Right-angle sealed header for harsh environments
It uses a 4.00mm pitch (0.157") across three rows with 0.157" row spacing, providing a compact yet robust footprint for sealed harnesses. The sealable feature means the header mates with a sealed AMPSEAL housing to achieve IP-rated environmental protection.
4.00mm pitch and 23-position layout
Compared to the 12-position 1318699-3 which uses 4.20mm pitch and gold-plated contacts, the 770669-1 offers more circuits (23 vs 12) at a slightly tighter pitch (4.00mm vs 4.20mm) with tin plating. The 1318699-3 uses a latch lock instead of a locking ramp and has a 4-row layout vs 3 rows here. The 4-1775099-7 from the ATX series shares the locking ramp and tin plating but uses 4.20mm pitch, 2 rows, and 20 positions. It is not sealed, making the AMPSEAL 770669-1 the better choice for washdown or outdoor applications.
Tin-plated contacts and current derating
The brass contact material with tin plating provides adequate conductivity for signal and low-power circuits.
Packaged in bulk, this header is typically ordered in quantities matching the production run. The base product number 770669 covers the series variants; confirm the full 770669-1 suffix for the 23-position, right-angle, tin-plated version.
