Tin-Plated Contacts and 40 V Rating
The 40 V rating covers low-voltage signal and control circuits common in industrial I/O and sensor interfaces.
The base product number is 280523; the -1 suffix denotes the specific configuration (12 positions, right-angle, detent lock, tin plating).
Comparing 12-Position and 8-Position Siblings
The closest functional peer within the same series is the 280380-1, an 8-position version with identical pitch, plating, mounting, and locking. For a BOM that needs fewer circuits, the 8-position sibling is a drop-in fit on the same footprint pattern.
