What This Housing Does in the Assembly
The housing ships empty. Confirm the terminal part number with the housing before committing the BOM.
Polarization and Keying
The SL-156 receptacle housing is polarized — the cavity shape and the board latch orientation prevent reverse mating. The single-row layout with the latch on one side means the housing can only be inserted onto the header one way. No separate keying plug is needed for basic orientation.
