Overview
Assembled by the user in-situ from single-pin elements, the
plug-in connectors in kit form provide a custom solution for every
task.
The basic single-pole connector elements are available in the
colors gray, blue and green-yellow.

Design
Example of a 6-pin connector
The required number of single-connector elements and one
cover are needed for each multi-pole connector. The individual
elements and the cover are simply pushed together and latched
with securing pins.
When assembling connectors for direct installation, an element
with securing pins should be fitted at each end of the connector.
For longer connectors, it is advisable to use an element with se-
curing pins for at least every sixth element.
To ensure that the elements engage securely, the holes must be
burr-free.
