One of the most important features, however, is the closed design of the sleeve which makes it absolutely safe against flux wicking during the soldering process.

The insulators are thus easy Insertion diameter and contact point of the receptacles may vary to cut to any length in most cases without any loss of contact. depending on contact type.
