20-Position Single-Row Board-to-Board Receptacle
The mating interface carries 30 µinch gold or GXT™ over phosphor bronze contacts.
Housing Material and Temperature Range
This makes the 68685-320LF suitable for equipment inside enclosures requiring flame-rated materials, as well as applications exposed to thermal cycling from automotive engine compartments or outdoor telecom cabinets.
Position Count vs. 16-Position Sibling
The 68685-320LF offers 20 positions, while the 68685-316LF provides 16 positions in the same single-row, 0.100" pitch, through-hole footprint. All other specs — voltage rating, contact plating, housing material, and temperature range — are identical. The choice comes down to the number of signal or power lines the board design needs to route through a single connector.
