vehicles, including trucks and trailers. Trailers alone cannot provide working lights. For this, a connection to a truck is required. Such a connection can be established with a 15-pin (ISO 12098) plug. Through this plug, the truck can transmit electricity to the trailer so that the lights can be activated. The 15-pin plug is just like the 7-pin N and 7-pin S plug, specially made for the truck and trailer sector. These connectors therefore only fit on trucks and trailers and not on trailers or boat trailers.

Different ways of connecting

In order to supply a trailer with electricity, a connection must be established with the truck. This can be done in two different ways. The first way is to use the 15-pole plug. This is quite easy to use with the truck and trailer. The second way is by using two 7-pin connectors These are the 7-pin N and 7-pin S plugs. These plugs must both be connected so that all the lights can work. If only one plug is connected, not all the lighting will work.
