Pitch and footprint — what the 0.100" spacing buys you
The 1-87232-0: That means your PCB layout stays on a 0.100" grid — no oddball spacing to route around.
Rated 3 A per contact. That's a signal-level current — enough for logic-level power and I/O, not for busbar or motor drive. In a field-service I/O module swapped quarterly, that's decades of reliable connection. Phosphor bronze contact material with gold flash on the post side keeps the solder joint reliable through wave soldering.
