Crimp housing and terminal
PA66 housings list 2–16 positions. The crimp terminal drawing specifies 26–32 AWG. A 16-position housing listing does not establish an available 16-position SMT mating connector.

A1257 connector series
A 1.25 mm single-row wire-to-board connector system with crimp housings and right-angle or vertical SMT board connectors. Select the housing and board connector by their separate position tables.
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.
Right-angle SMT
The PA9T board-connector drawing lists 2–15 positions. Confirm the board footprint and entry clearance for this construction.
Vertical SMT
The PA6T board-connector drawing lists 2–15 positions. Use its specific pad layout and connector dimensions rather than those of the right-angle version.

Before requesting a quote
Confirm your A1257 configuration
Check the housing and SMT board connector position tables separately.
- The housing lists 2–16 positions, while the reviewed right-angle and vertical SMT connectors list 2–15. A 16-position housing does not establish a matching 16-position SMT connector.
- Confirm entry direction, pad layout and clearance using the selected SMT drawing, and specify wire within the listed 26–32 AWG range.
Request housings, terminals and board connectors separately or as a set. Samples are free; typical production MOQ is 1,000–5,000 pieces. Specify your required packaging in the inquiry.
Include the drawing reference, required positions, housing and mating connector, wire size and quantity in your inquiry.
