What This Header Does — 5-Position Friction-Lock on 0.100" Pitch
The 1718560105: This is a 5-position Molex KK254 header with a single-wall shroud and a friction lock that clicks onto the mating receptacle housing — no secondary latch needed for moderate vibration environments. Rated for 500VAC / 600VDC, the voltage ceiling is generous for signal-level and low-power circuits inside a cabinet, but the 80°C operating limit means it stays out of hot zones.
Peer Comparison — 1718560105 vs 1718560104 (4-Position)
The only difference between the 5-position 1718560105 and the 4-position 1718560104 is the circuit count — 5 positions vs 4. All other specs (pitch, plating, lock, dimensions, ratings) are identical.
