Product details

Sealed 35-Position Header for Harsh Environments

It features a 0.157" (4.00mm) mating pitch and row spacing, with a shrouded 4-wall design and locking ramp for secure mating under vibration.

Mounting is panel mount with through-hole solder termination — the header passes through the panel and solders to the PCB, with the flange securing it to the panel face. The insulation is gray polybutylene terephthalate (PBT), glass filled, and the contacts are brass with gold-palladium mating finish. All 35 positions are loaded, with contact shape circular male pins.

Comparison with 23-Position Sibling

The 1-776231-4 carries 35 positions versus the 23 positions of the 1-776228-4, both in 3 rows at 4.00mm pitch, with identical sealing, locking ramp, and gold-palladium contacts.
