Housing constructions
The drawings show PA66 housing profiles with staggered contacts and a tin-plated phosphor-bronze crimp terminal. Conflicting row headings and repeated position labels prevent a reliable universal housing range.

Connector construction
Compare configuration options
Select the housing, contacts and mating connector together. The available circuit counts and materials depend on the specific drawing, rather than one range covering every variant.
SMT board profiles
The board drawings specify PA6T, gold-flash phosphor-bronze contacts and tin-plated phosphor-bronze solder tabs. The upright profile tables list 21 and 31 positions; a separate right-angle profile lists 21, 31 and 41. Confirm the exact drawing and contact arrangement.
