50-Position AMP-Latch Header for Board-to-Cable Signal Routing
The 1-5499374-0 is a 50-position vertical header from the TE Connectivity AMP-Latch series, designed for board-to-cable/wire applications. It uses a 0.100" (2.54mm) pitch across two rows with a shrouded 4-wall housing and short latch lock/eject hooks to secure the mating cable assembly. Rated at 1 A per contact and 250 VAC, this header is suited for signal-level interconnects in industrial control, data acquisition, and general-purpose electronics where a reliable, keyed connection is needed.
Contact Plating and Temperature Range
Mating contacts are finished with 30.0µin (0.76µm) gold or gold-palladium, while the solder posts receive 100.0µin (2.54µm) tin — the thicker tin post finish withstands wave-solder thermal cycling without dewetting. The header operates from -65°C to 105°C, covering most industrial cabinet and outdoor telecom enclosure environments. The UL94 V-0 housing meets the flame-rating requirement for equipment inside an enclosure.
