The TE 5787422-1 is a 5-position, single-row header with male blades, designed as a 12.0V battery connector. It carries a 7 A per-contact current rating at 12 V, which means each blade is sized for the main power feed in a low-voltage DC system — not a signal line.
The 7 A per-contact rating defines the maximum continuous current each blade can carry before the temperature rise exceeds the LCP housing limit. The Right Hand Keying prevents accidental mating with a left-hand keyed receptacle, which is a common mis-mating trap in multi-connector battery harnesses. The -30°C to 70°C operating range covers indoor and sheltered outdoor environments, but the 70°C ceiling means it should not be placed near heat sources or inside sealed enclosures without airflow.
This is a through-hole, right-angle header — the solder tails insert into the PCB and are wave-soldered. For vibration-prone environments, a latching version would be preferred.
