Product details

Right-angle panel-mount layout for sealed harnesses

The 4.00mm pitch and 0.157" row spacing set the footprint for the mating receptacle and PCB layout. Its right-angle orientation and combined panel-mount / through-hole termination allow the connector to be anchored to both the enclosure wall and the PCB, handling the mechanical strain of a sealed mate in automotive and industrial environments.

Sealing and retention in the mating interface

The board guide aligns the two halves during assembly, reducing pin damage in a production line or field service setting. Contacts are male pin, circular, made of brass with a Gold-Palladium mating finish — the palladium layer extends mating cycle life beyond standard gold flash, relevant for connectors that see repeated connect/disconnect during vehicle assembly or module swap-out.

Frequently asked questions

Is 1-770669-4 a through-hole header?

Yes, the termination is Solder and the mounting type includes Through Hole, along with Panel Mount and Right Angle. The through-hole tails are soldered into the PCB, while the panel flange secures the connector body to the enclosure.

What is the closest pin-compatible alternative to 1-770669-4?

No pin-compatible alternative is listed in the AMPSEAL series. The 1-770669-4 is a specific 23-position, 3-row, right-angle, sealable header. For a different circuit count or orientation, review other AMPSEAL headers under base number 770669, but verify the footprint and locking ramp compatibility with your mating receptacle.
