Product details

Sealed 35-position header for harsh environments

Its sealed construction and mounting flange make it suitable for automotive and industrial environments where moisture and contaminants are present.

Key features for fit and reliability

The 4-wall shrouding and locking ramp fastening provide positive retention and misalignment protection during mating, critical for vibration-prone installations. The header is panel-mountable with a mounting flange, and the through-hole solder termination secures it to the PCB while the flange takes the cable strain off the solder joints.
