20-Pin Quickie™ Header for Board-to-Cable Wiring
The through-hole solder tails anchor the header into the PCB, and the full 4-wall shroud guides the cable plug home without bending pins. Rated UL94 V-0, the glass-filled polyester housing holds up in equipment enclosures that require a flame-rated component.
Comparing 20-Position vs 10-Position Siblings
The 66506-001LF and 66506-001 are 10-position versions of the same header. If the BOM calls for 10 circuits, those are the drop-in; if it calls for 20, the 66506-008LF is the correct pick.
