It uses a 0.071" (1.80mm) pitch — tight enough to save board space but wide enough that 20-24 AWG wire can be terminated without forcing a tight bend radius.
Six positions in one row — match your circuit count exactly; there's no unused cavity to seal. The 1.80mm pitch means the matching header footprint is tight: confirm your PCB layout can route a trace between pads at this spacing before committing. Free-hanging (in-line) mount means this housing is meant to be spliced into a harness, not bolted to a panel — it floats with the wire bundle, which helps absorb vibration. That covers cold storage and warm industrial cabinets without the plastic getting brittle or softening. Natural colour — no dye means no pigment-related brittleness in the latch arm.
Mating and Termination — What Crosses Into the Harness You've Got
This receptacle mates with the matching CONNTAK50 plug header (male pin housing) from the same 208037 series — same 1.80mm pitch, same 6-circuit count, same latch lock interface. On the termination side, it accepts crimp female socket contacts. The crimp termination means you can re-pin it on site with a basic ratchet crimper; no soldering iron needed.
