The 77317-803-46LF: The breakaway feature lets you snap the header to a custom pin count during assembly, giving flexibility for prototypes or production runs where the full 46 positions aren't needed. The push-pull fastening type means it's a friction-fit mate with no locking latch — fine for low-vibration environments where the connector isn't subject to mechanical shock.
Termination is solder to through-hole vias on the PCB. The post length is 0.100" (2.54mm) — typical for a standard 1.6mm-thick board with the header sitting flush against the solder side. The insulation height is 0.190" (4.83mm) above the board surface, leaving clearance for components under the header body.
The base product number is 77317, which covers the full BERGSTIK® header family. The -803-46LF suffix specifies the 46-position, right-angle, gold-plated variant.
The wide span means the connector can handle thermal cycling in outdoor cabinets or near heat sources without degrading the contact interface. The part is RoHS-compliant per the 'LF' suffix in the order code, which indicates lead-free and RoHS-compliant construction.
