BERGSTIK II 86503-452HLF — 52-Position Unshrouded Header
The 0.100" (2.54 mm) pitch is the classic DIP spacing — this header drops onto a perf-board or prototype grid without layout changes. 52 positions loaded all the way across two rows gives 26 pins per side, a dense I/O count for a board-edge or mezzanine interconnect.
The through-hole solder termination with a 0.120" (3.05 mm) post length suits standard 0.062" to 0.093" PCB thickness. Overall contact length is 0.470" (11.94 mm), with a 0.250" (6.35 mm) mating length — enough to engage a standard box receptacle fully.
