The 0.157\" (4.00 mm) pitch on both mating and row spacing means the board footprint needs 4.00 mm between adjacent pins and 4.00 mm between rows. The panel mount feature adds a secondary retention point for the housing against cable strain. ## Sealing, locking, and temperature range The sealable construction and locking ramp together make this header suitable for environments where moisture, dust, or vibration are present — think underhood automotive or industrial control cabinets. The -40°C to 125°C operating range covers both cold starts and hot engine bays.","metaTitle":"1-776266-1 TE AMPSEAL Header 14 Pos 4mm RA Sealed","metaDescription":"1-776266-1 TE Connectivity AMPSEAL header, 14 positions, 4.00mm pitch, right-angle, sealed, locking ramp.
